TEBF0808 Ethernet w/ SDSoC
« on: November 29, 2016, 04:25:20 PM »
Hi there

We are trying to get a minimal working setup running with SDSoC and are having trouble to get the Ethernet interface working. When starting it with "ifconfig eth0 up" we get the messages
Code: [Select]
[ 1047.213683] macb ff0e0000.ethernet eth0: unable to generate target frequency: 25000000 Hz
[ 1047.221938] macb ff0e0000.ethernet eth0: link up (100/Full)
I expect this is probably due to the Si5345 not starting/not being configured. The command to set it up is mentioned in your wiki (https://wiki.trenz-electronic.de/display/PD/TEBF0808): "si534x /dev/i2c-13 0x69". But the script/program is not included (or I cannot find it) in the SDSoC demo project. Do you have some example/code/script to start the Si5345 in a SDSoC setup?

Best regards,
Lukas

Hi,

we have a SDSoC Example available on (include Linux and Bare-Metal Matrix multiplication excample): https://shop.trenz-electronic.de/en/Download/?path=Trenz_Electronic/TE0808/Reference_Design/2016.2/te0808_sdsoc
Here are some instructions: https://wiki.trenz-electronic.de/display/PD/SDSoC+Projects

Hi John

Thank you for the quick reply.

We have been using that example all along, and have been able to resolve the issues now:
1) a typo in the lab network configuration not allowing the device to connect properly, and
2) we added a Gbit/s switch in front of the device (we still did not find a way to make it work with 100 Mbit/s).

For us the issue is resolved this way, and thanks again for the assistance.

Best regards,
Lukas
