CCS/DRV8301-HC-C2-KIT: problems seeing source code in debug perspective

I notice that I CAN load, see source and execute the InstaSpin GUI project.

The only difference I can ascertain is that this project requires the DSP flash

I have tried manually erasing the flash to see if that encouraged that PM Sensorless project to work - but to no avail

Thanks for any advice.

Best regards,

Hi Richard,

If you go to Run->Load->Load Program and load the PM_Sensorless application that way, does it go to main()? If you hit the Reset and Restart buttons does it go to main()?

Those lines where you're stuck are in the boot ROM. You can step through the boot ROM by going to Run->Load->Add Symbols... and specifying the file below.

controlSUITE\libs\utilities\boot_rom\2803x\2803x_boot_rom_v1\Release\TMS320x2803x_boot_rom_Gold_V1.out

If CCS complains about not being able to find the source, you can point it to the 2803x_boot_rom_v1\source directory. Being able to see the boot code may help you debug why it's getting stuck there. From the addresses you mention, I can tell you're specifically stuck in WaitBoot.

Thanks Whitney

resetting does not take me to main, nor does restarting

if I try run->load->PM_sensorless 

the control buttons indicate that the code is running but if I suspend the code pointer is up in the boot rom area

in the console it shows: C28xx: AutoRun: Target not run as the symbol "main" is not defined  

from loading the boot rom source I can see that I ultimately end up in 

 _ITRAPIsr   
;-----------------------------------------------
;-----------------------------------------------
; This is the ITRAP interrupt service routine for
; thet boot ROM CPU vector table.  This routine
; would be called should an ITRAP be encoutered 
; before the PIE module was initalized and enabled. 
; 
; This module performs the following actions:
; 
;     1) enables the watchdog
;     2) loops forever
;-----------------------------------------------

_ITRAPIsr:
    SETC OBJMODE        ;Set OBJMODE for 28x object code
    EALLOW              ;Enable EALLOW protected register access
    MOVZ DP, #7029h>>6  ;Set data page for WDCR register
    MOV @7029h, #0028h  ;Clear WDDIS bit in WDCR to enable Watchdog
    EDIS                ;Disable EALLOW protected register access                             
    SB 0,UNC            ;Loop forever   

where it loops for ever

I've not changed anything in the linker script or map so I am confused as to why this is not working

In trying to load the different programs and symbols I appear to have encoutered an error 

C28xx: Error connecting to the target: (Error -1133 @ 0x0) Device blocked debug access because it is currently executing non-debuggable code. You may retry after the device has had time to enter debuggable code, or you may cancel, disable realtime mode, and then attempt to connect. (Emulation package 6.0.628.3) 

the confusing thing about this one is that once I cancel I can see no way to disable realtimemode?

Any suggestions would be great!

Thanks

If you pull up main() in the Disassembly window, do you see valid code loaded there? Will it let you right click and select move to line? If the code isn't loading properly and it's jumping to an invalid instruction that could explain the ITRAP.

I tried loading this example myself and didn't have any issues.
