nRF54L15 + MCUboot + mx25r64 with SQSPI : Failed to open flash area on mx25r64.

Hello

I  tried to test OTA function with smp_svr example.

I want to use the external flash mx25r64 on nrf54l15-dk(v0.9.3) to store update Firmware over BLE.  SDK version 3.2.0 was used.

The driver and dts for mcuboot was configured with "sysbuild\mcuboot.conf", "sysbuild\mcuboot.overlay".

partitions manager was used with "pm_static.yml".

Before mcuboot start, mspi and flash driver was loaded correctly. 

Then mcuboot to read seconed image slot on external flash failed. could you give some advice for this issue?

The source code is attached below.

Hi Max, 
I'm checking internally to see what could be wrong. Just want to point out that there is another similar ticket but doesn't seem they have the same problem as you, at least in their case MCUBoot can read the 2nd partition
nRF54L15 + MCUboot + External flash with SQSPI: VPR problems 

So my understanding is that you have this issue on the first boot, before you receive any image to the second image partition, correct? If you disable MCUBoot, does the application can access the external flash and read/write there?

Yes,it happens on the first boot.
when mcuboot is disabled, the app can read and write the external flash.
