This is odyssey stm32mp157c starter Repository.
- The ODYSSEY – STM32MP157C is a single board computer that based on STM32MP157C, a dual-core Arm-Cortex-A7 core processor operating at 650Mhz.
- The processor also integrates an Arm Cortex-M4 coprocessor, which makes it suitable for real-time task.
- The ODYSSEY – STM32MP157C is created in a form of SoM(system on module) plus a Carrier board. The SoM has consisted of the MPU, PMIC, RAM and the carrier board is in Raspberry Pi form factor.
- The carries board includes all the necessary peripherals including Gigabytes Ethernet, WiFi/BLE, DC Power，USB Hosts, USB-C, MIPI-DSI, DVP for camera, audio, etc.
- With this board, customers can fast evaluate the SoM and deploy the SoM on their own carrier board easily and quickly.
- Download firmware from: https://files.seeedstudio.com/linux/ODYSSEY%E2%80%93STM32MP157C/stm32mp1-debian-buster-console-armhf-latest-2gb.img.xz
- Flash your TF card with Etcher tool which you can Download here: https://www.balena.io/etcher/
- Connect STM32MP157c's serial pin to your Raspberry Pi or your PC/laptop(via USB-to-TTL device).
- Connect 12V/4A power supply to DC jack or Just connect a USB-C(Type-c) cable to your Raspberry Pi or PC/Laptop on USB port.
- Open a Terminal, using screen or putty.exe(for windows) or minicom to connect to serial port via baudrate 115200.
- Login to system, Username: debian Password: temppwd
- Add full pack of dtbs for debian system.
