can’t flash CM4s through usb

Question

Hey I m not able to flash my CM4s through usb as the device does not showing on my Mac I have to use USB A C as I don t have any device to ich USB A anymore without using an adapter Any ideas Did all the steps from the docs but no luck And as I only have one light model my other two can t be flashed with SD Cards as they just sit there without reading the SD card at all

appinteractive · Answer

Ahhh and worth mentioning that the only device reading the SD card and being flashed is not accessible via SSH at all Pretty frustrating till that pint Not my fist pro setup but definitely the hardest

As for flashing please use node other than node 1 Node 1 is problematic on some boards so try it only if you successfully flash in other nodes

_dhanos_ · Answer

Then A to C cables rarely work You need A to A We ve heard of people having success with using USB Hubs with Macs with A to C cables but this is not a rule

_dhanos_ · Answer

As for the CM4 that has the SD card when you power on the node the red LED next to the node should turn on Do you see a green LED on the other side Also keep in mind that if you flashed for example Ubuntu desktop ssh server will not be installed by default but it is installed by default in the server version

and I flashed the dietPi like in the help section on the turingpi com site

appinteractive · Answer

also edited the dietpi txt and the other file accordingly could not see any hdmi output after flashing so I guess it worked as the settings deactivate hdmi

I also have problems with but only node 1 all others work fine And if you flashed the module in another node and then put it back in node one everything works Is there more information about this problem or a place where I can keep up to date

The first time it didn t show up for me either however it was detected by the rpi imager and I was able to flash it
