Microblaze support was never upstreamed in gdb. We currently use a gdb from the Xilinx Github repository, but this gdb is based on 7.6, and has never been updated in the last 4 years. There are no other active branches at https://github.com/Xilinx/gdb/branches. Xilinx has a slightly newer gdb, based on 7.7, available at https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb. However, it's apparently only available in the form of stack of big patches (https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb/files). Currently, gdb on Microblaze fails to build in various conditions: * Against glibc, with "error: conflicting types for 'ps_lgetfpregs'" * Against musl, with "error: unknown type name 'elf_gregset_t'" While those issues can probably be fixed, the fact that there is no active upstream significantly reduces the incentive to fix those problems. Therefore, let's drop support for gdb on Microblaze entirely.

GDB, the GNU Project debugger, allows you to see what is
|
|
going on `inside' another program while it executes -- or
|
|
what another program was doing at the moment it crashed.
|
|
|
|
This option allows to build gdbserver and/or the gdb
|
|
debugger for the target.
|
|
|
|
For embedded development, the most common solution is to
|
|
build only 'gdbserver' for the target, and use a cross-gdb
|
|
on the host. See BR2_PACKAGE_HOST_GDB in the Toolchain menu
|
|
to enable one. Notice that external toolchains often provide
|
|
their own pre-built cross-gdb and gdbserver binaries.
