I've seen this a lot with openocd and arm cortex-m targets. There's always lots of finger pointing, but it's "incompatible" gdb version and gdbserver version. It's to do with the gdbserver sending an XML memory map that your version of gdb doesn't understand. (or at least, doesn't understand receiving it from the target) The "easiest" is finding the "right" version of gdb to use with the gdbserver you're using, which may be an up or a downgrade. There's some workarounds with manually specifying target type architecture and pointing to local memory map xml files and so on, but it's increasingly ugly.
Seeing as it looks like the gdb is built by openwrt, can you check if it has xml support built in?
