Error -110, -84 when loading root filesystem

Jump to solution

Hi,

I'm trying to boot Linux (build with 2017.4) from an SD card on a UltraZed with a custom carrier card.  SD has two partitions BOOT (FAT32) and rootfs (EXT3).  The SD card's rootfs partition is at mmcblk1p2 and it appears to mount ok in the boot process, but then it gives errors while reading the actual files (see following).

[    3.658135] EXT4-fs (mmcblk1p2): mounted filesystem with ordered data mode. Opts: (null)
[    3.666241] VFS: Mounted root (ext3 filesystem) on device 179:34.
[    3.675599] devtmpfs: mounted
[    3.678740] Freeing unused kernel memory: 512K (ffffffc000c30000 - ffffffc000cb0000)
[    3.697232] mmcblk1: error -110 sending stop command, original cmd response 0x900, card status 0x400900
[    3.768593] mmcblk1: error -110 sending stop command, original cmd response 0x900, card status 0x400900
[    3.778000] mmcblk1: error -84 transferring data, sector 2122432, nr 32, cmd response 0x900, card status 0x0

These errors repeat a lot and then end in a panic (full boot log on pastebin). 

 

I've tried a couple of things:

- Reducing rootfs size by dropping QT

- Using auto-generated bootargs

- Adding "sdhci@ff170000 {    broken-mmc-highspeed;};" according to this.

- Formatting the second partition as EXT4

 

Any help would be appreciated.

Based on this, I switched to a slower card and it worked (mostly). I was using a UHS Class 1 (U1) (~10MB/s) card that had worked on development carrier cards, but not our custom one apparently.
