I’d be curious how the performance of the CM4 without eMMC compares to the A06. (Also assuming that the hardware all eventually works with fixes, like fan and printer, etc. Does the HDMI out work as well?)
I don’t have figures, other than “wow, that’s SO much faster!”
HDMI is working. As soon as I find my printer I will test it… :-/
Printer works for me with the default system (although I had to set it as the “default” for
lp to send data directly). I think the driver still needs work - same one as for the A and R cores - the default text size is pretty huge for a small roll of paper, and also I think CUPS has deprecated the type of driver that it implements - but it is functional.
I’ve now had all 3 USB ports recognise “things” (initially I had issues but I’ve since reseated everything).
I’m curious about the way that
lshw differs between the R01 and CM4 cores. The device enumeration is very different, but I guess that could be a function of the RISC V kernel being a lot older.
I’ve also now had the game pad buttons work.
Need to write a “user guide” for folks trying the image as a daily driver…
Would to read some tips for sure!
(I plugged in an HMDI display and it worked as expected - I know someone was asking).
A reply to the heat sink confusion, the clear plastic piece that was probably already fallen off the heat sink is the only thing you need to “peel off”.
The heat sink is copper on one side and black on the other side, no need to do anything other than try to get it to stick to the back case of the devterm copper side facing the Cm4 (the side will hang down and cover the fan pushing air away - very bad). Use tacton tape or thermal tape to tape the heat sink flat to the case, don’t worry about the cm4, it will touch as you close the case. Put the thermal paste on the copper side of the heat sink and tacton tape the uncovered areas - all of them.
Close the case and the cm4 will press into the paste/heat sink.
I’m guessing the idea is that the fan pushes air under the copper heat sink, passed the cm4 and away through other holes. I saw a few people asking for the “fan shim” before this came out that guided air to the A06 and this is essentially a hybrid shim/heat sink. I noticed that otherwise the cm4 would touch the case and they had to do something about it.
i install my CM4 lite modul with 4GB, copy the 32gb image in a SD Card but onyl a black screen
Mine isn’t working either, but working perfectly with the original A04 core. I’m gonna try and reseat everything, but things look rather solid. How did everyone get their CM4s running?
