A big problem with Arduino 1.8.15 and Teensy 4.x

Hello,

I recently took out my Teensy's 4.1, which I haven't used for a long time, reinstalled the ArduinoIDE 1.8.15 with Teensyduino 1.54 on Ubuntu 20.04.

Even with a simple sketch (see attachments), something happens to the Teensy that I don't understand:
  • I erase the flash by pressing and holding the button until the red LED flashes and lights, wait until the erase process completes.
  • Compile the sketch
Code:

Teensy seems to "arrive" somewhere in nirvana as soon as I upload any sketch.

Can someone help me to solve this problem please?

Is it a known bug?

Thansk in advance,
Michael

I ran it here on Ubuntu 20.04. Seems to work fine.

A couple suggestions...

1: Make sure you installed the latest udev rules. They were recently updated because of problems on various Linux systems.

2: Run "tail -f /var/log/syslog" in a terminal while uploading. The kernel should give you messages as the USB disconnects and reappears.
 
Hello Paul,

I've installed the udev rules file, which is distributed with the Teensyduino, there are no other files in /etc/udev/rules.d, which could override 00-teensy.rules.

The dmesg output looks fine:

This problem is most likely caused by the following problem:
The original Ubuntu kernel 5.8.0-xx is buggy (it is a known bug since last year!) and overheats the CPU and the nvme device.
To solve this problem I use the mainline kernel 5.10.xx. I have enough experience with linux kernel to configure and run it on Ubuntu.
But of course it is possible that I have set something wrong in the kernel. I just don't know what right now!

Any idea?
 
Here are syslog message I see on Ubuntu 20.04.

Yours seems to be missing the "cdc_acm" line. Maybe your kernel doesn't have a compatible cdc_acm driver module?
 
Hallo Paul,

You are almost right!
I configured cdc_acm as a module, but it doesn't load automatically when I plug in Teensy. With STM32 boards (NUCLEO-144 STM32H743Z2) it works.
After loading this module manually it works (again).
I'll put it in /etc/modules ...

Many thanks for your help.
