Correction:
I ran the bitbake with additional debug *MACHINE=mityarm335x bitbake -v -D -D -D -D console-image*
I run @MACHINE=beaglebone bitbake -v -D -D -D -D console-image@ prior to adding the meta-mitydsp layer as a baseline. ... Michael Karasoff

Mike,
Thanks for your quick reply!
Unfortunately, when I run *MACHINE=mityarm335x bitbake console-image* I still get the errors during the Angstrom parse. I've replicated this on a fresh Ubuntu 12.04 install and on the 10.04 Virtu... Michael Karasoff

MW 06:52 AM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

I was suggesting to build the mityarm335x machine, or else you won't pick up the u-Boot and Kernel from our git repository that has the needed mods to support the module. What I was suggesting is to build a standard filesystem image, su... Michael Williamson

03:20 PM Software Development: RE: Booting StarterWare image from NAND

Tim,
Yes we do have a plain u-boot from you. So if I understand this correctly the MLO, uboot and boot options
are already in NAND. So by putting our image into NAND (say at where the linix kernal would be) and then
modifying th... Anonymous

booting from NAND is really just a change to your uboot environment settings. If you have a stock u-boot from Critical Link, you should see a number of different boot options.
booting from nand would be something like

02:48 PM Software Development: Booting StarterWare image from NAND

Hi,
We currently have our MityArm based system (MityArm CPU module, custom board)booting
into uboot and then loading out StarterWare based image from the sd card by setting the
bootcmd to:
mmc rescan; fatload mmc 0 80000000 emb... Anonymous

I was able to recover my BeagleBone and BeagleBoard build environments by removing restoring the *EXTRALAYERS ?= ""* entry in conf/bblayers.conf. Yay! I suppose there is something in the MityArm layer that is causing this trouble.

Hello,
I am also trying to build Angstrom according to the tutorial on the wiki: http://support.criticallink.com/redmine/projects/armc8-platforms/wiki/Installing_Open_Embedded
I've been successful in the past building and Angstrom ... Michael Karasoff

MityArm (335x) SOM supports two RGMII interfaces and both interfaces support only 3.3V logic levels Alexei Shkurko

What is the electrical specication of the RGMII interface from the MityDSP? Is it 3.3 or 2.5V LVCMOS? Joel Meltzer

03:21 PM Software Development: RE: DHCP is erratic in uboot

Just to let you know that if you set the phy register 9 (1000Base-T Control) to 0x0000 (turn off advertisement
for 1000 full/half duplex), then DHCP will work in uboot. I'm still looking into DHCP at gig settings.

Thanks Tim,
I've been beating my head against a wall for a bit so hopefully there will be something good
there.

There is quite a long discussion on the TI e2e site about this very subject. I suspect some of it will be pertinent to your situation.... specifically the parts about the recv phy timings.

02:26 PM Software Development: DHCP is erratic in uboot

We are having problem getting DHCP to work consistently on are board that uses the
the Mity AM3359 module (and our KSZ9021RL Phy). Port 0 failing is normal but when
port 1 finishes autoneg, I see the DHCP requests go out on the line an... Anonymous

MW 03:13 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

So the simplest solution would be to build a "stock" image (minimal console image or something). That will at least get you a basic toolchain, bootable kernel and filesystem, and the open source software. Then you can add your own pack... Michael Williamson
