Ah, OK. I see. We do use them in flash less aka iNVM only mode as 8086:157b. > In my case with your patch > below as well as York's patch > (https://patchwork.ozlabs.org/patch/400628/) I still see failures.

As mentioned before for me only the unprogrammed i210 gives me grief as it does not assert the CFG_DONE bit in the EEMNGCTL register upon PHY reset. However the e1000_swfw_sync_acquire() always works just fine. > Any ideas? Maybe the flash less aka iNVM only i210 behaves differently. Let me enquire Intel about this as well, I anyway need to ask our rep about the latest eepromARM programming tool as we have an upcoming production lot of a few thousand units arrive any minute now. > I don't have any i211's but I'll see if I can get hold of an > unprogrammed i210 to test with. Sure, would be interesting to see whether yours behave equally. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
