- If you would like to use the latest sd card image. Instructions can be found here: https://support.criticallink.com/redmine/projects/armc8-platforms/wiki/Creating_an_SD_Card
- JC 12:58 PM Software Development: RE: Booting Linux
- Excellent glad the guide helped.
Just so you know we updated the u-boot branch with timings for the DDR to run at 400Mhz up from 303Mhz.

- Successful boot of kernel 3.2 console messages. U-boot has been modified with new mii pin locations, so the kernel does not see the phy on board after booting. I can now debug the new mii phy location on my carrier board design.
- DM 12:14 PM Software Development: RE: Booting Linux
- Building the Kernel with your new instruction, version: mityarm v3.2, is booting correctly. I am using gcc-linaro-arm-Linux compiler(arm-linux-gnueabi/non HW float unit) as described by the TISDK 6.0. I do have the environment-setup file...
- JC 11:15 AM Software Development: RE: Booting Linux
- There shouldn't be any problem building the kernel with the SDK 06 version. Though I have not personally tested building the 3.1 branch that you are using. I'd recommend building the mityarm-linux-v3.2 as it has a lot of updates over t...
- JC 11:08 AM Software Development: RE: Booting Linux
- There aren't any changes in your .config file from the one in our AM335XPSP_04.06.00.02 branch.
- JC 11:06 AM Software Development: RE: Booting Linux
- Have you modified the kernel? If so were you able to boot using the unmodified version?
- DM 10:58 AM Software Development: RE: Booting Linux
- I have attached the .config file.
- I am trying to build the Kernel. After loading the Linux uImage file, I get the message:
"Uncompressing Linux... done, booting the channel" and there are no more messages.
Any Ideas?
I am using TI SDK Version 06.00.00.00
I am using...

- JC 04:20 PM Software Development: RE: Booting from Nand
- Excellent this is a known issue. On boot the filesystem will try to calibrate the touch screen if its calibration file is missing. This is impossible to do if you don't actually have a touchscreen. Its looking for a @pointercal@ in th...

- Hello again,
Thank you for your help so far; I have been making progress, but still stuck on the NAND boot. After booting the kernel and mounting the NFS filesystem, here is where is gets stuck:

- JC 04:51 PM Software Development: RE: Booting from Nand
- Looking at the diff I posted the alignment prints out in both cases. This is a normal boot printout.
From your bad log I can see the line that starts with "pvrsrvkm". I'm fairly sure this gets printed by the /etc/init.d/rc.pvr scrip... - BJ 04:00 PM Software Development: RE: Booting from Nand
- Hey Jonathan,
I tried putting a few echo statement in some of the /etc/init.d scripts, but no luck. The boot is stuck at the following line, which I don't see when I am booting from NAND, mounting NFS but with the SD card in its slot:

- 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... - JC 08:48 AM Software Development: RE: Booting from Nand
- I removed the timestamps and did a diff between the two logs and they don't show much difference.
