I am using Kinetis K64 in multiple projects with KDS3.2 and KSDK1.3 without many issues. For UART applications (modbus RTU) we have found the UART_DRV_SendDataBlocking and UART_DRV_ReceiveDataBlocking functions to work well under FreeRTOS.
Recently we tried to use the EDMA version of these functions without success while trying to configure them with Processor Expert.
Is there any documentation describing how this can be done? Or is there a limitation of KDSK1.3??
