TWR-LS1021A: udevadm settle - timeout of 3 seconds reached

Question asked by Chan Park on Feb 24, 2015
Latest reply on Mar 2, 2015 by Yiping Wang

Hi,

 

I have a 512MB SD card and a 8GB SDHC MicroSD card.

 

When booting from 512MB SD card, it is working fine.  But I see a udev timeout when booting from 8GB one.   

 

1) Booting from 512MB SD card
