Bug reading the ID from the External Flash MX25LM51245G in STM32H735G-DK Eval kit board

[urrudelu30]

Hi, I am taking the source code from trying to read the ID from the External Flash, but I am having some problems, note very sure if there is maybe with the clock config.

The initialization of the OCTOSPI device seems correct: int32_t result=0; uint8_t *ID; memset(&ID,0,sizeof(ID)); Flash.InterfaceMode = BSP_OSPI_NOR_OPI_MODE; Flash.TransferRate = BSP_OSPI_NOR_DTR_TRANSFER; /Initialaize OSPI/ if(BSP_OSPI_NOR_Init(0,&Flash) !=0) { return 0; } /Configure the OSPI in memory-mapped mode/ //result = BSP_OSPI_NOR_EnableMemoryMappedMode(0); result = BSP_OSPI_NOR_ReadID(0, &ID);

When I reached the line "result = BSP_OSPI_NOR_ReadID(0, &ID);" the returned ID is 0x85c2c2 and it must be 0x3a85c2, seems like there is a problem in one byte.

any help?

Thanks, Aitor
