linux - Error in UBoot "Saving Environment to MMC... Writing to MMC(0)... failed Failed (1)"

Question

I am booting with Uboot a Open Industrial Linux in a TQMLS1028A. When I do some changes in linux and I reboot, all the configurations and files are delete.

I use the command saveenv in Uboot and this error appears

Saving Environment to MMC... Writing to MMC(0)... failed
Failed (1)

This is the output of printenv

To create the sdcard.img of the Open Industrial Linux Distribution (https://github.com/tq-systems/OpenIL)

I do the following First execute

make tqmls1028a_mbls1028a_defconfig

This creates a .config file. I edit this file to build tcpdump and iperf3 with the image, I do this by

deleting this lines of code

# BR2_PACKAGE_IPERF3 is not set
# BR2_PACKAGE_TCPDUMP is not set

and adding this two

BR2_PACKAGE_IPERF3=y
BR2_PACKAGE_TCPDUMP=y

Then after that I run the command

make all

Then inside of the output/image folder I can find the sdcard.img. Then with this image I make the boot device with the program Rufus (https://rufus.ie/). Then the boot SDcard I put it inside of the board

Answer 1

At the end what I did is to change the Operating System of the board by a recommendation of the Technical Customer Support of TQ-Group

I use a Yocto Poky distribution that is specifically for this board

Here is the link where you can find the steps how to download it and how to buid the image
