Your device configuration ccxml file doesn't seem match with device you are trying to connect to. Please ensure both of them match.

Hi,

Are you using a proper linker command file for your device? Are you able to connect to the device target in CCS successfully? If so, could you connect and check some of the flash locations using the memory browser?

Is there a possibility that the device was interrupted while programming/erasing the flash potentially causing the device to get locked?

Best,
Kevin

Hi,
Please help me. The issue which we are discussing arose after many debug sessions. What might be the cause. I didn't disturb any setting on the micro controller before the issue arose.
1. Are you using a proper linker command file for your device?
Yes
2. Are you able to connect to the device target in CCS successfully?
Yes I the connection was fine.
3. Is there a possibility that the device was interrupted while programming/erasing the flash potentially causing the device to get locked?
I think "No".
4. Could you connect and check some of the flash locations using the memory browser?
I don't know how to do this could anyone please help me.

Hi,

Steps to check #4 within CCS below:

1. Open the Target configuration window (View --> Target Configurations)
2. Right click your device Target Config and select Launch Target Config
3. At the top, under the Debug window, right click the Debug Probe_0/C28xx and connect to target
4. Open the Memory Browser window (View --> Memory Browser)
5. Type in and search addresses located in flash (starting at 0x3F 0000 for F28027) and check the values

Make sure all steps of the above succeed. The data should be all FFFF if the flash is erased. Checking the values in Flash Sector A is the most important, starting at address 0x3f 6000.

Best,
Kevin

Hi Kevin,

Thanks for the suggestion. I followed the procedure that you have explained in the previous post.

Hi,

Can you check what is at address 0x3F 7FF8 to 0x3F 7FFF for me? This is the location of the 128-bit password for the Code Security Module and should not be programmed to zeros. If it is somehow, the device is permanently locked.

More info on the CSM can be found in Section 2 of http://www.ti.com/lit/sprufn3

If this isn't the issue, it may be that some of your functions are running from Flash when they need to be copied to RAM and run from it instead. ISRs for example should be copied and run from RAM.

Best,
Kevin

Hi kevin,

Thanks for your reply. From address 0x3F 7FF8 to 0x3F 7FFF the values are zeros. What might be the problem??

Hi,

I believe the device is permanently locked and not able to be recovered unfortunately. This must have occurred at some point when messing with the flash.

You can try running the depletion recovery or erasing all flash sectors within CCS, but I don't think that will fix it.

Please see: e2e.ti.com/.../208010
