Linux/TDA2EVM5777: Preparing SD card failed

Hi Sagar,

do you use a laptop with a built-in card reader? Can you try with external card reader (your SD card should appear ad '/dev/sdX'), there was a similar thread:

e2e.ti.com/.../2824446

Hello Yordan,

I am using a laptop with a built-in card reader; I do not have an external card reader.

Regardless of that, the procedure detailed in the guide should work for the in-built card reader too.

One of my colleagues was able to follow the same instructions and prepare the SD card without any trouble.

Is there anything else I can try?

Thank you.

Hi Sagar,

the argument for '--device' should be the parent device, for example with a card reader you could have /dev/sdb as parent (this node should be used) and /dev/sdb0, /dev/sdb1, ... for the partitions on the device. I am not able to try on laptop how sd card are listed in /dev, but I suspect that '/dev/mmcblk0p1' that you use might be the first partition of the card and parent device should be '/dev/mmcblk0'. Can you check if that is the case?

Regards,
Yordan

Hello,

I tried executing the script in the way you instructed. The script executed only partially though, with the following console output:

I modified the script to mount partitions p1/p2, instead of the regular 1/2. This resulted in the following output:

I cannot figure out what the problem is. Thank you.

Hi Sagar,

it seems that you had some progress with your modification. I am concerned about first 'ls' error and mkfs.vfat complaining about mounted fs. Can you check also this part of the script:

for i in `ls -1 $device?`; do
 echo "unmounting device '$i'"
 umount $i 2>/dev/null
done

and modify it to:

for i in `ls -1 $device??`; do
 echo "unmounting device '$i'"
 umount $i 2>/dev/null
done

Regards,

Yordan
