wildcat_paris Posted October 21, 2016 Share Posted October 21, 2016 please, is it useful if I would test MBR/PARTUUID for XU4 (as Zador is thinking of)? (instead of the former LABEL testing I did for SD/eMMC for next) in case I am on the proper path as of http://forum.armbian.com/index.php/topic/2454-fel-mass-storage-or-writing-images-directly-to-emmc/?p=18115 Link to comment Share on other sites More sharing options...
zador.blood.stained Posted October 21, 2016 Share Posted October 21, 2016 Regarding XU4 there are these things to test: Initrd support that was added recently Not a real test, but more a request for test or documentation - check if mainline u-boot can be used both for legacy and next kernels, also what problems forced using 2016.05 version (compilation issues?) In case legacy u-boot is still required, check loading environment from a text file like it's done, for example, here: https://github.com/igorpecovnik/lib/blob/master/config/bootscripts/boot-pine64-default.cmd#L15-L17 In case u-boot environment is properly loaded, booting by filesystem UUID can be activated for XU4. 1 Link to comment Share on other sites More sharing options...
wildcat_paris Posted October 25, 2016 Author Share Posted October 25, 2016 @zador.blood.stain 1/ ok, pulled 3 files changes. Your UUID architecture is like a charm. On the 3rd testing, the SDcard was booting & system running (Jessie). I guess eMMC will be working as well because it was working with root=LABEL=rootfs (to be confirmed yet) 2/ initrd was already implemented and working for XU4 next, so no changes here. 3/ I will be looking when possible about why u-boot 2016.09 was not compiling. Still uboot 2016.05 can be used for both SD/eMMC (huge move from 2012.07) 4/ I will check if 2016.05 can boot legacy kernel 4/ I will be looking to add some lines of documentation boot details: U-Boot 2016.05-armbian (Oct 25 2016 - 03:01:42 +0200) for ODROID-XU3 CPU: Exynos5422 @ 800 MHz Model: Odroid XU3 based on EXYNOS5422 Board: Odroid XU3 based on EXYNOS5422 Type: xu4 DRAM: 2 GiB MMC: EXYNOS DWMMC: 0, EXYNOS DWMMC: 1 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: No ethernet found.

wildcat_paris Posted October 25, 2016 Author Share Posted October 25, 2016 my TODO list: 1/ (from zador.b.s) can you please test default branch on XU4 and report here? Last time command line didn't pass from u-boot to the kernel for some reason. 2/ looking why u-boot 2016.09 was not compiling. 3/ checking if 2016.05 can boot legacy kernel 4/ adding some documentation 5/ L-R1 https://github.com/igorpecovnik/lib/issues/511#issuecomment-256111716 Link to comment Share on other sites More sharing options...
