It seems that if programming the Teensy using the ADS1x15 library in combination with GDBStub just kills the entire USB communication. So here's the tricky part it fails *directly* after uploading and it does it very repeatedly.

: after the 15 second Restore, UNlike when factory new that Blink code does present as a USB device of type RawHID and ready for programming without a Button push. until then it will sit offline waiting and not 'Reset'.Īlso, interesting - another case of using PIO and having a Teensy end up in the 9 Blink state? But it ran for some time after upload? Or did it take time to get it to builod and fail right after uploading? While using debugging? It will always take the Teensy offline to bootloader mode - if the Teensy Loader is active - or when it becomes active - with a sketch to upload it will upload and restart.

Also, historically PJRC chose to not put USN even in the factory blink as (IIRC) it caused grief on older Windows when a driver had to be installed before plugging it in would go without issue.Īnd the Button is 'Program' not 'Reset'. that simple Blink fits (IIRC) in a 4KB block to minimize flash loss - with USB would be much larger. My other Teensy (i am a klutz so i got two) however gladly enumerates as a USB device still.ĭid i manage to kill it somehow? Is Visual Studio Code the bringer of doom?Īs noted in p#2 - it is doing well if running 'Blink' after the 15 second Restore, but like when factory new that Blink code does NOT present as a USB device. Okay so now i noticed its blinking 9 times whenever i plug it in which apparently signals some JTAG issue? Anyway i reset the thing by holding the reset button down and after a while it reboots and shows the default blink program - success! Buuuttt its still not on the list of USB devices, no matter what i do. Unfortunately, then my Teensy just disappeared from the list of USB devices (i'm on Linux).

So i tried to port my real program to the Visual Studio Code way of doing things and had all sorts of trouble but managed to compile it after a few hours. After much struggling i finally got it working with a test program and lo and behold a real debugger with breakpoints and watches! So i was tired of the clunky Arduino IDE and decided to try and get a proper debugging scenario working with GDB and PlatformIO under Visual Studio Code.
