Re: Update a bootloader from application (bootloader the bootloader itself)
Update: I got it working, but only for one cycle.
Means: I program the bootloader with the ICD, bootloader the main app and update the bootloader over the main app. After a power cycle, the new bootloader version is active and still booting into the main appication (nice!).
Issue: From now on, no flash access works anymore. Neither from main app nor from the bootloader itself. It seems, the flash erase function fails already (finishing after milliseconds). Can something during flash of bootloader happen, what makes future flash access fail? Can anything be locked?
