Looking at that log i would say your linker script is incorrect. flash 
cannot be written to like normal ram.

To use gdb load you have to tell gdb about the flash sections, normally 
this will be done automatically.

can you show us the OpenOCD config you are using?
better yet provide the full debug log.
