Thanks! RX-51 build of U-Boot in qemu cannot read mmc. It report error about bad voltage. This was problem also before that commit. RX-51 Linux kernel does not have any problem with mmc, special prepaired Maemo 5 image (with some SW on eMMC) from Nokia working fine in qemu. I ignored above problem in qemu, because mmc worked fine on real n900. But after that commit mmc does not working on real n900 too. -- Pali Roh?r pali.rohar at gmail.com -------------- next part -------------- A non-text attachment was scrubbed...
