[Bug] GMMK TKL randomly locks up or spams bbbbbb

Closed this issue · 3 comments

Describe the Bug

If you press a key combination with 3 or 4 keys hold down, the keyboard either locks up or spams bbbbb or 3b3b3b3b. The bug is not 100% consistently reproducible. The most reliable method I've found to reproduce is to simply mash a lot of butons on the keyboard rapidly.

System Information

  • Keyboard: gmmk (v1) tkl rev3 with CPU VS11K13A
  • Operating system: Reproduced on both archlinux and windows
  • AVR GCC version: 12.1.0
  • ARM GCC version: 12.1.0
  • QMK Firmware version: 0.7.101 (on working sn32 branch)
  • Any keyboard related software installed?
    • AutoHotKey
    • Karabiner
    • Other:

Additional Context

If you use sn32 branch instead of sn32_master branch, the bug goes away.

Bug traces back to timer. Should be fixed with 238e200

Can confirm that my gmmk rev2 full size which was previously also spamming is now working properly. Thank you very much!

I can confirm that I can no longer reproduce with sn32_master. Thanks!
