I had some issues with the cross compiler, mainly since U-Boot needs or more recent gcc, that's why I added a section/example with gcc v7. It took me some times to find the correct configuration, that's why I do this changes, for people like me :) But yes the 'python' part is the most important I think, to avoid failing compilation on some Linux OSes. As for the other changes, if you think that they are not needed no problem, I can remove them. > >> >> > $FIPDIR/blx_fix.sh \ >> fip/bl2_acs.bin \ >> > > > Neil > -- Loic Devulder - Senior QA Engineer Container & Storage Solutions Quality Assurance team (qa-css) SUSE LINUX GmbH, Maxfeldstr. 5, 90409 Nuernberg, Germany GF: F.
