Hi everybody, i've developed an external loader for a STM32H7A3IIK6 MCU to write and read, using STMCubeProgrammer, an ISSI QSPI External Flash [IS25LP128F]. The External Loader works perfectly except for the following issue : the first time i open Cube Programmer and try to access the External Flash Memory [read or write] the Init function fails [even if i do not power cycle the electronic board]. Could it be a problem related to the "ld" file [here attached]?

Hello @Community member ,

I recommend you to take a look to the External QSPI loader MOOC.

And, try to follow the steps descripted in this MOOC in order to develop your external loader project.

I hope this help you!
