Hello all,
We are designing a little product based on the MK20 and Teensy boards. We are currently purchasing bootloader ICs from PJRC and installing them onto our own boards.
We were getting ready to place a first bulk order but Digi-Key is out of stock of the MK20DX256VLH7 chips that are needed by Teensy system. It seems out of stock from most vendors for a month or two.
We were wondering about our options for moving forward asap.
I see that the MK22 variant, that happens to have more flash space, is available. I believe it is also pin compatible. (MK22FX512AVLH12 & MK22FN1M0AVLH12) How different could the peripherals be?
Does anyone know if the Teensy bootloader IC will work with the MK22 directly - even if it doesn't let us access all of the flash?
Is there any possibility of getting a version of the Teensy bootloader that does support the MK22?
If we can't use the Teensy bootloader IC, we do happen to have SWD available on the board and could possibly program like that. I wonder how much hardware initialization the Teensy bootloader software does and how specific it is to the MK20DX256VLH7. I wonder if we can just take a hex file from Teensyduino / platformio and load it onto the devices ourselves...
Thanks!
