Hello!
I have STM32H743 and 2 memory IC - MT25QL128
I create array with data 0x01,0x02,0x03,0x04.....0xFF and write it to flash
In singleFlash mode system works good.
But in dualflash I see :
00 88 02 88 04 01 06 03 08 05 0A 07
From Flash1 system reads 00, 02, 04, 06, 08 - it is correct.
From Flash 2 system must read 01, 03, 05, 07. But it reads 88,88, 01, 03, 05, 07
If I get out MT25QL, and mount W25Q128 (without code modification) - all work OK.
What is the possible reason of it?
How to fix?

Configuring non-default dummy cycles into one device and not the other.
