Bumping to TI's most recent Linux 4.19 version (i.e. linux-4.19.94-ti-r72) does not fix compilation errors but allows you to cleanly apply the necessary patches. Two errors have been fixed: 1 Since commite88225ed88("package/binutils: make 2.41 the default version"), the Linux kernel is failing to build with this output: arch/arm/mm/proc-v6.S:267: Error: junk at end of line, first unrecognized character is `#' make[3]: *** [scripts/Makefile.build:403: arch/arm/mm/proc-v6.o] Error 1 The patch [1] fixes the issue. 2 Since commitdc0f7215c6("package/gcc: switch to 13.x as default"), the Linux kernel is failing to build with this output: In file included from ./include/linux/kernel.h:10, from drivers/ata/libahci.c:35: drivers/ata/libahci.c: In function ‘ahci_led_store’: ./include/linux/compiler.h:348:45: error: call to ‘__compiletime_assert_1154’ declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long) 348 | _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__) The patch [2] allows to cleanly apply patch [3] that fixes the issue.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
