External flash memory - External loader failure - STM32H735IGTx MX25L12833FM21-10G

[dgold.1]

Hello,

I have custom board with MCU STM32H735IGTx connected via OctoSPI to QuadSPI external flash memory MX25L12833FM21-10G

In order to flash the external memory I am using external flash loader based on the template in https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib 

When I am running from the embedded SW application the test template (include erase, write and memory mapping) the test pass OK.

When I am running the external loader from the cube programmer the read from 0x90000000 fails

When I am running the external loader from cube IDE I get 'Erasing external memory sectors [0 23] failure

Attached external flash BSP driver mx25l128_quadspi.c , loader template Loader_Src.c and MX driver octospi.c

Help will be highly appreciated!

Best regards
