Hi,
I referred Ubuntu-i.MX8M.pdf. I used AWS to create Ubuntu BSP.
I can not do "Step-9 replace filesystem" as mentioned in above said PDF, as my SD card is not mountable on AWS.
Now I have folder "ubuntu-rootfs".
Would you please guide me to know how to flash it on my SD card?
How to include/add kernel and ubuntu images into the folder "ubuntu-rootfs".
Regards,
Prashant
Hi,
Followed given steps:
1. Created ubuntu-rootfs.tar.bz2 on AWS server.
2. Downloaded on my Laptop having Ubuntu 18.04 LTS.
3. Connected 16GB SD card over USB to Laptop.
4. Formatted it using # sudo mkfs.ext4 /dev/sda1
5. Went inside the mounted folder : # cd /media/pch/216cfe51-d19e-443c-aea1-5295d81edd21
# sudo tar -jxvf /home/pch/AWS/ubuntu-rootfs.tar.bz2
Also tried it next time with # tar -xvJf ubuntu-rootfs.tar.bz2 -C /dev/sda1
6. Unmounted SD card and inserted on iMX8M Dev board.
7. Adjusted switches SW1101 and SW1102 to boot from MicroSD/SDHC2.
8. USB microB debug port connected to Laptop. Used Putty serial – ttyUSB0 (or 1).
9. Did not get anything on serial.
10. RED PWR LED was ON. Nothing else.
Would you please help me to understand what is going wrong? Why board is not booting up?
Regards,
Prashant
Hello prashant,
You can burn the sd card with $sudo dd.

Hi,
I downloaded prebuilt images : L5.4.24-2.1.0_images_MX8MMEVK.zip
Used *.wic from them on SD card.
Adjusted switches SW1101 and SW1102 to boot from MicroSD/SDHC2.
Connected USB microB debug port to Laptop. Used Putty serial – ttyUSB0 (or 1).
Did not get anything on serial.
RED PWR LED was ON. Nothing else.
What would go wrong?
