STM32MP1 using FMC from CM4 core
We are using the STM32MP15 ecosystem 2.1.0 and buildroot build flow for a custom board. The custom board uses the FMC peripheral to connect to three FPGAs using an SRAM/PSRAM interface. We have successfully implemented this interface on the CA7 sid...
Why MPU's ST support is so slowly...
Could you please explain me why ST support is so slowly... I'm starting with STM32MP1xx MPUs hoping, that ST support will be fast and specific. But currently answer for even simple (and stupid) questions need to be wait for unpredictable time...We ne...
