Problems with SDCARD booting LS1021ATWR

khandavalli — Tue, 03 Feb 2015 14:21:22 GMT

Hi, I’m working on LS1021A-Twr hardware using QorIQ SDK-V1.7, according to Ls1021aatwr document SDboot is supported, I’m facing few issues w.r.t SDBOOT.

Following is my set-up description:

a) Hardware: LS1021A-TWR

b) Kernel-3.12.19, u-boot:2014.07

c) Booting u-boot,kernel and Rootfs are from the SD-CARD.

d) Rootfs uses Systemd

Problem Description:

1) With same kernel,rootfs booting from SDCARD, Audio card is not getting detected in case of u-boot compiled and booted from SDCARD, and is working perfectly with u-boot compiled and booted from NOR:

Sound Log Snippet when u-boot from NOR, Kernel & Rootfs SDCARD:

2) Compared the rcw_1000.rcw and rcw_1000_sdboot.rcw important difference seemed to be in LVDD_SEL modified it accordingly but there wasn’t any change.

3) Understood that U-boot-spl-pbl.bin which is used for SDBOOT is a combination of rcw+u-boot, can you let me know the process to independently flashing the rcw_1000_sdboot.bin with u-boot compiled for SDcard.

4) Also observed recursive crashes w.r.t CPU idle, when I left the board booted from SDCARD idle for 15-20mins when CPU trying to enter idle mode it was crashing,Please find below the crash log:
