yeah, you could probably make a little cli app that just serializes postcard to a bin file (and maybe pads it out), so you could have a bash script that was roughly (sorry for mixing rust + shell code here)

```
let mut ctr = 0;
loop {
    probe-rs download --chip BLAH --format bin --base-address 0x08000000 your-app.bin
    gen-config --ip-addr '192.168.0.{ctr}' --out config.bin
    probe-rs download --chip BLAH --format bin --base-address 0x0800F000 config.bin
    ctr += 1;
    /* wait for user to press enter */
}
```
