help me to figure out what the issue is here i have nanopi neo core board, which has emmc, awg ethernet and h3 soc i had to hack a lot to get this up, including uboot (m1+) not meant for th= at board and fdt is also my own for a while i ran current on it with just usb eth and everything was fine when i started using awg eth, i experienced 10% of chance of network failu= re on init and rest of 90% showed stray corruption=2E dhclient told me pack= ets are wrong size=2E ssh sometimes gave errors on mac=2E in failure mode, = it gets so bad that switch port reports only errors from that port=2E like = 50k errors=2E and no traffic is going or coming=2E although tcpdump shows s= omething, it won't actually get to other side=2E on ping, it seems to reply= but send out broken frames note, i'm not really that good in any of this it all gets fixed if i do ifconfig down/up cycle=2E well, apart from stray= corruption but how it fully gets fixed is when i wipe emmc clean and just use externa= l sd card then corruptions are gone, it boots up with network all the time did i configure hw wrong with my uboot or fdt hacks? is it broken hw? i was told test other boards but it's kind if difficult a= lthough i have more as they don't have headers on if it's my hw and my hacks, how does it get fully fixed if i just leave em= mc alone? this is the only issue i've noticed, there are no data corruptions on emmc= , etc=2E no panics no lockups=2E i only remember one time i noticed system = had rebooted without reason but i wasn't there on uart to look it so what's actually wrong here i'm wondering? h3 has good support i see=2E = how those issues be fixed too? i get that emmc gets little usage compared t= o cards so maybe there's actual bug there? i know it's kind of sd/mmc but with wider bus=2E i'm happy to try any patc= hes someone might have=2E just don't expect me to fully get what they do
