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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
