Latest revision as of 13:16, 31 January 2022
The STM32MP157F-DK2 is a development board starring the STM32MP157F system on a chip and a ton of peripherals.
This board is a newer revision of the STM32MP157C-DK2 and as far as I can tell all STM32MP157C-DK2 hardware documentation applies to the STM32MP157F-DK2.
Almost all you need to know about this board and its chips is available without signing any kind of NDA or jumping through hoops. Very very convenient.

Software[edit | edit source]
ST's provides STM32CubeMP1 as this board's support package. It contains:
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
- OpenOCD for JTAG
Bugs[edit | edit source]
Bugs we've found when porting the board to Buildroot:
- 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
Pinouts[edit | edit source]
See the STM32MP157F-DK2/40 pin pinout page for a textual description of the Pi header.
