Issue Reading OSPI data register in STM32MP257D Processor

[Aks]

Hello 

We are currently working on reading NOR Flash(MT25QL128) device ID through OSPI interface on our custom board with STM32MP257D processor. During our testing, we observed an issue where no data appears to be written into the OCTOSPI Data Register (OCTOSPI_DR), even though we can see signals on the data lines of the NOR Flash chip.

 

 

Thanks & Regards
