w/dummy driver and str710 the gdb memory map is incorrect.
This will cause gdb load to fail now that flash erase_address fails
with non-aligned
memory.
The quick fix is to revert gdb to erase all sectors in a memory range.
The better
fix is to fix the GDB memory map.
openocd -f interface/dummy.cfg -f target/str710.cfg
(gdb) info mem
Using memory regions provided by the target.
