<drmpeg> With the 1/2 inch standoffs that come with the board, it's 2 inches to the top of the tallest heat sink on the PCI bridge chip.
<drmpeg> But you have to have some room for the wire harness plugged into the power connector.

<rneese> I have re flashed the the 3 diff fw files and none get the network working
<rneese> the wifi works ut no ethernet
<conchuod> what else did you change recently?
junaid_ has quit [Ping timeout: 268 seconds]
<rneese> nothing we did 2 things we updateed from the 202111 firmware to the 2022 fw and we added the fix for booting other imgs
<rneese> so it allowed for booting from mmc0:1 2 3
<rneese> as our imgs boot from 1
<rneese> but its failing to see the nic before it eben reaches linux
<rneese> Net: Could not get PHY for dwmac.10020000: addr 3

<rneese> mmc works fine and boots . but not eth0
<rneese> bbiab running to store
<conchuod> What's up with line 87 -> 101?
<rneese> thats because we are not using efi or grub
<rneese> and we use partition 1 not 2 or 3
<rneese> I have a feeling I might have to get a uEnt.txt from someone and reflash the full env

<conchuod> nathanchance: PGOed toolchain looks good so far... It's 20% faster for my regular defconfig + image "packaging" run. But there's a bunch of fixed overhead in that & it's not a big config either.

<conchuod> ye jedix you're correct. solrize they've got a proper datasheet (in english!) on their github
<solrize> conchuod, thx
<solrize> machine translation heh
<dlan> for sv39, memory above 512GB will be considered as highmem?
<nathanchance> conchuod: woo! Take relatively free wins when you can get them since they don’t come often haha
<conchuod> I PGOed it against allmodconfig, which I;ll give a go tomorrow as it's late.
<conchuod> But I'll take 20% faster, that's for sure...
