Issue with Programming two MT25QL512ABB devices in dual mode using the STM32H747I

eziya76 · ‎2025-08-13

Hello,

I hope this message finds you well. I am currently testing two MT25QL512ABB devices in dual mode using the STMH747I, with the same driver for the MT25QL512ABB. After performing write/read verification and rebooting, I encounter issues during subsequent read operations, as it consistently returns 0xFF. I would greatly appreciate your assistance in sharing any insights or findings regarding the root cause of this issue, if available. Thank you in advance for your support.

Edit: moved from Issue with Programming NOR Flash MT25QL512ABB1EW9 Using STM32H735IGT6 to a new thread.
