2 years ago Irritatingly, I wasn't able to flash 1.0.0 or the original firmware until I made a cable with a RST connection, but now it works rather reliably :)
Sadly, the issue persists with the 1.1.1 firmware, and if I flash 1.0.0, I get a different, but similar output:

Hey,
this is not a bug report, but a question :)
I'm using an ESP32 to read/write the serial of a TSDZ2 with OSF as part of some experimentation for a project. I'm using 9600 baud, and was able to read the incoming packets from the original firmware, including 0x43 start byte etc.
After that worked, I flashed the recommended opt data and OSF 1.1.1 according to instructions (with stmflash8 on Mac), and now this is the output I get on serial/motor tx after connecting the motor to battery (I'm printing bytes read in hex with a space in between, the "[nnnn] reset frame size" strings are debug messages) without having written anything to serial/motor rx from the ESP32 side:
if I reboot the controller, it will again start the same pattern, that will change after a few seconds, so this is repeatable and consistent.
I know to support my experimentation is way beyond the scope of the devs here, but I thought it might not hurt to ask: did anyone experience something like this, or has an idea where I could look what's going wrong here? I've read the OSF source (specifically ebike_app.c), and I'm not finding anything that writes to serial that would do this.
While I haven't been able to use it yet, looking at the source this seems like an amazing project where a lot of effort went into it. I'm very impressed. Thanks for all your time, I hope I can be of some help in the future.
