Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a 4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD output, and the other available at the MPU’s port PG3. The SoM can be plugged into a carrier board using its three 70‑pin connectors. Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a microSD card port and various I/O interfaces. The device tree is based on the DKx boards. TF‑A was successfully tested on the board with Buildroot 2021.02 and U-Boot 2021.04.
