TWR-LS1021A: No sound card available in SD_BOOT mode with Kernel Panic in idle mode

skrishnakar · ‎02-05-2015

Hello All,

I am booting SDK-v1.7 on TWR-LS1021A (x3) board in SD_BOOT mode. Unfortunately I am seeing that "vf610-sgtl5000" sound card is failing to register. This is default kernel and u-boot from sdk-v1.7 (rebuilt with SD_BOOT support).
