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?
DhanOS
01/03/2023, 10:51 PMCM4S-es are pretty unobtainable right now, much more than CM4, so that's be interesting
DhanOS
01/03/2023, 10:51 PMOtherwise, 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

01/03/2023, 11:00 PMOne has arrived and another two are on their way

DhanOS
01/03/2023, 11:05 PMOh, that's interesting
DhanOS
01/03/2023, 11:06 PMThese modules were pretty unobtainable so far, so there's not much knowledge about them
DhanOS
01/03/2023, 11:06 PMThey 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

01/03/2023, 11:07 PMI think you might be the first to try them out in TPi1 🙂

01/03/2023, 11:07 PMHehe 🙂
DhanOS
01/03/2023, 11:08 PMLet us know about the results 🙂

SimD
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 😂

DhanOS
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 😅

DhanOS
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?

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?

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

03/22/2023, 10:54 AMSeems to work well 😀
SimD
03/22/2023, 10:55 AMWorked fine now I’ve finally got around to testing it 😀

03/22/2023, 1:12 PMnice!

DhanOS
03/22/2023, 2:39 PMDid you try to run them fully loaded yet?
s
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?

DhanOS
03/22/2023, 3:06 PMI used a simple tool called...
stresss
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

DhanOS
03/22/2023, 6:32 PMNice!
DhanOS
03/22/2023, 6:32 PMOn all nodes?
s
SimD
03/22/2023, 6:40 PMOnly checked temp in one but it was running on them all

DhanOS
03/22/2023, 6:46 PMAh, so it's table then. That's super nice.
DhanOS
03/22/2023, 6:47 PMMaybe one day I can get TPi1 for myself somehow too 🙂

04/05/2023, 3:08 PMIf you don’t mind one that isn’t perfectly mint… I can send you one

DhanOS
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
