Latest HOS supported: 21.1.0

hekate v6.4.0 brought massive changes, in case you missed them check v6.4.0 changelog

hekate v6.4.2 changes

• Fixed an issue that could cause a black screen or hanging in hekate logo (Nyx)
  There was an undocumented silicon errata that affected a fraction of users with T210 (Erista) devices.
• A new forced 8GB RAM config payload is now provided for RAM modded devices
  You can use hekate_ctcaer_x.x.x**__ram8GB**.bin via rcm injection, payload.bin, etc, in case you have a modded Switch with 8GB ram.
  It will automatically set the ram config to update.bin too if it doesn't match. No need to copy it there.
  Just make sure you use the 8GB variant as the first injected/loaded hekate payload.
  You can see more about this in How to update. (Users with normal 4GB devices should not use it.)
• Several other improvements and fixes

Nyx v1.8.2 changes

• The HW Info fuses pane was greatly improved
  Compacted and grouped relevant values together
  Used the actual names only instead of register names where possible
  Product code and FAB/LOT codes will now show exactly what's on the die markings
• A Wafer graph was added in HW Info to show where the die was located in the wafer
  Pairing this with speedo, it might show which areas are the best on average.
• Fixed an issue that could cause hanging in Nyx init while hekate logo was showing
• Fixed an issue with dumping Joy-Con BT Pairing from Nyx Options menu.
• BPMP clock is now more stable and some badly binned devices might withstand a higher clock (bpmpclock in nyx.ini)
  That's by fixing another undocumented silicon errata that affects both T210 and T210B01
• Added checks to the Date/Time roller for Day so it doesn't allow it to exceed per month max day
  The checks existed when saving, although somewhat broken (fixed now), but now they are also visual.
• Several other improvements and fixes

BDK changes

• CLOCK: Refactored all module clock enable/reset logic into using SET/CLR registers
• CLOCK: The above also fixes an undocumented silicon errata that affects a fraction of T210 and makes SDMMC hang
• CLOCK: Improved PLLC init/config to mitigate an undocumented silicon errata that exists in both T210 and T210B01
• CLOCK: Refactored PLL lock delays
• FUSES: A fuse_force_8gb_dramid function was added that when called once, makes fuse_read_dramid(false) return a 8GB DRAM ID.
• MTC: minerva_init now takes minerva storage as argument in order to avoid using Nyx storage
• MTC: A new minerva_deinit function was added that automatically sets freq to 204 MHz and invalidates the config
• BDK: Removed dependency to Nyx storage from everything in BDK.

NOTE:
For maximum performance of UMS in Windows, you need to run nyx_usb_max_rate__run_only_once_per_windows_pc.reg, only once per PC you have.
It only affects hekate's usb device. You can also view that file with text editor and see what it does. Linux/Mac OS users do not need that.

How to update:

• Drag n drop bootloader folder into sd card root and hit merge/replace.
  No need to delete that folder first, especially if you want your configs and payloads.
• You can choose to update your RCM injection device or PC or payload.bin with the new hekate_ctcaer_x.x.x.bin or not.
  In any case, bootloader/update.bin, will be checked and if newer it will get loaded.
  update.bin is hekate and it is already copied with the bootloader folder drag n drop update process.
• For users with 8GB modded RAM, you need to update your initial payload at least once.
  The update.bin will get updated with the 8GB config automatically as long as a 8GB variant is injected or used as payload.bin.

Latest HOS supported: 21.0.0

hekate v6.4.1 hotfix changes

• HOS 21.0.0 support
• Fixed NOGC patches for HOS 21.0.0 (v6.4.1 hotfix)
• TUI now has a Load Nyx option in case the SD card was inserted later or init temporarily failed.

• HOS 21.0.0 support
  As always based on https://github.com/m4xw/emuMMC

Nyx v1.8.1 changes

• HOS 21.0.0 support
• eMMC Partition Manager
  A new functionality was added so users with bigger than 32/64GB eMMC can resize HOS USER partition to fit the new eMMC easily
  As a side-effect, since that mirrors a SD partitioning, adding/flashing Linux and Android partitions is also supported.
  All performance related tricks for SD are also applied here and to the HOS USER partition.
  As always, resizing HOS USER partition re-formats it.
  The functionality is hidden and can be accessed by holding Partition SD Card for 5 seconds.
• Many fixes/improvements to Partition Manager
  • Partition manager's FAT fs creation was further improved to additionally optimize performance for FAT records access on new partitioning/formatting
  • A bug was fixed when partitioning SD Card with Android Dynamic scheme that would cause the emuMMC partition to be offset by -30MB in GPT table
    Use Fix Hybrid MBR/GPT to apply the fix on existing setups
  • Fixed an issue on resized emuMMC where it would not allow HOS to create PrFILE2 SAFE record (can't be applied retroactively)
  • Fix Hybrid MBR / GPT functionality is now extended
    Added removal of invalid/out-of-bounds and empty partitions from GPT
    Added a fix for wrong emuMMC offset because of older bugged Android Dynamic scheme
  • An issue was fixed when creating 58GB FULL emuMMC on Switch OLED where it would be possible to overwrite the last 1MB of it (no need to retroactively fix)
  • An issue was fixed on resized emuMMC where it was invalidating backup GPT (no need to retroactively fix)
  • Raw based resized emuMMC in partition manager now allows up to 24GB (was 12GB)
  • FULL emuMMC sizes are not allowed in the partition manager anymore on upgraded and bigger eMMCs to avoid confusion with create emuMMC (it's not allowed there already).
• Improved Package1/2 dumping
  It can now dump and decrypt both main and safe (recovery) pkg firmware and also the relevant BCTs.
  Additionally, the FS kip that supports both FAT32 and exFAT will now be renamed to FS_exfat.kip1, while the FAT32 only one will remain with FS.kip1
• Automatic Daylight Saving Time support for clock was added.
  Since timezones do not adjust clock on the same date/time, it's done on an averaged timely manner to avoid TZ clutter.
  An issue was also fixed with calculating time/day/month.
  The pop up to adjust time will show up again on first boot. Adjust it accordingly to fix the bug and to select auto dst.
• Joycon as PC HID Gamepad improved
  It now allows OS to control the report rate in order for OS driver to not cause a pipe fail or congestion (it also fixes OSes where it gets disconnected)
  It's also possible for Host now to manually request input reports
• SD Card Info now shows warning if vendor of SD is fake
• All battery and power management ICs in Battery Info are now checked for communication errors and if the version matches.
  In case one of them can't be reached an Error! message will show up.

  Fixed verification % and bar if restored backup is smaller than partition
  Bar is now orange for restoring when writing to eMMC/emuMMC.
  Fixed bar color on restoring after verification
  Allow verification to be skipped for all parts in partial mode (FAT32 or small card) automatically after the first skip
  Corrected several warnings where it would refer to eMMC instead of emuMMC
• HW Info will now say when SBK/DK is locked and can't be read, instead of showing FF.
• SDMMC errors now update automatically after running SD benchmark to avoid reentering SD Card Info to check them
• bpmpclock is now extended from 3 to 5 modes. 4 being the slowest boost and 5 being the stock clock.
• Fixed not showing HOS version for 22 burnt fuses (v1.8.1 hotfix)
• Various fixes and improvements

• SMMU: Ability to disable smmu was added
• USB: Removed unused endpoints from descriptors and adjusted driver to not expect them
• USB: HID: Idle rate support was added for HID gadgets so badly coded OS drivers do not cause a pipe fail
• USB: HID: Get report support was added in case host wants to pull a report manually
• RAMDISK: Size was extended 1280 MB via reordering memory mapping
• FatFS: mkfs was improved further in order to optimize filesystem performance even more

Latest HOS supported: 20.0.1

hekate v6.3.0 changes

• HOS 20.0.0 support
• Config: Added pkg3 key support that replaces fss0 with the same exact functionality
  fss0 will still work for compatibility reasons but it's now deprecated.
  At some point fss0 will become obsolete, so make sure you update your configs to use pkg3 instead.
  The templates were updated to use that.
• Config: Added pkg3kip1skip key support. Only for advanced users, read README.
• Config: atmosphere key is now renamed to kernelprocid to match what it does
  Only advanced users that do not use fss0/pkg3 are affected by this
• Config: fss0experimental key was renamed to pkg3ex
• Fixed parsing of system_settings.ini for usb3 enable. Thanks @new-waifu for reminding that.
• Fixed an issue that could have caused black screen on stock booting in some rare cases (kernelldr related)

Nyx v1.7.0 changes

• HOS 20.0.0 support
• SD/eMMC Benchmark now shows 95th and 5th percentile industry standard IOPS info. It also now uses in-spec A2 test sizes.
  Additionally, the window was made more compact so the info underneath it is still visible for sharing screenshots.
  It's preferable to compare between sd cards on the same updated benchmark, because of the changes.
  The 95% best accesses is generally your expected performance.
  The 5% worst accesses shows degraded nand parts or copies from SLC/MLC to TLC/QLC nands, big cache flushes, bad controller management, fw bugs, etc.
• SD info now checks if card's A2 support is proper or not. White: full support, Yellow: needs quirks, Red: broken.
• SD info will now immediately show SDMMC errors before calculating free space in FAT partition
• Fixed an issue where emuMMC could fail to be found for backing up or restoring
• Fixed an issue where emuMMC could fail to be backed up
• RAM real capacity detection is now more robust
• Made Nyx a bit more faster.
• Fixed an issue where reserved Android partition size could be calculated wrong on the HOS leftover slider
• Fixed an issue where a window could not be closed with B button on Joy-Con
• Nyx reload will now check if nyx.bin still exists and not reload, so user can fix that with UMS again
• Various fixes and improvements

BDK changes

• DIRLIST: It now uses alphabetical ordering instead of ASCII based
• SDMMC: Do not allow out of bound accesses since they need a power cycle to clear the error
• SDMMC: Add performance extension register parsing support
• UITLS: qsort compare functions added for int, char and char case insensitive.

NOTE:
For maximum performance of UMS in Windows, you need to run nyx_usb_max_rate__run_only_once_per_windows_pc.reg, only once per PC you have.
It only affects hekate's usb device. You can also view that file with text editor and see what it does. Linux/Mac OS users do not need that.

How to update:

• Drag n drop bootloader folder into sd card root and hit merge/replace.
  No need to delete that folder first, especially if you want your configs and payloads.
• You can choose to update your RCM injection device or PC with the new hekate_ctcaer_x.x.x.bin or not.
  In any case, bootloader/update.bin, will be checked and if newer it will get loaded.
  update.bin is hekate and it is already copied with the bootloader folder drag n drop update process.

hekate v6.1.0 changes

• Fixed an issue where emuMMC sector offset parsing was failing if SD card was bigger than 1TB.
• L4T and ARC changes:
  • Allow boot partition to be exFAT
    This will need an update of the bootstack of various L4T releases. Mostly important for Lakka and for users that do not want to format.
  • Significant changes were done to Arachne for RAM OC to increase performance and stability
  • Several timings were improved and corrected for both T210/LPDDR4 and T210B01/LPDDR4X
  • Stability was improved for higher frequencies for T210/LPDDR4
    It also significantly affects high density ram modules like in 8GB configurations
    Additionally, they can be improved extra with the ram_oc_opt ac mode also.
  • Fixed an issue where sometimes timing reduction was not allowed on 1600 MHz
  • A new ram_oc_opt= parameter was added to support advanced ram oc configuration for both T210 and T210B01.
    Mostly for users with T210/LPDDR4 because of low frequencies and others that like to optimize (T210B01/LPDDR4X).
    Read more in wiki.
  • ram_oc_vdd2 max voltage limit was raised to 1237mV for T210. T210B01 remains at Jedec max of 1175mV.
  • Fixed an issue for DDR200 on T210 when RAM frequency was oc one

Nyx v1.6.0 changes

• Support was added for Android 13+ dynamic partition scheme and also raised system partition size to 3GB for legacy (Android 10-11)
• Fixed an issue where emuMMC sector offset parsing was failing if SD card is bigger than 1TB
• Fixed an issue with some sd cards showing incomplete info (e.g. ADATA)
• Improved fuses info (corrected major/minor and added parsed iddq info)
• 3rd-gen RAM modules model name from Hynix and Micron are now shown properly
• Hw info will now show per chip ram info instead of single chip and 2 channels.
• Joycon auto calibration on init was relaxed to fix an issue with drifting with HAL effect based joystick mods.
  Additionally, that fix was also incorporated in the Switch to PC gamepad USB mode.
• Added built-in 6axis calibration dumping for all the rest Switch SKUs and stick type for Lite for use in L4T
• Added info for sd card max supported bus speed and consolidate all UHS classes into one field.
• Added info about some LCD panel clones and new official revisions
• Fan is now controlled in a finer way

BDK Changes

• DRAM: Hynix 3rd gen ram was renamed to the proper model name.
• DRAM: Added extra info about Micron 3rd gen ram.
• DRAM: Added per chip MRR info
• HWINIT: reordered sdmmc1 power disable
• INPUT: Samsung touch panel was renamed to just TSP. BH2109 is manufacture date.
• SE: Added se_aes_cmac_128, se_aes_crypt_hash and se_aes_iv_updated_clear functions
• ACTMON: changed to average sampling
• MINERVA: Change pll input divider for 2200-2266 mhz and some other fixes
• UTILS: sprintf will now reject NULL terminated characters for %c
• UTILS: allow strtol to parse unsigned integers if base is 16 and number is positive
