AM62P: snagrecover error

Part Number: AM62P
Other Parts Discussed in Thread: AM625,

I'm using AM62P5 Processor usinf TI's BSP linux 6.6 and I'm using this command 
We made a custom hardware based on AM62P-SK-EVM

$ snagrecover -s am625 -f ./am62px-lohr.yaml, and I had this output

    Thank you, 

    Now I'm having this output when power up the board

    On my previous board (AM62P STARTER KIT EVM), I had this output

    Whats the difference between SPL 2024 e SPL 2025?

    I assume that your issue was resolved after following the steps in the shared guide, please confirm the same.

    It is just some version difference, maybe you were using an older SDK version previously.

    Best Regards,

    Meet.

    Hi Sergio,

    Please allow me some time to test this on my EVM.

    Best Regards,

    It seems like u-boot is not able to find the filesystem, could you confirm what all images you have flashed to eMMC, you can share your Snagfactory yaml configuration file you used for flashing.

    Also, it would be helpful to know how you were able to resolve the earlier issue.

    How can I do that "share your Snagfactory yaml configuration file you used for flashing."? I've never used this tool.

    Then can you let me know how you are flashing these images to the eMMC and what all images have been flashed?

    I'm using Balena etcher with a .wic that I created with a storage.ext4 and a rootfs.ext4. My system was developed based on k3-am62p-sk.

    According to this output, the eMMC is partitioned into 4 logical partitions but there is nothing in the "/boot" directory of the second partition. Since, the bootpart is set to "0:2" in the environment variables, the U-Boot will try to load the Kernel and the DTB from this partition.

    If you have flashed the rootfs to another partition then please modify the bootpart environment variables to that partition.

    Thanks, that resolved my problem. Now when I enter in the kernel it appears strange charaters as shown bellow. Any thoughts about it?

    I do not see the kernel logs. The logs stops after the R5 SPL itself. Is that the issue? If yes, how did you confirm that the kernel is booting successfully.

    I'cant confirm, but it appears some messages, but all of then in this format "��� ����ͭ�ݮKc����ˬ,����-����� �ٹ��렫�;�r$h�2��j-Ƚ4hˮ��'٦��ͅ"�����."

    Hello,

    Just a few responses back, I could see that you were able to completely boot to A53 U-Boot. But, the latest logs don't show that. What is changed now that garbage characters are coming on the UART console?

    I've figured out, it was my bootargs.
