Hello Devlist,
during my process of upgrading apache mynewt from 1.9.0 to 1.13.0 I now
face the problem, that the binaries I generate are not running on my system.
As a starting point I used the iptest application and the
stm32f7discovery bsp package. This worked with the old mynewt version. I
run my own bootloader implementation, after booting, it jumps to
0x08010000 and starts executing from there. For this to work in the old
implementation I had to set
> _imghdr_size = 0x0; /* size = 0 for direct flashing */
in the linker script.
I can't find any corresponding setting in the new version. The only
thing I found is:
> INCLUDE_IMAGE_HEADER
which I set to 0.
For testing purposes I also tried to flash the image directly and use it
without the bootloader, this also didn't work.
When I debug my application I get following output:
> xPSR: 00000000 pc: 00000000 msp: 0x96f3b83c
It seems that my program counter is not set correctly.
Any help is greatly appreciated, thanks!
Jan
