Hi,
I am trying to update bootloader code from the main app. Before erasing the bootloader flash sectors, I disable all interrupts and enable them again after erasing the bootloader flash sectors. However, the MPU resets when it tries to send command over I2C. The debugger first says "running" then "running - a reset occured" and "running" again, When I suspend the code, it says "break at address 0x4 with no debug information available, or outside of program code."
I2C and some other peripherals use DMA.
Another thing is that, when I erase the whole flash and load only the main app, it crashes as soon as it sends the first I2C command.
For some reason the main app needs the data in the first sector.
What causes this problem?
Below you can find the linker file content:
