As stated in the headline, after running some spin tests I wanted to update the firmware of the esc with the
```
voxl-esc-upload-firmware-all.sh
```
the script failed after uploading the firmware at 30% for each motor. Now the motors rapidly blinks.
I'm using a voxl2 together with the voxl2 mini esc. 
Voxl2 has the newest SDK 1.4.3 version

output of the voxl-esc-scan.py

Tried to manual install the firmware but it loses connection after ish 30% of upload

@astro_phil Make sure that voxl-px4 is not running while you're trying to talk to the ESC.

```
systemctl stop voxl-px4
```

@tom 

That's the first thing i disabled/stopped.
I also ensured px4 is not running in voxl-inspect-services.
Even the voxl-esc wizard does run into the same issues.

I also removed any uart device from the connectors. Before testing the previous steps.

@astro_phil What SDK version are you running? `voxl-version`

## Reply by Alex Kushleyev (ModalAI staff) · 2025-04-09 01:09:54 UTC (in reply to tom)

@astro_phil , your ESC is currently in a state where the ESC firmware is corrupted, so it remains in bootloader mode, waiting to be flashed with firmware. It is not bricked (or maybe it is, depending on the definition of "bricked" :) ), as it just needs to be flashed and you are running the correct procedure.

I am unsure why this is happening, but it seems that it is not related to the ESC itself - the errors you are getting are coming from the DSP UART bridge (the UART that ESC connects to is actually routed to the DSP and there is a bridge application that allows to talk to the ESC from CPU via the DSP).

We will get back to you with more things to try.

@astro_phil Before trying the ESC commands can you double check that voxl-px4 is not running and then enter `voxl-reset-slpi`, then wait 5 seconds, and then try the ESC commands?

## Reply by Eric Katzfey (ModalAI staff) · 2025-04-09 01:40:35 UTC (in reply to astro_phil)

@astro_phil Can you also capture the `dmesg` output when this happens?

## Reply by astro_phil · 2025-04-09 08:48:20 UTC (in reply to Eric Katzfey)

@Eric-Katzfey 

This time it got stuck in the flashing progress.
and i got a fatal error on slpi as seen in the dmesg log.

I tried flashing the ESC over my PC with a USB to UART adapter, which worked flawless.
Trying to launch px4 now yields the same error messages.

@astro_phil Yeah, the DSP just keeps resetting. Either there is a hardware issue or some piece of software has been corrupted. Can you do a complete reinstallation of the SDK? Perhaps back down to v1.4.1 and just see if that makes any difference?

## Reply by astro_phil · 2025-04-10 08:06:03 UTC (in reply to Eric Katzfey)

@Eric-Katzfey 

I reflashed the voxl with the voxl2_SDK_1.4.1 
unfortunately, without any changes. 
Spinning the motors with the esc-tools does work for a couple of seconds but stops with a connection reset error aswell.
PX4 does not start at all and i still get the SLPI error in the dmesg log.
