As Guo explained, upstream gcc does not support abi-v1 (only abi-v2), but ck610 needs abi-v1 [0] [1] To simplify things, we make the whole C-SKY architecture require gcc-9 or later, and add a single exception in gcc to force the ck610 to use the C-SKY port. Note that this does not change the default gcc version to be used for C-SKY: the C-SKY port is still always the default one; the gcc-9 version is only proposed as an alternative (except for ck610, of course).

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
