- 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... - CK 09:22 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: KSZ8995MA Ethernet Switch Support

- 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?
Thanks,

- 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... - TC 01:21 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Connecting JTAG to Mityarm board
