TMS320F280049: Trouble Setting Breakpoint with the Action "Remain Halted" at 0xc0d4

Shengnan Li

Part Number: TMS320F280049

I encountered this problem when program a new customized board.

Memory Map Initialization Complete
C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...

C28xx_CPU1: Warning: Failed unlocking device (zone 2) after reset.
C28xx_CPU1: Trouble Setting Breakpoint with the Action "Remain Halted" at 0xc0d4: (Error -1066 @ 0xC0D4) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 9.5.0.00143)
C28xx_CPU1: Breakpoint Manager: Retrying with a AET breakpoint
C28xx_CPU1: Error executing PLL configuration algorithm. Operation cancelled. (0x0)
C28xx_CPU1: Perform a debugger reset and execute the Boot-ROM code (click on the RESUME button in CCS debug window) before erasing/loading the Flash. If that does not help to perform a successful Flash erase/load, check the Reset cause (RESC) register, NMI shadow flag (NMISHDFLG) register and the Boot-ROM status register for further debug.
C28xx_CPU1: File Loader: Memory write failed: Unknown error
C28xx_CPU1: GEL: File: C:\Git\Digital_POL\buck_nonpowerSUITE_F28004x\RELEASE\buck_nonpowerSUITE_F28004x.out: Load failed.

Some more details:

1. debugger communication is successful

2. xrs pin is 3.3V

3. GPIO23 and 32 (boot mode pins) are both pulled high

4. VDD output 1.2V

5. another board of the same patch works fine, but i noticed the power drawing from this specific board is lower then the working board.

Thanks!

Shengnan,

is the device locked? The first highlighted output indicates that its locked.

Secondly i assume you meant GPIO24 and 32, is that correct?

Cody

Cody,

Thanks for the response.

what does the device is locked mean? how to unlock?

It is a typo, GPIO24 not 23.

I think this post covers it well: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/513103/tms320f28075-unable-to-program-flash

Of course that is a different device, the same logic applies. See the F280049 datasheet for the correct addresses to read.

Hi, Cody,

Since there is an error when loading program, I can't proceed to debug mode. when view memory, it is empty. how to view memory browser without get into debug mode? Thanks!

go to View->target configurations

In the target configurations window you can create and launch a target configuration.

If you have not created one yet, right click in the window and select "new target configuration" and select the emulator and device that you are using.

Once created you can right click on the target configuration and then click "launch selected configuration".

This should setup CCS and the emulator to be ready to connect to your device.

Next navigate to the "debug" window and right click on the C28xx core and select "connect".

This will connect you to the device and allow emulation access, if you then wish to load code, that is possible from here as well. But as you indicated above you are seeing issues when attempting to load code.

Cody

When right click on the target file, can't find 'launch selected configuration'

Please attempt this in the "target configurations" window, it is on the far right side of your screen. Please note that there are two folders, expand the "projects" folder and you should be able to see your desired target configuration.

Is this secured or not?

Possibly, can you now read any of the flash memory addresses? Are they showing as all FFFF or 0000, if yes then the device is likely secured.

You can also directly check the UNSECURE bit in Z1_CR and Z2_CR registers to be more certain.

Problem solved. It has something to do with xrsn.

Thanks for walk me through a lot of stuff.
