OpenEPaperLink firmware for CC26xx based tags.

• CC2630: TG‐GM29MT1C / ST‐GM29MTF (sleep current: ~2uA)

• TI CC2630 ARM Cortex-M3 core, 128KB flash, 8KB SRAM, 20KB Ultra Low-Leakage SRAM, 24MHZ clock*, 802.15.4 2.4Ghz radio
• 2.9” ePaper display (UC8151 or SSD1680)
• SPI EEPROM (1M, W25Q80)
• Dedicated wake-IC
• NXP NFC controller (I2C)
• 2x CR2450 Coin cell

ST-GM29MTF uses the same PCB as TG-GM29MT1C, but without the LED and NFC chip (not soldered).

To program or read-out this tag you have two options:

• Connect BL pin to GND and power on (or reset if already powered on) to enter bootloader mode, then use cc2538-bsl to flash firmware via UART.
• cJTAG or JTAG programmer (J-Link or TI's XDS110), you need to solder the debug pins from the SOC, which is pretty hard for most people.

• Install toolchain
• Build: make
• Flash: make flash PORT=COM3
