It seems that I'm getting different results reading QSPI flash from the APP vs MCUBOOT, with the exact same configuration. Writes appear to work fine from either, but MCUBOOT isn't able to read the flash, whereas the APP can.
Initially I was trying to track down why uploaded DFU images weren't able to be validated by MCUBOOT, which looks like this:
I'm starting to think it's because MCUBOOT isn't properly reading the image from flash. I am able to upload images via SERIAL directly to MCUBOOT, or via BLE to MCUMGR in the APP. In either case, I am able to see the uploaded image through MCUMGR from the APP, but neither shows up in the image list when accessing from MCUBOOT, see example:
Initial image list from BLE (APP/MCUMgr):
Initial image list from SERIAL (MCUBOOT):
Upload image 105CFF via BLE and see it was uploaded to slot 1:
Image list with both images uploaded via SERIAL:
Upload image 777E0 via SERIAL ,and view the image list:
View the image list via BLE and see slot 1 was in fact replaced with 777E0:
The DTS is identical for both applications. Here is the PM config:
