TWR-LS1021A rev x3 with rev.2 silicon does not boot uboot from SD card

[bob_behrooz]

TWR-LS1021A rev x3 with rev.2 silicon does not boot attached uboot from SD card.

SW3=off on on off off off off on   SW2=off off on off off on on on

This is error message:

U-Boot SPL 2015.01+ls1+g6ba8eed (Aug 18 2015 - 09:19:58)

spl: mmc init failed: err - -19

### ERROR ### Please RESET the board ###

The attached u-boot is programmed into the SD card correctly, I read it from SD card and compared it with original.

I tried the same attached u-boot and SW3, 2  settings on LS1021A rev x3 with rev.1 silicon and it does boot from SD card!  

What does "spl: mmc init failed: err - -19" mean?

Any suggestions? 

Original Attachment has been moved to: u-boot-ls1021atwr-sdk18-sd.bin.zip

Never mind; TWR-LS1021A rev.2 silicon needs a different uboot than LS1021A rev.1.

Hi Babek,

what do you mean by different u-boot. Just compile options or some addition patch for U-Boot in SDK 1.8?

Hello Klemen PORENTA,

SDK 1.8 is only used for TWR-LS1021A Rev 1.0 boards, for Rev 2.0 boards, you need to download "Linux SDK for LS1021A v0.4" from QorIQ LS1021A Dual-Core Processor with LCD Co|Freescale  .

Have a great day,
Yiping

Thank you all, now I have SDK for LS1021A Rev2 v0.4. Next I need uboot for SD and uboot for QSPI. Can not find instruction on building these uboot in SDK RM. Where should I look?

Thanks,

Bob

Hello Babek Behrooz,

Please use the following procedure.

SD u-boot:

$bitbake u-boot -c cleansstate

Modify the variable UBOOT_CONFIG as sdcard in meta-fsl-arm/conf/machine/ls1021atwr.conf.

$bitbake u-boot

QSPI u-boot:

$bitbake u-boot -c cleansstate

Modify the variable UBOOT_CONFIG as qspi in meta-fsl-arm/conf/machine/ls1021atwr.conf.

$bitbake u-boot

Please note that the generated u-boot image has already included RCW.

Have a great day,
Yiping

LS1021 Rev2 is nor supported in SDK 1.8, but in SDK-for-LS1021A-Rev2-v0.4. Only Rev1 is supported by SDK 1.8.
