VOXL2 Sentinel no wifi after new SDK

@craigphoenix said in VOXL2 Sentinel no wifi after new SDK:

It is strange that voxl-esc-board-detect.py runs normally upon after boot. But if I run voxl-esc setup_sentinel_v1, I get the Bus 12 error. And after that, voxl-esc-board-detect.py gives the same error until I reboot.

@craigphoenix if the SDK is hanging at the bus 12 error it most likely means there is an issue with your esc or with the px4 instance. I believe this part of the install actually occurs after the sys image is flashed so you should still be capable of adb shelling or sshing into the drone and then probing the esc via the other commands such as voxl-esc XXX - if this is the case what happens when you do this instead of leveraging the sys image install?

@Zachary-Lowell-0 I am able to adb shell and do voxl-esc setup_sentinel_v1. This invariably causes the Bus 12 error.

Note that prior to attempting this upgrade, we were using SDK 1.0.0 without any issues. Should I try downgrading to that version?

@Zachary-Lowell-0 Downgrading to SDK 1.0.0 using install.sh has failed again at the voxl-esc setup_sentinel_v1 with the Bus 12 error. Yet now the wifi is working again (???). How could changing back to the old SDK suddenly cause wifi to start working?

My Sentinel is obviously in a very confused state.

@Zachary-Lowell-0 Any ideas on the updates I posted? Thanks.

@craigphoenix , it looks like your ESC is fine since you can scan it with voxl-esc tools.

I would suggest the following:

upgrade to SDK 1.3.3 again and skip doing the vehicle (MPA) set up, so that the install script gets a chance to finish without updating the ESC
finish the install and reboot voxl
run voxl-configure-mpa to configure your vehicle
also check if wifi is working

I believe what is happening is that the new ESC update scripts are assuming the latest DSP firmware has been installed, but it actually does not take effect until voxl2 reboots, so hopefully this approach fixes your issue.

If postponing the ESC setup (part of voxl-configure-mpa) does not fix your issue, please let us know!

@Alex-Kushleyev Thanks for your response.

I ran all of the steps in install.sh except voxl-configure-mpa for SDK 1.3.3. After that, I hard rebooted and ran voxl-configure-mpa. It did not solve the problem.

The wifi does not work.
All voxl-esc errors reported earlier persist.
Error in voxl-configure-cameras.

executing: voxl-configure-cameras 11
cat: /sys/module/voxl_platform_mod/parameters/config: No such file or directory
first try failed, executing a second time: voxl-configure-cameras 11
cat: /sys/module/voxl_platform_mod/parameters/conf

When I try to downgrade to SDK 1.0.0, the boot screen reports version 1.3.3, voxl-esc fails as before, but the wifi works (??). The downgrade does not restore its functionality to pre-upgrade state.

@craigphoenix , thank you for trying.

I think something is going wrong with the SDK 1.3.3 install.

@tom , what would you recommend doing in this case?

@Alex-Kushleyev We did recently release SDK 1.3.5, that might be worth a try

craigphoenix

@tom SDK 1.3.5 did not work; same errors as reported in my previous post.

Can I send something back to ModalAI to be re-flashed, or have something sent to me?

tom

@craigphoenix If Alex doesn't have anything else for you to try then you're more than welcome to submit an RMA and our team will investigate:

craigphoenix

@Alex-Kushleyev Do you have any other suggestions? Thanks.

Alex Kushleyev

@craigphoenix , I think the SDK install is failing somewhere in the middle (but goes unnoticed) and the ESC update and wifi issue is a result of that. We have not see this behavior before, so it is best to send the board back for inspection.

Thanks!
