CCS/TMS320F28377D: C2000™ microcontrollers forum

Part Number: TMS320F28377D

Tool/software: Code Composer Studio

Hello.

I want to update program by SCI line.

I made two programs that sci_flash_kernels using FLASHA(0x080000) and main program using FLASHB(0x082000).

I referenced the TI controlsuit/F2837xD_sci_flash_kernels.

I set flash boot mode.

If my sci_flash_kernels program doesn't receive 'a' code for 20 sec, I set an entrypoint 0x082000 for FLASHB.

My main program works that LED blink and send "hello" through SCI every 0.5 sec continuously.

A problem is the main program does not work perfectly. The program blinks LED. But does not send "hello" data perfectly.

The "hello" characters changes other ascii characters. (#1)

I checked my FLASHB program using JTAG debuger. I connected JTAG debuger and only update FLASHB.

The program works well using JTAG debuger. But If I reset the program, the program works like (#1).

1) What do I check to solve this problem?

2) I insert command link files the SCI_kernel and the Main program. Please check My linker file.

                                                      <sci_kernel command linker file>

                                                                    <main program command linker file>

In spite of my bad English skill, thanks for reading . I'll wait for reply.
