Issues with MT25QL512 about stm32-external-loader HOT 3 OPEN

Hi @albertomercurio, are you still facing the issue?. I had faced same issue with MT25QL512 drivers, but solved after changing dummy cycle parameter inside function uint8_t CSP_QSPI_EnableMemoryMappedMode(void). Currently it will be set to 10, try changing to 8 and see the result.

What I followed for solving this issue:

You can get device datasheet from: mt25ql512 datasheet

In the driver code, command-address-data is set 1-1-4 which is for extended SPI, and dummy cycle set for 10 which is for Quad spi mode (Page 37 in datasheet). As per datasheet, dummy cycle config for extended SPI should be 8.

Thanks! this was perfect for me!

Hello Guys,

I am having an issue with the MT25QL512 embedded in the STM32H750_DK. I tried the same code from ST MOOC but didn't work, I tried also all possible configurations but no news. Do you have an idea what could be the issue? BTW, my problem is that I can't communicate with the Memory.

Thanks,
Ayoub
