@antimix I experienced issues with my new Mk4 as well. In particular, at a certain height (on one specific part on one print only) it moved veeeeeeeeeery slowly (barely noticeable)....

I can confirm that the XFA changes work as expected, all commands are still call-able. The off-command works on the nRF52DK and nRF52840DK (but without PR #19926 ) it obviously...

It is very odd that only the Arduino Nano 33 BLE would be affected. My suspicion was that it might be related to the bootloader, so I flashed the Arduino...

Okay this is interesting... I just came back from lunch and wanted to print the device ID and now the error appears; ``` chris@ThinkPias:~/flashdev-riot/RIOT/examples/default$ BOARD=arduino-nano-33-ble make term -j12 /home/chris/flashdev-riot/RIOT/dist/tools/pyterm/pyterm -p...

Yes, lsusb confirms that too: For periph_usb: ``` Bus 003 Device 006: ID 1209:7d00 Generic arduino-nano-33-ble ``` For tinyusb: ``` Bus 003 Device 009: ID 1209:7d00 Generic arduino-nano-33-ble ``` These...

The defaule example compiled with tinyusb indeed does not seem to go into bootloader mode. When bossac is called, it should make the program go into bootloader mode. This should...

I can confirm it works now. In the previous comment, I did not call the `stty` command before `bossac`, so the flash process would not have worked anyway. But I...

The issue seems to be present on SAM21G microcontrollers as well: #20305

To test this PR, I modified the tests/periph/uart test a little bit and added significantly longer delays so a slow human (me) can read off the multimeter in time. This...

I can't add that as a comment, but you can delete the ENABLE_ON and ENABLE_OFF macros from lines 44, 45, 52 and 53. They are now unused. This is the...
