Strong ZHANG

Part Number: TMS320F28076
Other Parts Discussed in Thread: UNIFLASH

Hi Expert,

My customer face an issue that fail to program code with DCSM by Uniflash for F28076, it showed verification failed at address 0x84010 which is flash address,

if they did not use DCSM, then they can program the code by uniflash successfully.

if they use CCS tool, there is no this problem and be able to program the code with DCSM.

Any suggestion for this?

Hi Zhang,

Can you please check if customer is using latest Uniflash version ?

As per the error message, look like that location is secure and Uniflash is not able to read the content because of that but customer must have provided the password in Uniflash GUI so it should unlock the device using the password and then try to verify it. I am looping in our Uniflash expert also to look into this.

Regards,

Vivek Singh

Hi Zhang,

Can you let me know if the customer is clicking on the 'Verify Image' button after program load?

This command is a standalone verification step, and unfortunately does not unlock the device before it starts the verification. A workaround for this is to change the setting to keep the core connected after an operation (by clicking the core name in the top right corner of the GUI), go to 'Settings and Utilities' to unlock the device, and then click on 'Verify Image' (the device should still be connected and unlocked in this case).

This is a known issue with the tool and is documented in the release notes (https://software-dl.ti.com/ccs/esd/uniflash/docs/v7_0/release_notes_7.0.0.html#known-issues).

Please let me know if this works for the customer.

Thanks,

Ricky
