I recently installed copies of the most recent Arduino IDE (1.8.16) and Teensyduino 1.55 on a Dell D600 running Puppy Linux (it works pretty well on old computers). The combination _seems_ to work OK, at least nothing crashes. But the IDE Tools drop-down menu indicates that my Teensy4.0 is set up for secure code (and it isn't). The compiler also fails because the teensy_secure utility program uses a library that's not installed on the computer. Since my Teensy isn't set up for secure code anyway it's likely it either will be bricked or the upload will just fail.
The Dell+IDE combination works just fine for programming older boards like the Uno.
My other laptop, a Lenovo Thinkpad W530 running Ubuntu 20.04 LTS, has Arduino version 1.8.12 and TD 1.55 and it compiles/uploads to my T4.0 just fine. There is no "Teensy 4 Security" item in the Tools dropdown menu, either.
I don't particularly want to buy a more modern laptop to write code for my T4, and I don't want to move the Thinkpad into my lab space, which has no internet connectivity. Does anyone have any thoughts on _why_ my old H/W+S/W might think the Teensy is set up for the secure code option?
Thanks in advance--
