Nor Flash memory mapping works unexpected on P-NUCLEO-WB55

Charles_Li

I'm using MX25V1635F on WB55

Below, read/write functions work fine

#define SECTOR_ERASE_CMD 0x20
#define QUAD_IN_FAST_PROG_CMD 0x38

But in memory mapping mode, only few bytes correctly or even nothing right,

CS, SCLK work as expected but D0 seems like out of control, is there any idea?

Hello @Charles_Li ,

There has been a case created to resolve this question and we will be reaching out to you directly.

The code for the working read/write would be helpful, along with the not working memory mapped template.
