gdb "Load failed" with STM32F429I-DISCO

[chrisdew]

I'm having a similar problem to #10 but that solution doesn't work for me. (I'm already using arm-none-eabi-gdb and connected to the stlink process.)

I'm trying to make the program 'minimum' from gcc-arm-none-eabi-4_7-2013q3/share/gcc-arm-none-eabi/samples/src work.

I've altered the ../../nokeep.ld script to use the addresses and sizes I got from the STM32 datasheet. It now begins:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 0x200000 
  RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x1C000 
}

I've also altered the ../makefile.conf to use CORTEX_M=4 instead of 3.

Where can I find more information on why the load is failing?

Thanks,

Chris.

P.S. Using readelf I noticed that several symbols are being put into very low addresses i.e. not those blocks which I've defined as FLASH or RAM.

Have I made a broken elf that will never install onto my board?

Closing due to inactivity of issuer, please test against latest tools in master or v1.2.0 (at time of writing). Feel free to open a new issue if the problem still exists.

Likely fixed in #251.
