JC 08:53 AM Software Development: RE: Booting from Nand
I would try to look to see if your nfs filesystem is trying to mount the sd card and thus causing it to hang.
Your bad boot log doesn't show the same "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)" lin...

I removed the timestamps and did a diff between the two logs and they don't show much difference. Jonathan Cormier

Thanks for the logs. I don't have time to look at them today so I'll try to check them out on Monday. Jonathan Cormier

Hi Jonathan,
So the NFS mount on NAND boot magically started working. I don't think I changed anything. Either way, I am still having a problem: NAND boot mount NFS filesystem ONLY when SD card is still inserted in its slot, else it f...

Can you attach the full bootlog in a text file? That error is standard for kernel couldn't find root filesystem. Jonathan Cormier
BJ 02:23 PM Software Development: RE: Booting from Nand
Jonathan,
Yes, we were able to mount the NFS root filesystem while booting from the SD card using the new MLO and u-boot files. In fact, we were also able to boot from NAND while mounting the filesystem from the SD card; its just the...

Bindu,
I can't see anything wrong with your environment. Are you able to boot nfs while loading off the sd card with the new files?
Jonathan Cormier
BJ 04:18 PM Software Development: RE: Booting from Nand
Sorry about the formatting on that last post! Yeah turns out using the new files works! The files that come on the SD card are probably not meant for NAND boot.
However, NFS filesystem mount is not working with NAND boot. Is there a s...

JC 03:01 PM Software Development: RE: Booting from Nand
Your flashing steps look fine. Let me know if anything changes with the new files.
The new sd card image has the latest kernel and u-boot. There were several bug fixes for nand. If you look at the boot/versions.txt file it contains...

Jonathan,
Thank you for moving this over. Kernel version on the board is 3.2.0+. I used the MLO and uBoot file from the SD card provided with the MityARM 335x dev kit. The sizes of these files from the SD card and the link you provide...

Hi Bindu. Can you confirm that you are using a mlo and uboot that was built with the following config 'mityarm335x_4kpage'. Instructions are here: https://support.criticallink.com/redmine/projects/armc8-platforms/wiki/Das_U-Boot_Port#B... Jonathan Cormier

Greg,
Have you been able to get the wifi calibration tool running on the evaluation board?
Thanks

Hi Bindu,
A lot has changed since this post was made. I've created you a separate thread that references this one so we can try to work out what may be wrong.

1. The CL and TI website suggest Ubuntu 10.04 LTS, but the LINUX kernel version is 2.6.37. How is possible to build 3.2 kernel for SoM on this Ubuntu version?
The kernel that is running on your build machine doesn't have any relation ...

Thanks for the information. Just to be clear, I am not having trouble using wireless on the evaluation board. I am only having trouble running the wifi calibration tool.
My understanding is that the wifi calibration tool needs to be ...

Hello Jesse,
We attempted to run the calibration tools as well, and have seen the same result as you. We are looking into the problem, but would like to point out that the wireless should work on the board out of box. The way to confi...

JC 10:42 AM Software Development: RE: 3.1 vs 3.2 Kernel MityARM-335x Dev Kit HDMI not working consistently
This is normal. As far as I'm aware the 3.1 kernel was never updated to initiate the HDMI chip and relied on u-boot as well.

Jonathon,
You're correct, I was using the commands from the wrong section. Unfortunately, following the correct commands leads to a similar result:

Just to be clear, there is a lot of additional output when I try to run the calibrator command. I can post it all if it would be helpful. Jesse Johnston
