Generating hexfiles for teensy 4.1 with MCUXpression i quite simple and works out of the box without any changes of the linker skript. You will find some ready to use examples here.

Meanwhile I have a RT1060 evaluation board here on my desk which has a SWD debug port on board. So I can develop on the eval board and finaly download a hexfile to the teensy board. My first attempts were quite...

According to this idea, maybe you can omit the separation to the MKL02. It would be worth a try to connect PTA1 to ground without any trace disconnection. As long as the MKL02 is held in reset, all ports are inputs....

Hmm, but it's only possible when start with JTAG. As far as I know Paul did burn the flag to disable SWD, right? So it seemes to be inpossible to start with SWD after reset.

Thank you very much for the detailed explanations. I understand you very well and I would agree, but I'm just curious about the specific solution for this bootloader. As far as I know the i.MX controller has different...

I'm profosisional developer and did look for a small board with ethernet and high speed usb. So I was happy to find teensy. Maybe teensy is a gread produkt but I would like to undestand how it works in in junktion with...

I' very disappointed. From my point of view I freely avaibale SWD or JTAG connecter is a must have. The board has a very powerfull MCU but without a debug connector not usable for me.
