850C; only v0.5.0 beta3 starts - with 'running' values; later versions show 'Error brakes' #109

Hi all, i finally upgraded both TSDZ2 and 850C to the latest OS version, but no startup, after 20sec the 'error brakes' is shown. As far is i could find this points to a communiction error. So i checked a lot of older versions and v05.0 beta 3 is the one that starts. v0.50. beta 8 and later did not at least. When i swithc on the v0.5.0 beta 3 values are 'running'; values for battery, speed and power are changing constantly, even without activating anything :(

I used the DIY cable for programming the TSDZ2, must be OK as both flashing and veryfying shows no errors. Regarding the 850C i'm not that sure as i (assume) here we just do the flashing, no veryfying.... but flashing just starts for any version after press on the (remote) power button of the 850C. Is there a way to check the flashing otherwise? For programming the 850 C i used the DIY version to acc. https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/Flash-the-firmware-on-860C-850C-using-bootloader

Hope this sounds familiar to one of the users. For now i would like to have 'any' version to switch back to be able to use my velo (that is where i installed it).

I'm also struggling with a sudden brakes (3) error that came without any warning. I was using the SW-102 for some time without problem.

I replaced the motor controller and tried again with the factory firmware. It still doesn't work : the motor is not giving power and sometime vibrates. Walk assist mode works though.

Still investigating. Might be the hall sensor on the motor that I had to repair some times ago. Not sure we have the same problem but at least the same initial symptom.

Follow-Up : it turned out that the motor hall sensor connector was defective. One the pin wasn’t fully engaged, it slipped a bit out of the white plastic thing.

Think my DIY bootloader is NOK. Assume the (yellow) Bafang bootloader should do better...

Still no luck after using the orginal APT flash box (yellow one)... seems like i'm stuck in 'incomplete' SW, missing a piece to startup properly...

PieterDerckx commented 3 years ago

I still did not get any response so far. so i add a picture of my issue Maybe someone recognises... what am i doing wrong...? 20210219_081748

Can be:

PieterDerckx commented 3 years ago

Can be:

  • motor no firmware installed
  • brakes active while booting
  • TX and RX lines incorrect connected

So you mean i must connect to the TSDZ? Oh i thought is should already switch on without connecting..... Do i need to have brake(s) connected?

Thanks for you very fast reply!

PieterDerckx commented 3 years ago

It is working now! Finally.

Many thanks for you effort!
