CCS/TMS320F28377D: Data Verification Error

Eric Din71

Tool/software: Code Composer Studio

I have been coming across strange data verification errors. CCS output pasted below. The odd thing is that I am able to successfully program one revision of my boards and not another, although there was no design change between board revisions. I have checked pull-up/down resistors on programming pins and boot mode pins, and there are no differences between the boards.

Part markings on the successfully programmed MCUs are : YFC-88A383W

Part markings on the unsuccessfully programmed MCUs are : $4C-97A411W

Could the batch of MCUs have anything to do with the issue? Anything else in hardware that could impact?

C28xx_CPU1: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.

C28xx_CPU1: File Loader: Verification failed: Values at address 0x82000@Program do not match Please verify target memory and memory map.

Hi Eric,

Have you seen the below article?

http://dev.ti.com/tirex/explore/node?node=APy2XbLelxyqBB2Yz0WR.w__FUz-xrs__LATEST

It covers many of the scenarios for your error.

Is the same exact CCS installation and target configuration file used for both the working and non-working boards?

Thanks

Hi Ki,

Thanks for the quick response. I have seen that article, and I was able to launch the target manually to access the memory map, shown below. The error is 0x82000@Program. Are the correct attributes below?

I can confirm that it is the same exact CCS installation and target configuration file used in both working/non-working boards. I have two boards powered; I can click "CCS Debug" and program one but not the other.

Thanks,

Eric

That is correct as 0x82000 is flash memory (FLASHB).

I just used CCSv9.2 to flash a program at that address to CPU1 of my F28377D controlcard.

Since you are using the same tools environment between the working and non-working targets, it does seem like an issue with that specific batch of devices.

I will bring this thread to the attention of the device experts for more assistance.

Thanks

Thank you Ki. When can I expect a response? We are on a tight timeline with this, hoping to flash our 50 boards and get them into a project we're working on... this seems like a pretty big delay...

Another piece of information: Despite being able to manually connect to the target and see all 0xFFFF in flash, I am unable to erase or confirm blank device through the "On-Chip Flash" menu. I have been able to follow the same process with an existing board and successfully erase.

It sounds like there is some issue with interfacing with the flash on those batch of devices. I'll make sure to bring this thread to the attention of the device experts.

Eric,

Please refer to this FAQ regarding a PCN(Product Change Notification) we issued and the needed actions required on your part in order to program the devices referenced. I will also assign this to the C2000 flash expert in case there is follow up needed.

Best,
