Debug F280049C with password

Hi,

As discussed in the other post, I requested our security expert to help you on this.

Thanks and regards,

Hi,

I can not see the values you have programmed for the security setting. Can you please post the values in each fields.

When I use uniflash.

 Everything is default. Set password. select file. load image. ready

In CCS:

Everything is default: like -- in the input fields. Set password in Z1OTP-CSMDSWDx. start debug:

This is the message i got with debug output:

C28xx_CPU1: GEL Output:

C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...

C28xx_CPU1: Flash Programmer: Error erasing Sector 0. FMSTAT value = 1040. Operation Cancelled (0).
C28xx_CPU1: File Loader: Memory write failed: Unknown error

So do I set something else for this to work?

Hi,

Everything is default: like -- in the input fields.

That should not be the case. Can you double check that you are using correct device name in your target configuration file. If It is working in Uniflash but not in CCS then it is not device setup issue but something with CCS and it's setup.

I got 2 boards one protected and the other one not.  If I remove the password in CCS and use the other board it works  fine .

Only when I try to get the protected one working I have problems. So what is the procedure for getting to debug a board that has a password in CCS?

Thanks.

Hi,

Following are the steps.

1. Change the BOOTMODE pin setting to "Wait Boot"
2. power cycle the board
3. Connect to CCS
4. Open Flash plug-in GUI
5. Enter Correct password for Zone1 and Zone2 and unlock the zone.
6. Now debug the device.

Any time you apply reset, device will be locked again hence you need to unlock again.

Thanks Vivek,

I think the problem is in point 4. I don't know what that is. Can you please explain/show where I can find it in ccs.

Thanks.

Hi,

That is below step -

Everything is default: like -- in the input fields. Set password in Z1OTP-CSMDSWDx. start debug:

CCS Debug view -> Tools menu -> On-Chip Flash.

So this is the suggested Flash plug-in GUI?

 point 5 where can I press unlock?

Thanks.

In CCS menu bar (at top) can you click on Tools and under that you'll see Flash GUI. Click on that and use that.

I the on-chip flash option is only available when I am debugging. But the debug section in ended because the device can't be unlocked.

Have you taken care of step #1 and 2 ?

Yes, I can program it with no problem with uniflash.

You have to use the Wait BOOT with CCS to debug it. Look like that is not the case. Please change the boot mode pin setting to "Wait Boot" and then try.

- Reinstalled CCS 9.3

- Switched GPIO 24 on LaunchxL-280049C to on. 

- connect USB

- Debug configuration -> flash settings -> CSMSWD set pasword

- start debug

So can you check yourself that this really works on CCS.

Is there anyone successful with debugging with a locked device in CCS 9.2?

Because I start to doubt in that this works in the first place. also when the password is updated for a new one.

Please provide me information how to reproduce this result. Because I can't.

I'm not so sure that those problem are related, I like to see for myself first.  And I still haven't seen any suggestions how and when there are will be resolved.  So don't close the issue!

Just following up based on the activity in the other thread that Vivek mentioned.  Based on what I know this should be resolved with the updated CCS patch that was linked in the other thread.  Let us know if this is not the case and we can better understand what this issue's root cause is.

Best,

Matthew

First I have to wait to the end of April for I can continue.
