Must be the one after 1c57eed66caf259b2bb6ab42ba6df8f0ce363f2a.

Same prioblem with me. With different versions from 4.07-4.10. After a few successful flights, the FC no longer boots. It is also no longer found on the PC via USB. I flew a round with the Dodecahexa today. Then I wanted to set 4 waypoints and the next test nothing worked.

probably related to this PR https://github.com/ArduPilot/ardupilot/pull/16304

FWIW I am testing one of these boards and there is significant DMA contention - I can see that this would cause issues for things involving DMA

This is the post I used https://discuss.ardupilot.org/t/watchdog-reset-in-flight-and-ardupilot-does-not-complete-startup-and-hangs/64447

I am having same problem can reproduce as follows. arduplane 4.08 matek h443 wing quad plane y3 2 tilt rotors No logs -- will try log before arming.

Task calibrate current sensor connect ground station 3dr telemetry. reverse props. qstabilize. arm power half throttle say 20A measures with wht meter. edit current measured to 20A. when saved motors stop, no response from APM. Reboot normal LED then permeant red and greenled permanent buzzer, no USB detected. Reading code seems to mean flash memory corrupt. re-flash arduplane.apj 4.08 still the same. Flash MatekH743_bl.hex indfu mode with inave configurator (noerase), Flash arduplane.apj 4.08 still the same. Fix Flash arducopter or any firmware other than plane. Flash arduplane all working again.

Also if you follow the issues link and run zero.bin run MatekH743_bl.hex flash arduplane also fixes.

I have not seen any posts this cause crashes, is this the case. Seems intermittent when saving params.

Also I would like to try 4.1 and the CRSF protcol, where can I get latest status of 4.1 Dev

Thanks

Steve

andyp1per commented 3 years ago

@stevereed66 can you try the same procedure on 4.1? There have been some significant fixes on 4.1 which I suspect resolves this for you. You can find 4.1-dev here: https://firmware.ardupilot.org/Plane/latest/

stevereed66 commented 3 years ago

Yes, Is 4.1 at a stage to fly, would like to try CRSF and RCIN

Get back tomorrow midday gmt.

andyp1per commented 3 years ago

I have been flying it without issue (inc CRSF) - but I don't think your procedure require flying?

stevereed66 commented 3 years ago

Ok loaded 4.1 commit 164da261f10f0f6559330cf1d2dba875dd757eea Author: Peter Barker pbarker@barker.dropbear.id.au Date: Sun Feb 7 08:20:57 2021 +1100 did same test. saved measured current 20 times. All worked as expected.

While I have your attention, hope you dont mind Set up CRSF on serial 3 protocol 23 rcin baud 57 all working telemetry, RSSI and RC control but the FM opentx sensor has now appeared but only shows QSTB mode and does not change as mode changes.

You are doing a great job, stay safe

Same prioblem with me. With version 4.09 stable. After a few successful flights, the FC no longer boots. It is also no longer found on the PC via USB. Has to burn the firmware again. This is the third time this happens.

rojulec commented 3 years ago

Same problem for me. Version 4.09 stable in my C1 Chaser Wing. About three flights and the H743 now hangs on boot and no longer on USB port. Inital failure happened in flight just after take off. Motor disarmed and I safely glide landed while I still had control. After repowering FC, it would not successfully boot up. I have a log (bin file) saved in sd card apm log folder. It it worth trying to work out what happend there or just wait for 4.10 stable to be released? 00000021.zip
