in gdb just before you connect (after elf file is loaded) play with these show arm abi set arm abi (don't remember the different abi names in my head)
different arm abi has different g package length (some ABI has floating point registers, some has not, hence wrong packet length). This happens when gdb guesses the ABI used based on the ELF file, which some times missmatches with what openocd expects for the given target.
