Multiple concurrent BMP devices?

[jnz86]

Should it be possible to address, say eight, probes at once? All in different states of flashing devices?

I want to make a gang-of-eight / octopus programmer. I was thinking a raspPi, linux, eight BMP v2.3s. Then with python, run eight instances of the flashing program. At each port, detect, flash, wait for a new module, repeat.

The things I am not clear on before I start research on this are:

• Should there be an issue addressing eight at once? I won't be able to use PID as they will all be the same. I assume I can read a serial number of a BMP?
• Is there anything in the driver that would prevent concurrent use? Like getting some single semaphore item from the OS?

I think those are two main issues for now. Thanks!

Each BMP is entirely independent of all others, and just shows up as different USB devices on the host. If you run the project's udev rules then you can refer to each one by its serial number as in /dev/ttyBmpGdb8BB20695 (for an example).

You can use the GDB remote protocol to connect into 8 different probes and control them separately just fine as there will be 8 /dev/ttyBmpGdb[serial] devices, all independent. One GDB can't talk to 8 simultaneously as that's not how GDB works - it can only connect to one remote at a time and must remain connected during the whole load process; but that's not a limitation if talking the serial protocol from a Python script.. just wrap that up in a class or function and call that function with each of the 8 file handles concurrently.
