Changing octospi to quadspi configuration on STM32H723

[Aries16]

Hello,

I am using QuadSPI in STM32H723ZGT6 which has OCTOSPI and I am changing octospi to quadspi in pin configuration and writing code also I had written same code for STM32H750VBT6 which only supports QUADSPI and I am using W25Q128JVSIQ Flash for this in H750 the same code is working but in H723 it is not working can anyone explain me why you can check my main.c file for both of the controllers I am attaching it below.

Hello @Aries16 ;

The datasheet of the W25Q128JVSIQ is 128MBits = 16Mbytes. We see the bit 24 is set  meaning 2^24 =16 MBytes. In STM32CubeMx you need to set the device size field to 24.

Also, it is recommended to enable Sample shifting (SSHT) in STR mode and disabled in DTR mode.
Delay hold quarter cycle (DHQC) enabled in DTR mode and disabled in STR mode.

Why do you use different sCommand.Instruction =0x94; //0x9F//?

Thank you.
