I recently got a FRDM-MKL26Z dev board and I'm having trouble getting USB up and running.
I took some code from the Teensy repository ( cores/teensy3 at master · PaulStoffregen/cores · GitHub ) and the USB code from this project ( kcuzner/teensy-oscilloscope · GitHub )
However, when I compile and flash the board the only USB interrupt that fires are 'reset' and 'sleep'.
I was wondering if someone could look at my code, and see if anything looks wrong.
I guess the main points of interest would be the following:
init_clocks_ref() : frdm-mkl26z/mkl26z64.c at master · jgouly/frdm-mkl26z · GitHub
USBOTG_IRQHandler() : frdm-mkl26z/usb.c at master · jgouly/frdm-mkl26z · GitHub
Any help or guidance would be great, and if you need more information, let me know!
This question seems similar to USB k20_100: no TOKENDNE interrupt. Please help. but it was never resolved.
