I use ST-LINK utility V4.2 to program a code to external flash, always fail.

Attachment is my code. it include embedded code(start at 0x08000000) & external flash code (start at 0x90000000).

Platform : STM32L496G-DISCO

External Flash : MX25R6435F

Use the Cube Programmer, the ST-LINK Utility v4.2.0 is very flaky with external memory, and not the active development path.

It works for the most part. I'm saying from observation that development effort has forked, the branch that has development resources behind it is the Cube Programmer, moving forward migrate to that.
