Hello, I'm trying to get UART working on the k22 FRDM board and have been having some issues. I have been following the SDK 2.0 API Reference Manual (Kinetis SDK 2.0 API Reference Manual: UART Driver ) and trying to implement either the polling or the interrupt methods. Both examples won't work, I'm using a slightly different sdk but the process of setting up UART should be similar (I'm using SDK_2.3.1_FRDM-K22F). I think there is something I am not initializing or setting up correctly but I am not sure. I keep getting this error: Error: CMSIS-DAP: Read Error (0x04) Error: Failed to read memory at 0xd36c0850
Please let me know how you connect the FRDM-K22F, the P&E OpenSDA or Segger J-Link? Would you mind to give as much information as what you had done, that will much helpful.
