So I don't know much about Linux or the Raspberry Pi (Especially the compute module), But I've managed to obtain one that is using a custom/proprietary board alongside it.
All the thing is currently capable of doing is displaying ads that aren't of my choosing, and want to replace that with something like Puppy Linux.
I'm using a Windows 8.1 PC with the rpiboot.exe tool, trying to get it to boot correctly so I can install Puppy Linux onto it with something like Rufus, but it seems to refuse responding after answering with 4 bytes of data.
Some other online sources say to set one of the jumper pins (F6, I think it was?) to EN, but I don't know where that pin is on the board so I can't put it into USB slave mode to install the OS.
I can add pictures later, if need be; But for now, here's some basic info on the board itself to see if somebody can help me reprogram this board.
- Uses a NL-SW-LTE-TSVG Modem
- Has 2 USB ports: A USB 2.0 Type C and a USB 2.0 Type A
- Has a CMV1.1 connected
- Is currently connected to a functional Hydis screen, and some other speaker
- Does not have any other ports (That aren't pins) other than the 2 USBs
- Draws power from a 39.5Ah battery
- Has one set of four pins labled: DU, RX, TX, +3.3V (Power?)
- Has one set of 3 pins in 2 rows (One of them is power, restarts when touched)
- Made by Radiosmith 2016, model number 031-100-15
