TE0715 ethernet link problem

(1/2) > >>

svedach:
We usually use TE0715 modules with industrial temperature range Zynq7030, but now due to some circumstances we need to use commercial temperature range modules. There was a problem with the ethernet link - it does not up, and all modules with a commercial temperature range have this problem. The same design works fine on all industrial temperature range modules. Are there any differences in circuitry or something else between these modules? What could be the reason?

JH:
Hi,

Temperature range is no matter, speed grade also (because ETH PHY is connected on PS--> as long as you mean with Ethernet the  ETH over on board PHY). Can you also test one time our reference design. please,

Download includes also binaries, so you can test directly. --> Copy linux binaries of your assembly variant on sd card and boot from sd.

Can you tell me also the exact article number of both module.Or send me the serial number (it's on the small white sticker with QR code), of both modules to support@trenz-electronic.de , so I can check it in detail.

Unfortunately I can't use your firmware.
For example, modules with serial numbers 619453, 619454 work correctly, ethernet works, but modules 619449-619451 do not establish a connection. The project is the same for all modules.

why?

that's all TE0715-04-30-1C from 2020 --> all are commercial.

Can you share boot log of working and non working module?

We do not have a test board from Trenz, the modules are used in conjunction with our own boards which do not have an sd card
