The script works fine in the msys32 shell (or WSL) but you might need to edit it to fit the location of the files. Michael On Tue, 4 July 2023, 6:11 pm Soko, <ovms@soko.cc> wrote:
Hi Mark,
I have the exact bin & elf I'm using (I've compiled it myself back in the day...). I've also found the script you are mentioning, but it seems to be a linux script, I'm on windows. Looking at the script though - educated guessing - it just looks at the address in the ELF file. Opening the ELF file with an hex-editor in windows reveals it ends at 0x0240D5DB.
Do I have to translate the address somehow? Or is the a2l script doing more than just looking.
I've also uploaded the bin & elf (http://soko.yourweb.de/ovms3.zip) if you wonna have a quick look.
The backtrace (0x4028128f 0x402823bf) is more or less the only constant numbers I get with each crash. So if they are too short can I add/activate some trace which leads to more info without connecting to a laptop (my old devenv doesn't seem to work anymore, and it was Windows anyhow...)
thx Soko

To understand what is going on, you’ll need to get the ELF file for the *exact* build of firmware you are using, and then use the support/a2l script to decode the backtrace addresses to something human readable. If you can’t do this, you could try by letting us know the firmware version you are running, where you got it from (API or Dexters), and provide the backtrace addresses. If you are using standard firmware builds, you can normally find the .elf file by simply change ovms3.bin to ovms3.elf in the download URL.
Alternatively, connect the module over USB to a laptop/workstation running the development build environment and GDB stub running to capture the panic.
The backtrace you show below (0x4028128f 0x402823bf) does not seem to be valid (too short), and probably won’t help much.
Regards, Mark.

Hi guys,
Running happily my OVMS on my VW e-Up since 2020 it drives my crazy since today :(
It restarts roughly every minute with this status afterwards: ------------ Last boot was 28 second(s) ago Time at boot: 2023-07-03 21:25:07 CEST This is reset #1 since last power cycle Detected boot reason: Crash (12/12) Reset reason: Exception/panic (4) Crash counters: 1 total, 0 early

And now the crazy part: It only happens when I'm connected to a specific WiFi/network?!?!
What I've tried so far:
1. Factory Reset (multiple times) 2. Set a static IP address 3. Reconnect all cables and make sure all are snug and tight 4. Brought OVMS closer to the AP (only one, no mesh) 5. Restarted AP 6. Restarted DNS & DHCP Server 7. It even happens when I have no vehicle selected after a factory reset
It gets more crazy: My WiFi is via Unifi/Ubiquity. So I can have multiple SSIDs with the same AP. So all hardware involved is the same...
When I connect to SSID "E3200", which is network 192.168.254.0/24, the exception happens every minute or so. When I connect to SSID "SurfHere" which is network 192.168.179.0/24, everything works fine!
Do you guys have any idea why this is happening? I've tried to look at logs via Shell and "log level verbose" but nothing shows up. Is there more I can activate to log this issue?
Maybe my hardware is faulty... Where do I get a new OVMS here in Europe/EU/Austria? Do I have to import in from the UK ( https://shop.openenergymonitor.com/ovms/)?
