I used the example from Freescale USB Stack v4.0.3\ProcessorExpert\Examples\Device\CDC\USB_CDC_DEVICE_JF128_PEx to make a CDC device with a TWR-MCF51JF128.
The example work fine when TWR receive a byte from UART and send to USB using
status= USB_Class_CDC_Interface_DIC_Send_Data(CONTROLLER_ID, g_curr_send_buf,size);
but when size =16 no one byte is sent.
status result is USB_OK .
g_curr_send_buf seems set in queue
Callback function returns 216 bytes sent", but nothing is transmitted by USB
Reception works fine with 16 bytes.
Anyone knows what could be happening?
I need send AES encrypted data in 16 bytes blocks
