NFC crashes when reading tag #417

Closed marciogranzotto closed 10 months ago

marciogranzotto commented 1 year ago

Describe the bug.

On dev(9ef4b15f683419afba98556e9ad2b9cd674abc5b), when reading an NFC device, in this cases a FreeStyle Libre CGM device, causes a crash.

The message after reboot is:

Flipper crashed but has been rebooted MPU fault, possibly stackoverflow

This doesn't happen on the release version.

Reproduction

  1. Flash commit 9ef4b15f683419afba98556e9ad2b9cd674abc5b
  2. Open NFC app from the app menu
  3. Select read
  4. Try to read an NFC tag/device
  5. Crashes

Target

f7-C

What type NFC is used on your device? Can you send a result of the read (with release version ofc)

marciogranzotto commented 1 year ago

Well... it looks like it's also crashing most of the time in the main branch.

I've tried to watch the logs while reading the tag:

I've seen other crash messages though, like:

Also, when it successfully reads the tag, it crashes when I press the "More" button, with NULL pointer dereference error.

But here's its screen when it successfully reads the tag: telegram-cloud-photo-size-1-4986033182264634623-y

can you try on latest dev branch?

also do you have asset packs enabled?

how are you launching the nfc app?

does it also happen just right after a reboot?

the nfc stack has been fully refactored. please check if it happens on the latest release @marciogranzotto

also ensure that settings > system > heap trace = none

Very stale, and there's been copious amounts of fixes for nfc and nfcv, I believe this is fixed. Report back if you still have issues
