@Jiaheng Wang  Noticed your problem, let me first check quickly if downgrading from 2.09 to 2.04 can be done through  fwupdmgr under Linux. We are also close to releasing an update to ed...

Hi Sir,   do you mind to share the screen for reference? because I didn't see any download link for our schematic in the windows download page   Best Regards, Ken

@Willy Tarreau Sorry, I didn't see your reply until now. I've been busy on other work unfortunately (including trying to get OpenBMC running), but I've made some improvements. However since I'm no...

@Jiaheng Wang ADLINK sent me a black DB40 board (it's "DB40-HPC") a few months ago and provided me with a preliminary user guide in June which explains the pin layout. Someone should be able to pro...

@Tu Ken Thank you for your quick reply. But the manual from your link is for the green version of DB40 board, It seems that the black version is different? From this manual the pin layout is the sa...

Since I updated the bios to 2.09 and meet many flaws. So I decieded to temporarily downgrade my edk2 firmware to 2.04. Because I cannot peform the downgrade via Capsule, I tried the following metho...

@Jiaheng Wang I just tried to figure this out too, but with no success. The schematic shows the following, but it doesn't appear to be useful.

@Kothandaraman Kannadasan Appreciate the reply, it works. Best, Alee

I remember someone doing some experiments using IBM Power 9 CPUs. Basically, thermal paste was much better than common termal pads, and indium termal pads were slightly better than pastes. Personal...

@Philipp Krause if you look at this discussion, the thermal paste could possibly be improved.   https://www.ipi.wiki/community/forum/topic/79192/compatible-coolers

My case is 3U, so a 4U coller wouldn't fit. Also, I don't know of any place to buy an air cooler that would fit here, so I can't really change the cooloer. For now, the case is open top sitting on ...

@Philipp Krause That seem too hot to me, and just 5 degrees lower than the throttling temperature according to the Altra Max datasheet. I'm not sure if you'd want to change the CPU cooler, or incre...

@Philipp Krause  Yes, the stock cooler may be difficult to handle the heat with more than 64 cores. If you want to use air cooler, maybe 4U is recommended. On my system, I'm currently using a...

@Willy Tarreau I met your situation, too. But Unfortunately, I just can't downgrade firmware from 2.09 to 2.04 using Capsule. I'm tring to use the bios on the carrier by setting some Jumpers on the...

True, similar here, with "sensors". I also have one sensor per NVMe SSD, and also one for my NIC. Apparently, the "apm_xgene-isa-0000" is the CPU sensor. By high system load for a dozen minutes, f...

I finally "fixed" it by upgrading to firmware 2.09.100.00 but it brought its new bag of problems (system now takes 7 minutes of silence before the EFI prompt and a few such anomalies). But the freq...
