I understand some driver changes are required. Under VDSP we had a UART on a BlackFin 561 working in chained mode with 256 byte buffers, and were using the ADI_UART_CMD_ENABLE_AUTO_COMPLETE to end receive on a special character. I don't see this capability in CrossCore... Am I missing something? This was very helpful, since we don't want to wait for an entire buffer to fill if the special character can close out the reception first.. Thanks for help!
