trouble porting dev_cdc_vcom_lite example to MK22DN512

[audio_guy]

I can't get the dev_cdc_vcom_lite example from twrk21d50m to work on our hardware with MK22DN512. I tried running the version for frdmk64f and it works OK. Using USB snooper I see (for our system):

whereas for frdmk64f I see:

the code is virtually identical but our system does not send device descriptor. Any ideas?

thanks

Hi,

i think you can download the SDK package absed on MK22, in this way, you do not need to port code from K64 to K22.

you can download sdk2.0 based on MK22 from the website:
