I have a custom board with STM32H747IGT6 MCU, which communicates with a S25HL512TFAMHI010 flash memory chip over QSPI. I have made several iterations of this board, and the QSPI communication has always been fine.However, on the most recent iteration...

I have a NUCLEO-G0B1RE board generating 4 PWM signals at 10kHz using TIM1, which is working fine.For my application I also need to be able to read 4-5 PWM signals in - so for now I am trying to read these same signals generated on TIM1 to test the in...

I have a custom PCB using STM32H750VBT6 MCU and QSPI memory chip S25HL512TFAMHI010. I have written an external loader file as per the instructions in the STM32 MOOC [I tried to put a link here but the forum doesn't let me]. Testing the QSPI driver in...

OK I've managed to get it working, although the solution surprises me somewhat.It turns out that in order for the memory mapped mode to work correctly, the Write Enable (0x06) command needs to be sent first. This only needs to happen once for each ch...

Thanks for this. I have double checked that all 6 bytes of the ID are the same on both boards (and also cleared the sCommand structure each time it is initialised, which doesn't change anything in the memory mapped mode unfortunately.) It also seems ...

Thanks for this. My code is already using 32-bit addressing - and the Memory Mapped Mode works properly with the same code on what *should be* exactly the same hardware configuration (the changes to the board for this iteration did not concern the QS...

Aha sorry, I think you probably meant the Memory tab in the STM32CubeIDE - yes, this also returns 0x9999 (screenshot attached)

Good point - I should have mentioned that my firmware can communicate with the chip in non-memory mapped mode - part of the initialisation procedure is to read the ID register of the chip, and this succeeds - code below: // Read ID registers sComma...
