Great news Leonid! Thanks for the detailed error messages.

Bob,
That was the problem. It's booting now.
Thanks everybody,

Leonid,
One more suggestion: did you untar the sample filesystem as root? Or did you untar it as a normal user?
For example (you'll need to adjust the filesystem.tgz location and name): Bob Duke

Tim,
It does boot with a MLO and uboot built from the repository. Just need to put our
SPI changes back in.
Thanks,

Ok Tim,
I'll pull that in and give it a try.

The error message you see about "Error - Factory Configuration Invalid" is because the u-boot you downloaded is too old (sorry about that)
and it doesn't understand the new factory config block.
We are in the midst of updating "e... Tim Iskander

Tim,
The error is using the latest mlo and uboot from the Critical Link website.

All the 3352 based modules use DDR3, so will all require the new u-boot.

Tim,
Just to add some more info. We tried booting from three different 3352 modules and
they all have the same issue.

Tim,
As a test I downloaded the MLO and uboot from your web site and got the following when trying to boot the 3352 module:

You should pull the latest from the AM335XPSP_04.06.00.08 branch on our git repo.
Support for the DDR3 memory configurations came along with a "base update" to the
newer PSP uboot.

Hi,
We've been running the 3359 modules for some time and have shifted to the 3352. The error

Hi Mike,
OK, those numbers were for the CPU running at 500 MHz. The speed of the CPU may change based on what power management scheme (the CPU governor) that is selected in the kernel configuration.
Our default kernel selects "per... Michael Williamson

Lenoid,
It might be helpful to put the filesystem on an SD card and make sure it boots from there.

LV 10:42 AM Software Development: RE: NFS configuration

Hi All,
I agree, it looks like the original issue is fixed and now problem is happenning after mounting nfs. Probably, when *init* is running. I tried to play with *init=* commands in u-boot, but it didn't help.
The file system on ... Leonid Volpert

MW 09:26 AM Software Development: RE: NFS configuration

On your host, can you type "sudo exportfs" and list the results?

JC 08:41 AM Software Development: RE: NFS configuration

Leonid,
It looks like nfs may be mounting. I'd expect an error similar to below if it didn't. Is the filesystem on the nfs server the same as the one on the sd card? How was it created? Jonathan Cormier

MW 07:53 AM PCB Development: RE: EMC Emissions from MityArm 335X MOdule

Hi Mike,
Hold on on that last post. We were looking at the numbers and something does not look correct (there should not be a 2 GHz clock or a 1 GHz clock, and the CPU should be running at 700 MHz).
I may have posted this premat... Michael Williamson

Hi Mike,
We needed to enable a kernel flag here. Here is a dump of the PLL derived clock tree from our dev kit. Most of these frequencies don't leave the CPU. The frequencies should be the same for you with the exception of perhaps... Michael Williamson

Hi Bob,

2. NFS boot is hanging after the following message:

Hi Mike,
I had our lead software engineer try to dump the clock tree per the information you provided but he could not access it.
I would appreciate if you could set up a rig and help us through it.
Thanks,
Mike
