| == Software == | |
| ST's provides [https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-mcu-mpu-packages/stm32cubemp1.html STM32CubeMP1] as this board's support package. It contains:
| |
| | |
| * [https://github.com/STMicroelectronics/linux ST's Linux fork]
| |
| * [https://github.com/STMicroelectronics/u-boot ST's u-boot fork]
| |
| * [https://github.com/STMicroelectronics/arm-trusted-firmware ST's ARM Trusted Firmware fork]
| |
| * [https://github.com/STMicroelectronics/optee_os ST's OP-TEE fork]
| |
| * [https://github.com/STMicroelectronics/STM32CubeMP1 STM32CubeMP1]
| |
| Most of this is open source and the forks are being mainlined to the parent projects.
| |
| | |
| ST-Link can be used by the following software:
| |
| | |
| * GNU Screen or any terminal emulator for serial connections
| |
| * [https://openocd.org/ OpenOCD] for JTAG

| Bugs we've found when porting the board to Buildroot:
| | TODO |
| | |
| * You need to probe the snd_soc_cs42l51_i2c module manually to get audio running
| |
| *The Wi-Fi uses a Broadcom chipset which can be a little buggy sometimes
