It boots for me from eMMC on Pinebook and Pine64-LTS, thus I have no hardware to debug it further. Moreover, Linux also does calibration on A64 for eMMC, do you experience any issues with eMMC in Linux? > U-Boot SPL 2018.07-rc1-00164-g117d5917d2 (Jun 16 2018 - 15:12:28 +0530) > DRAM: 1024 MiB > Trying to boot from MMC2 > unable to select a mode > mmc_load_image_raw_sector: mmc block read error > SPL: failed to boot from all boot devices > ### ERROR ### Please RESET the board ### > > Jagan. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
