Hello,

 

Can somebody help with the following:

When booting Linux from the SD-Card labelled MCIMX53SABREAI, LINUX, 110-77382 REV A and supplied with iMX53 SABRE AI board the Linux boot process fails with following log:

….

mmc0: new SDHC card at address e624

mmcblk0: mmc0:e624 SD04G 3.69 GiB (ro)

mmcblk0:

mxc_rtc mxc_rtc.0: setting system clock to 1970-01-01 00:00:00 UTC (0)

p1

VFS: Cannot open root device "mmcblk0p1" or unknown-block(179,1)

Please append a correct "root=" boot option; here are the available partitions:

1f00           16384 mtdblock0 (driver?)

1f01            5120 mtdblock1 (driver?)

1f02          262144 mtdblock2 (driver?)

1f03          240640 mtdblock3 (driver?)

b300         3872256 mmcblk0 driver: mmcblk

  b301         3868160 mmcblk0p1

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)

[<800084a0>] (kernel_init+0x120/0x168) from [<800349e0>] (kernel_thread_exit+0x0/0x8)

 

How can I fix this?  A hint is given that a correct "root=" boot option has to be specified from the available partitions.  Where is this option appended?
