Playing with the STM32MP2

The author describes their dream MCU, which would combine a 1 GHz Cortex-M7 or M85 processor with various features such as NOR flash, SRAM, RGMII MAC, and AXI Chip2Chip SERDES block, and discusses their efforts to work around the limitations of the STM32H7 FMC. They have experimented with pairing the STM32H735 with an external FPGA over FMC, but found it difficult to route on low-cost boards due to the FMC's pin requirements.
