Turing Pi 1 and CM4s

01/03/2023, 10:43 PMDoes anyone know if this will work? I’ve acquired a few CM4s boards with 8gb mmc. I’m guessing it should just work it’s just power I wonder about a little.

01/03/2023, 10:50 PMDo you mean CM4S, like a model, or "s" at the end is just a plural?
CM4S-es are pretty unobtainable right now, much more than CM4, so that's be interesting
Otherwise, if you mean regular CM4, I'm unsure how would you like to use it with Turing Pi 1? In this case I might be missing something.

01/03/2023, 10:59 PMNope there’s a seller in the UK who’s selling some CM4S modules with 1gb ram and 8gb mmc and they’re definitely in cm3 format. I’m guessing they’ll just work as long as I have a recent OS version but was curious if anyone else has tried
One has arrived and another two are on their way

01/03/2023, 11:05 PMOh, that's interesting
These modules were pretty unobtainable so far, so there's not much knowledge about them
They should be a drop-in replacement, yes, but there are some downsides - they're slower than CM4s, but, of course, faster than CM3s, the network is 100Mb/s (same as in CM3), etc
I think you might be the first to try them out in TPi1 🙂

01/03/2023, 11:07 PMHehe 🙂
Let us know about the results 🙂

01/03/2023, 11:08 PMDefinitely will do. Am hoping a lite version turns up soon that I could try in my free play cm3 but not expecting miracles 😂

01/03/2023, 11:09 PMThey might show up sometimes later during the year. The shortages should be over by the end of this year

01/03/2023, 11:10 PMI have a 5 node pi4 8gb cluster and full DeskPi Super6c already and cm3 lites for the tp1 so I don’t need them… but 😅

01/03/2023, 11:11 PMYeah, I fully understand 😄

01/19/2023, 5:27 PM@_simd did that end up working?

01/19/2023, 6:41 PMI got distracted by the tp2 arriving. But I did flash all seven and put them in place so it’s a start 😀

02/10/2023, 3:21 AMHi @_simd ,
Where can I get the CM4S?
u
_simd
02/10/2023, 5:44 AMThere’s a seller on eBay which I used: https://www.ebay.co.uk/itm/314362405454?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=HlMOti5fQIG&sssrc=2349624&ssuid=laRZW4xCQwG&var=&widget_ver=artemis&media=COPY but he only has that one model, 1gb ram and 8gb mmc

02/10/2023, 6:07 AM@_simd did it end up booting with these?
u
_simd
02/10/2023, 6:20 AMWaiting for a new psu as my previous had been used elsewhere since but I can’t see why it shouldn’t
Seems to work well 😀
Worked fine now I’ve finally got around to testing it 😀

03/22/2023, 2:39 PMDid you try to run them fully loaded yet?
u
_simd
03/22/2023, 2:59 PMNot yet was just happy they worked tbh. My TP1 is caseless so airflow is pretty good. Any suggestions for stress testing them?

03/22/2023, 3:06 PMI used a simple tool called...
stressu
_simd
03/22/2023, 6:09 PMOk have left stress -c 4 running for 75 minutes now and no kernel messages and get around 77.9 C temp using vcgencmd measure_temp
u
_dhanos_
03/22/2023, 6:32 PMNice!
On all nodes?
u
_simd
03/22/2023, 6:40 PMOnly checked temp in one but it was running on them all

03/22/2023, 6:46 PMAh, so it's table then. That's super nice.
Maybe one day I can get TPi1 for myself somehow too 🙂

04/05/2023, 3:51 PMOh, that'd be cool. I might even try to fix it maybe.

04/07/2023, 8:38 AMit's possible it just needs a reflow oven, but I really don't know whats wrong
a heat sink on the Ethernet switch is essential
