SPI txCRC wrong value

Hello,I am using SPI with crc enabled on stm32f429ig.The problem is: if master's SCK's gpio speed is configured as medium, everything works fine. BUT if it is set to veryhigh, transmitted crc (read from TXCRCR register) always calculates a wrong valu...

Resolved! OCTO SPI output impedance on H7-series

I have swapped from a custom PCB-board with a 6-layer stack using a STM32H725IGKB, to another custom board with a 4-layer stack using STM32H723ZGT6 (simpler package).I am using an external OCTO SPI on both boards, but I have R/W errors with the 4-lay...

STM32H745 FMC PSRAM 16-bit always sends 64-bit

Hello,I am trying to get the FMC to work in 16-bit synchronous mode but I only get an output with 4 clocks (64-bit) instead.In other threads [1], [2] I found that I should either switch the address from 0x60000000 to 0xC0000000 or enable the MPU, but...
