Error creating MCUboot files in OTA partition

[romainreignier]

I have ran the sketch STM32H747_manageBootloader.ino in order to try MCUBoot bootloader.

But when I try to install it, I have the following error message:
Error creating MCUboot files in OTA partition

And the board has the red blink SOS signal.

Do you want to install/update the default Arduino bootloader? Y/[n]
Choosing "No", will install/update the MCUboot bootloader.

MCUboot has been selected. Do you want to proceed? Y/[n]

A different bootloader type is available: v6
Do you want to update the bootloader? Y/[n]
Error creating MCUboot files in OTA partition

Creating scratch file
Flashed 0%

I have tried directly with the default v21 bootloader and then updated it to v23 but in both case the result is the same.

Do I have to change the flash split setting in the IDE? I have the default 1MB M7 and 1MB M4 setting.

Hi @romainreignier,
flash split is not involved in this process. It looks like there is an issue with the QSPI flash. Do you mind to run this sketch to format your QSPI flash and then re-run STM32H747_manageBootloader.ino

Hi @pennam
Thank you for you fast reply.
Which partition scheme should I use? 1 or 2?

[pennam]

both should work, the default scheme is 1

[romainreignier]

Ok, thanks.
Maybe a log message should indicate to run this sketch in case of an error in the STM32H747_manageBootloader.ino sketch.

[pennam]

my plan was to integrate the scratch and update file creaton in the bootloader itself amd remove them from this sketch, but adding a log message is a good idea. Let me know if formatting the QSPI solves your issue.

[romainreignier]

Yes, I have managed to flash MCUBoot bootloader. Thanks!

Should I close the issue or keep it open to remind you to add the log message?

[pennam]

Let's keep it open and i will try to add the message tomorrow to not forget.
