Describe the problem
I'm experiencing sporadic macOS kernel panics during uploads to a Seeed Studio XIAO NRF52840 board.
I have noticed that it happens at the following stage in the upload:
Performing 1200-bps touch reset on serial port /dev/cu.usbmodem101
To reproduce
Steps to Reproduce:
- Connect an NRF52840 board to the macOS system (SEEED studio xiao NRF52840)
- Open the Arduino IDE and configure it for the NRF52840 board.
- Attempt to upload a sketch to the board.
- When it gets to
Performing 1200-bps touch reset on serial port, a kernel panic might occur. - If a kernel panic did not occur, repeat steps 3-4 until it does.
In my case there's a crash every 1 in 10 flashes.
Expected behavior
The sketch should upload to the NRF52840 board without causing a system-level kernel panic.
Actual Behavior:
The macOS system crashes and restarts with a kernel panic. The error is a Kernel data abort.
Arduino IDE version
Version: 2.3.6 Date: 2025-04-09T11:22:51.016Z CLI Version: 1.2.0
Operating system
macOS
Operating system version
Sequoia 15.4 (24E248)
Additional context
The logs produced by the kernel panic:
panic-full-2025-04-19-230931.0002.txt
I've tried changing ports, USB-C cables and even switched to using a USB-A to USB-C cable via a USB-C adapter (Apple official)
I've never had a crash with an ESP32 board, only the NRF52840 which makes me think there's a driver issue in relation to Nordic.
The same crash also occurs at the same 1200 baud reset step when I upload to the board using PlatformIO instead of Arduino IDE.
My Mac has an Apple Silicon CPU.
