Please try this branch for your initial experiments https://github.com/frantony/barebox/commits/20160815.mediatek At the moment there is no PBL support for mediatek mips chips. You can only run barebox from u-boot. > > Where can I find detailed description of needed steps? First try to run barebox for qemu-mips-malta (big endian version is simplier). The qemu run instruction can be found in Documentation/boards/mips/qemu-malta.rst There is an old but stil usefull barebox mips compilation demo at youtube: https://www.youtube.com/watch?v=WWnX__5wJfg For cross compiling I recommend to use Debian linux: just install gcc-mips-linux-gnu package. > Note: I tried a "dumb compilation" (after rule-of-thumb configuration), > but I got link error: > > mcon@cinderella:~/vocore/prove/barebox$ > PATH=/home/mcon/vocore/prove/mipsel-buildroot-linux-uclibc_sdk-buildroot/bin:$PATH > make ARCH=mips CROSS_COMPILE=mipsel-linux- > CHK include/generated/version.h > CHK include/generated/utsrelease.h > ... > CC common/version.o > LD common/built-in.o > LD barebox > mipsel-linux-ld: arch/mips/boot/built-in.o: in function `main_entry': > (.text_bare_init.text+0xe4): undefined reference to `glob_fdt' > mipsel-linux-ld: (.text_bare_init.text+0xe8): undefined reference to > `glob_fdt' > mipsel-linux-ld: (.text_bare_init.text+0xec): undefined reference to > `glob_fdt_size' > mipsel-linux-ld: (.text_bare_init.text+0xf4): undefined reference to > `glob_fdt_size' > Unable to open input file barebox > make: *** [Makefile:784: barebox] Error 2 > > ... so I'm surely missing some relevant step. > > Thanks in Advance > Mauro > > _______________________________________________ > barebox mailing list > barebox@xxxxxxxxxxxxxxxxxxx > http://lists.infradead.org/mailman/listinfo/barebox -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
