RE: LAUNCHXL-F28P65X: Serial Flash Programming Fails "Attempting autobaud to load kernel"

Other Parts Discussed in Thread: LAUNCHXL-F28P65X, C2000WARE

Hi Matt,

I was able to get the Serial Flash Programming exampled working without having to debug and step through the boot ROM code. 
Now I have moved on to porting the Live Firmware Update With Device Reset on C2000Tm MCUs example to the LaunchXL-F28P65X.

I am close to get it working, but it does not seem to be booting into my download firmware correctly and I want to step through the Boot ROM code after a CPU Reset.

I am following your instructions from above.  

I added the Symbols from "C:\ti\c2000\C2000Ware_5_04_00_00\libraries\boot_rom\f28P65x\rev0\rom_sources\cpu1\ccs_files\Release\F28P65x_CPU1_ROM.out"

I added the Source Path.  "C:\ti\c2000\C2000Ware_5_04_00_00\libraries\boot_rom\f28P65x\rev0\rom_sources\cpu1\F28P65x_ROM"

After executing a CPU Reset, my step pointers are located here (in code file cpubrom_boot.c and in the Disassembly window.

If I do Step Over (F10) two times, the pointers are here. 

This is on a comment line.  This does not seem correct.  It does not seem to be stepping through the correct source code.

Can you help me with this?  Am I doing something wrong.

Thank you,

Rob McCullough

    Hi Rob,

    That is expected. The boot ROM symbol files in C2000Ware don't always match the actual ROM (they aren't always to date with each other). You can use the symbols to safely estimate where the device is executing the ROM.

    Best,

    Matt
