| ELB-1382 | Known Issue | UHS-I SD Cards May Fail Due to NXP PMIC Errata ER021: VSELECT incorrect set point | Apalis iMX8 | SDIO/SD/MMC | | Low | No |
Description: Note: Apalis iMX8 V1.1A and later do have C silicon or later PMICs which do no longer exhibit this issue and have successfully been validated with various vendor's UHS-I cards to perform at reasonable 85MB/s.
Certain vendors higher-speed UHS-I SD cards may fail due to NXP PMIC Errata ER021: VSELECT incorrect set point. E.g. on SanDisk Ultra or Extreme cards the following may be observed:
[ 290.252408] mmc2: host does not support reading read-only switch, assuming write-enable
[ 290.420738] mmc2: Tuning failed, falling back to fixed sampling clock
[ 290.427228] mmc2: new ultra high speed SDR104 SDHC card at address aaaa
[ 290.434886] mmcblk2: mmc2:aaaa SC16G 14.8 GiB
[ 290.485876] mmc2: Tuning failed, falling back to fixed sampling clock
[ 290.492630] mmcblk2: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0xb00
[ 290.587997] mmcblk2: p1 p2
[ 291.053334] EXT4-fs (mmcblk2p2): mounted filesystem with ordered data mode. Opts: (null)
[ 291.095778] FAT-fs (mmcblk2p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Workaround: Disable UHS-I modes by adding the property no-1-8-v to the affected usdhcX node.
- or -
Try slower or other vendors SD cards. Eventually, this issue will get fixed in a later NXP PMIC die revision. |
