I use the demo code evkmimxrt1064_dev_cdc_vcom_lite_bm on the RT1064 EVK. The code works fine as the data echo back from the input char. Now I want to change it to send the input to another place instead of sending it back to the USB port. After code modification, I don't get the USB interrupt anymore. except the first input char (I have a breakpoint at USB_OTG1_IRQHandler()). If I send the data to other place and back to the USB port then I can get the interrupt for every char.
Is there a register that need to be reset to reenable the interrupt in
USB_DeviceSendRequest(s_cdcVcom.deviceHandle, USB_CDC_VCOM_BULK_IN_ENDPOINT, s_currSendBuf, size);
?
Thanks.
