CC2642R: Errors from bootloader for COMMAND_DOWNLOAD command.

Here is the Application Report for reference: https://www.ti.com/lit/swra466 

Have you evaluated the SblAppEx?  It would be worth confirming that this software solution works first, then compare the UART communication with your implementation.  Perhaps you could include the structure of your CMD_DOWNLOAD as well, the packet format is included in Section 10.2.3.2 of the Technical Reference Manual: https://www.ti.com/lit/swcu185 

ucCommand[0] = <size=11>;
ucCommand[1] = <checksum>;
ucCommand[2] = COMMAND_DOWNLOAD;
ucCommand[3] = Program Address [31:24];
ucCommand[4] = Program Address [23:16];
ucCommand[5] = Program Address [15:8];
ucCommand[6] = Program Address [7:0];
ucCommand[7] = Program Size [31:24];
ucCommand[8] = Program Size [23:16];
ucCommand[9] = Program Size [15:8];
ucCommand[10] = Program Size [7:0];

Thanks.  The issue was the Program Size, not the address.

On a related note, is there a tool within CCS that will convert the intel hex format output file to a binary file suitable for downloading?

Thanks.

On inspection, armhex utility will not work.  It places the CCFG immediately following the application code, so it is not located properly.  I have tried to add the fill and linkerfill options to the command, but am not able to get the CCFG data properly put at the end of flash.  Is there another tool that will create a binary file suitable for downloading from the .hex or the .out files?
