Booting LS1046ardb From SD Card - CRC Error

[boematic2007]

I've been following the read me on how to build a new image for the LS1046ardb from scratch and boot from an SD card.  The build finished without errors.  The flex-installer worked.  However, when I insert the SD card and try booting I get the following (see below).  It's the line that reads, "*** Warning - bad CRC, using default environment" that is concerning to me.  Does this imply that there is something wrong with the SD images and it has reverted to the EEPROM?  Everything boots and I can log into Linux but is it the SD Linux or the EEPROM Linux that I'm booting?  Note: If I remove the SD card there is no console output so I think I have the switches right.

Here is a list of the commands that I used based on the readme:

repo init -u https://github.com/nxp-qoriq/yocto-sdk -b walnascar

repo sync --force-sync

. ./setup-env -m ls1046ardb

bitbake fsl-image-networking

bitbake qoriq-composite-firmware

bitbake generate-boottgz

Then for the flex-installer:

flex-installer -i pf -d /dev/mmcblk0

flex-installer -f firmware_ls1046ardb_uboot_sdboot.img -b boot_ls1046ardb_lts_6.12.tgz -r fsl-image-networking-ls1046ardb.rootfs.tar.gz -d /dev/mmcblk0

Hello, 

The switch configurations is correct, you can see this in your log file:

Board: LS1046ARDB, boot from SD

Please share the process you did follow to flash the image on the sd card. what images did you use, BSP version and the process to flash them. 

Regards.
