4-1 ESC issue with idintify the ID

Abdullah01

Hello,

I have an issue with running the ESC where it's not recognize all the ESC. It's recognize only 2 out of 4.

When I run voxl-esc and select scan shows the below:

I tried to disable voxl-px4 and run the test, but nothing changed using systemctl disable voxl-px4

The issue is when I tried to upload_params the process has stopped and the files got corrupted .

The issue is not with the wiring, the motors were running without issue before the upload_params .

Also, I can't upgrade all ESC, it identify only 2 of them, and the other to can't be upgraded

So, what do you recommend me?

Thank you.

@Abdullah01 ,

Sorry about that, please follow the recovery procedure outlined here : https://forum.modalai.com/topic/2897/voxl-mini-4in1-esc-and-voxl-2/8 (at the bottom)

This upgrade issue should be fixed in the upcoming release.

Also, I just documented the recovery procedure here : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/dev/voxl-esc-tools/recovery.md

Thank you for your fast support.

I tried the ./voxl-esc-scan.py with the new voxl-esc tool and shows me the following

So, I can't recover the ESC, is there another way?

thank you again for your support

@Abdullah01 , this is odd! We can diagnose further..

Can you please look at the blue status LEDs on the ESC board and see what their behavior looks like after you turn on the power. The correct sequence should be:

turn on power
all 4 blue leds on ESC blink fast (10hz) for 1 second. The ESCs are in bootloader mode
after 1 second, bootloader times out, the firmware should start (if valid firmware is present)
- if the fast blink continues indefinitely on any of the 4 ESCs, it means the firmware was corrupted on that particular ESC, needs to be re-installed (i can tell you how)
then firmware starts and verifies params
- if params are correct, there should be a motor beep sequence (configurable via esc params)
- after motor beep, the blue leds will blink twice and turn off
- if there are any ESCs that blink slowly about 5-6 times, and have a "sad" loud motor tone, it means esc params are corrupt

Can you describe what you see or if possible make a video of the ESC LEDs upon power up?

Thank you

Abdullah01

@Alex-Kushleyev

I just checked the blue lights,

It starts with the 4 leds blinking fast then turn off after one second.

Then, blinking fast for ESC (ID 1 & 3) - the one which not working

Finally, Blinking Slow for ESC (ID 0 & 2) - the one which working

For the motors beep, there are no beep from them.

Here is the video

sorry for the bad angle, I can't remove the ESC for its place, took me a while to install it

Thank you very much

@Abdullah01 ,

It looks like two of escs just dont have correct params. Please try the vommand ‘ voxl-esc-upload-params.py —baud-rate 57600 ‘ .. and add your params file to the command as you did before. This will force the script to only use 57600 baud rate. Please try a few times if that does not work on the first time.

@Alex-Kushleyev

Thaaaaaaaank you very much. It worked
