The Pi sees the CMM2 , but seems not to recognize it as DFU capable ?

I did mine under windows, see here, but it was with �dfu-utils, so it may still be helpful.

Your issue looked like what i saw when I tried to use the USB B connection for the update.

I haven't tried putting it into update mode using the jumper, did you try using the update firmware command, which is what i used?

Then I had a choice between the CMM2's USB B connection (in place of power) and its USB A connection (in place of the keyboard).

(I didn't check inside for a micro B connection, I think only the waveshare models have that)

The USB B connection worked for making a serial terminal connection, but I had to use the USB A-A connection for the firmware update with dfu-utils.

Thanks !
I ' ve up dated it once with Windows ,
but using the ' Cube ' app .
I thought about trying the keyboard
connector , but don ' t have that type
cable .... Maybe I can figure out
something today .

I think there's two separate protocols, both supported by the Cube app, but dfu-util doesn't support the serial protocol used for the USB B connector (at least with how I had it set up - as I said, I didn't try the jumper). stm32flash on Ubuntu might, but I wouldn't know how to use that or safely test it.

And the micro-B socket probably works with dfu-util.

And I saw your picture at https://www.thebackshed.com/forum/ViewTopic.php?TID=12513&PID=152103#152103
It doesn't look like you've got the USB micro-B option either.

Since CMM2 is new, comming month SW updates may be coming, so prepare for a decent solution. Very logical is:

For an A-A cable, take 2 out of the Kazillion cables and cut the non-A part off.

On both A pieces solder wire to wire. Typically the wires are color coded. Solder same color together.

For Aussies and Brits:
Typically the wires are colour coded. Solder same colour together.

Or - you order from Ali or Ebay...

I got mine from an electronics shop. I also wondered about soldering an additional socket, USB micro-B or C, to the board, but that would require some more consideration.

Technology Marches On !

Good idea , but still no cigar ( back to Windows this time around )

In the U.S., you could have it in 3 days:

I used it directly, but you could plug it into a male-to-female cable.

Ordered a couple of these

I think I may be missing something besides hardware though

Yeah, unless there's something wrong with your homemade cable I would think it should work like a bought one.

I was wondering if you had the CMM2 powered through the A-B connection, while you tried the raspberry pi USB A-A connection update. I think I needed to do that when I used Windows and USB A-A.

Not sure if you're using the jumper or the UPDATE FIRMWARE command. I've now tested both with dfu-util in the other thread (though still with Windows).

Looking back, it seems the RPi is only seeing the CMM2 as "ID 04d8:00dd Microchip Technology, Inc." which doesn't look right.

I don't know what UPDATE FIRMWARE does, but if the switches are right I'd expect an ID like 0483:df11

I suspect the RPi is just seeing the Microchip MCP2221. (Which may be right for UPDATE FIRMWARE, but it may not.)

Once the STM32 is in DFU mode it is likely to just work (and have the ID I posted).

So, the RPi is happy and seeing things OK - but the STM32 just isn't in the right state (which suggests switch(es) in wrong setting / wrong cable / plugged in wrong).

Right ... The RPi sees the CMM2

pi@raspberrypi:~ $ lsusb # with cmm2

Supposedly either moving the jumper or
UPDATE FIRMWARE should instill the DFU mode
Then

pi@raspberrypi:~ $ sudo dfu-util -l

should give

Maybe Tx and Rx need to be crossed as with
