Ticket Name: Linux/TDA2: No reading u-boot.img

Query Text:
Part Number: TDA2 Tool/software: Linux Hi Expert, I'm running Linux Vision SDK v03.02.00(4.4.84) on TDA2Ex. After completing mk-eMMC-boot.sh, the following error occurred during startup. Could you please give some suggestion here? If the sd card can start normally, but it will fail in saveenv, is it related? Thanks in advance.

Responses:
Hi, Are you sure the boot and root-fs partitions are correctly mounted on the emmc partition? To ensure this, please follow the below steps: 1. Boot from SD card by using the below SYSBOOT settings (this is setting it to forcefully boot from SD card, you may want to halt at u-boot and run env default -fa and saveenv) : SYSBOOT[0:15]: 00001100 10000001 2. Mount the emmc boot and rootfs partitions of emmc using the mount command to ensure the boot and rootfs partitions are flashed correctly into EMMC mount /dev/mmcblkxpy /media/boot # mmcblkx is the emmc media, py is the boot partition mount /dev/mmcblkxpb /media/rootfs # mmcblkx is emmc media, pa is the rootfs partition If you're not able to mount it, please reflash the emmc 3. Once this works, please set the SYSBOOT settings to below (this is setting it to forcefully boot from EMMC, you may want to halt at u-boot and run env default -fa and saveenv): SYSBOOT[0:15]: 00011100 10000001 You should see the board boot normally.

Hi, 1. Halt at u-boot and run env default -fa and saveenv. 2. Mount the emmc boot and rootfs partitions of emmc. 3. Boot from EMMC, halt at u-boot and run env default -fa and saveenv. but the board not boot normally. Could you please give some suggestion here? Thanks in advance.

Hi, There seems to be an issue with MLO and u-boot.img built. Can you please checkout the tag 'REL_VISION_SDK_03_02_00_00' on u-boot and rebuild it? (run make linux from Vision-SDK). Also ensure your USERCONFIG (SW5) switch-settings is as below. SW5 [1:10]: 00101 00000 Regards Shravan
