New to the teensy eco system. Got a T4.1.
I have one thing to confirm before moving on with it. We need the ability to update the firmware without using a PC / laptop. In the R.R. industry this is forbidden to install a tool on a PC without jumping through hoops to get it certified.
Thus I need to create a portable programmer. A simple handheld device with a pushbutton.
Can one T4.1 be connected to another and update the firmware ?
I.E. the first T4.1 with the .hex file on the uSD card will read it and flash the second T4.1
Is a solution like this or a device already out there ?
