Hey Mike,
That is unfortunate, I had assumed TI managed their PSP kernel like a normal upstream project. Here's hoping that they get the AM335X with device tree support in mainline stable soon. I'm not sure if you've looked at the r...

Thanks, that did the job.
The bad news is that 3.2.0 does not have KS8995 support. It seems that this only starts in 3.3.0

I don't think your compiled correctly or uploaded the correct uImage to the machine.
The "Image Name: Linux-2.6.34-rc1-00098-ga450029-" suggests that your are still building off the master branch, and not the mitydsp-linux-v3.2 branch...

I have found a branch 'mitydsp-linux-v3.2', which I assume is the one you referred to, which I am downloading now. I will let you know how I get on with it.

Raja,
Sorry about the delay but I did want to update the fact that I was able to have the debugger connect to my MityARM-3359 SoM through the 335x Development Kit from CCS5 using the XDS100v2 emulator.

Hi Charlie,
I guess the first question is, "what do you want to do with the switch?". As I mentioned before, we have successfully implemented the KSZ8995 into at least one design here, and if you have all the ports mentioned above co...

Hi Alex,
Thanks for your reply.
I will try with these files.
What are the sys-boot options i have to set while connecting to JTAG?

Hello Raja,
Attached are both a gel file and a ccxml file that hopefully will get you going. The gel file has been used previously and should work for you with the MityARM-3359 SoM.
The ccxml file is setup for use with the XDS510 U...
