Linux/TDA2P-ACD: Linux hang while coping root file system into Emmc Partition

Hi,

Could you share the full Kernel log?
Want to check if eMMC enumerated successfully.

Also, which version of SDK are you using?

Regards,
Vishal

Hi Vishal,

We are using vsdk 3.4 for TDA2px custom board. We are using default root file system mentioned on document 3.4(VisionSDK_Linux_UserGuide.pdf).


Please find the kernel log below:

Hi,

==1==

Comments on the logs:

Looks like there were some failures in enumerating eMMC @ HS200 mode, and it switched back to some mode (not evident from log)

I also see another CMA related warning at boot time, is this also expected?

The initially shared Kernel crash is coming from some file system operation

Hi Vishal,

Thanks for the replay on log shared.

1) Looks like there were some failures in enumerating eMMC @ HS200 mode, and it switched back to some mode (not evident from log)

Ans: As I said, eMMC connected on mmc2 powered with 3.3v. I have read comment on e2e is "When 3.3V mode is used, eMMC do not support hs200 (192MHz) mode", hence I have commented the hs200 mode in uboot as well as kernel DTS file. Section mentioned in mmc2 node.

I have refereed below link:
e2e.ti.com/.../2658631

Is am I misunderstood some thing?

2) I also see another CMA related warning at boot time, is this also expected?

Ans: I don't have any clue about this. Please guide me if I did something wrong.

Note: In U-boot, default support provided for 1.8 v with high speed mode but in my custom board eMMC is connected on 3.3v. Initially eMMC was not detected on custom board. But after commenting the hs200 mode in uboot dts file it gets detected successfully.

Please refer the below link for better understanding.
e2e.ti.com/.../719516

Hi Swapnil,

The crash in your post is pointing to some other generic portion of Linux Kernel. It is not pointing to MMC driver.

[ 1350.942058] PC is at __rmqueue+0x2d0/0x488
[ 1350.946171] LR is at get_page_from_freelist+0x6dc/0x978

Hi Swapnil,

In the partition table, you don't mention the type.
As long as you flash the image type you need to the partition and the component mounting the partition knows how to mount it, ubifs should work.

I will check if anyone from our team has tried this fs type.

Regards,
Vishal

Also, if the original issue is resolved, mark this thread as resolved and open a new question for ubifs (If you have more questions on it)
