I think I'm running into a related problem again. I can not permanently flash the stabilizer with the pounder on it.
With probe-run I can flash it once, but after a powercycle of the stabilizer, it goes into panic.
DFU upload and ST-link virtual mass storage also result in a panic. I'm using the before mentioned PR on a stabilizer v1.1 with a pounder v1.0 (I used
cargo build --release --features pounder_v1_0 to build the firmware)
The newer PR https://github.com/quartiq/stabilizer/pull/725 was attempted over DFU upload and also failed.
With a different stabilizer v1.2 without the pounder all three methods successfully flash the stabilizer at v0.7.0. With the stabilizer as above but without the pounder at least DFU upload works, the other 2 I did not test.
