The device is a pine64+ with 1 GB of RAM.
I am also using the PINE64+ with 1GB memory and I also saw some problems which I assume are related to MMC on my board. > Sometimes it fails before mounting the root: > > [ 1.273249] Waiting for root device /dev/mmcblk0p2... > [ 1.281238] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 55, RE RCE !! > [ 1.317715] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 3, RCE !! > [ 1.323864] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 3, RCE !! > [ 1.344409] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 55, RCE !! > [ 1.350097] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 6, RE RCE !! > [ 1.355941] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 55, RCE !! > [ 1.361651] mmc0: new high speed SDHC card at address cda0 > [ 1.367559] mmcblk0: mmc0:cda0 00000 7.51 GiB > [ 1.372415] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 18, RD RE RCE !! > [ 1.378609] sunxi-mmc 1c0f000.mmc: data error, sending stop command > [ 2.374894] sunxi-mmc 1c0f000.mmc: send stop command failed > > Sometimes it fails just after: > > [ 1.273185] Waiting for root device /dev/mmcblk0p2... > [ 1.342876] mmc0: new high speed SDHC card at address 0007 > [ 1.348790] mmcblk0: mmc0:0007 SD8GB 7.42 GiB > [ 1.354623] mmcblk0: p1 p2 > [ 1.401534] VFS: Mounted root (squashfs filesystem) readonly on device > 179:2. > [ 1.408891] Freeing unused kernel memory: 320K > [ 1.418724] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 18, RD DCE !! > [ 1.424659] sunxi-mmc 1c0f000.mmc: data error, sending stop command > [ 1.430953] sunxi-mmc 1c0f000.mmc: send stop command failed > [ 1.436564] mmcblk0: timed out sending r/w cmd command, card status > 0x400900 > [ 1.443601] mmcblk0: command error, retrying timeout > [ 1.449386] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 18, RD DCE !! > [ 1.455309] sunxi-mmc 1c0f000.mmc: data error, sending stop command > [ 1.461581] sunxi-mmc 1c0f000.mmc: send stop command failed > [ 1.467185] mmcblk0: timed out sending r/w cmd command, card status > 0x400900 > [ 1.474221] mmcblk0: command error, retrying timeout > [ 1.484737] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 18, RD DCE !! > [ 1.490670] sunxi-mmc 1c0f000.mmc: data error, sending stop command > [ 1.496956] sunxi-mmc 1c0f000.mmc: send stop command failed > [ 1.502550] mmcblk0: timed out sending r/w cmd command, card status > 0x400900 > [ 1.509598] mmcblk0: command error, retrying timeout > [ 1.516026] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 18, RD DCE !! > [ 1.521959] sunxi-mmc 1c0f000.mmc: data error, sending stop command > [ 2.524849] sunxi-mmc 1c0f000.mmc: send stop command failed > > Do you have any idea of what could be wrong? > > I also tried an Armbian image (based on Debian jessie, with a non-mainline > 3.10 kernel) and it worked fine out-of-the-box. > > Attached are full bootlogs for both LEDE and Armbian. Could you try an image build the sunxi branch of my staging tree please: https://git.lede-project.org/?p=lede/hauke/staging.git;a=shortlog;h=refs/heads/sunxi I backproted the MMC driver in there as it got some patches which are probably needed for the A64 SoC. For me it also boots up without these changes, but sometimes I also see some error messages. I never looked at the 3.10 kernel or booted it up, I only looked at what is in mainline. If we add kernel 4.14 support before the next LEDE release I will probably bring the sunxi target to kernel 4.14 as this kernel version has official support for the A64 SoC. Hauke
