So far, I hadn't managed to run those tools properly on OpenBSD. I was too confused by its stty peculiarities. I'm still confused, but at least I managed to make them work... most of the time... |

Tools
This folder contains tools to communicate to Collapse OS machines from a modern environment or to manipulate a blkfs.
Communication tools all take a device path as a first argument. That device is
the serial device that connects you to your machine. It's often a USB-to-TTL
dongle. When - is specified, stdin is used as the device.
Note that for these tools to work well, you need the serial device to be
properly set up, TTY-wise. You'll probably want to do that with stty. The tool
itself takes care of setting the regular stuff (cs8, -parenb, etc), but you
need to set the speed. Here's an example working on OpenBSD:
$ ( stty 115200 ; ./upload - a000 os.bin ) <>/dev/cuaU0
To be honest, I'm having a bit of troubles making these tools work as well on OpenBSD as they do in Linux. But it does work. Here are some advices:
- Use
cuaXXinstead ofttyXX. - Run
cu -l /dev/cuaXXbefore running your tool and run a dummy command to make sure that the output buffer is flushed.
On Linux, it's generally easier:
- Run screen on the device (often
/dev/ttyUSBX) - Quit with
CTRL+A :quit - Run the tool on the same device
