TMS320F280049C: UNIFLASH, how to unlock?

Brandon Yee

Part Number: TMS320F280049C
Other Parts Discussed in Thread: UNIFLASH

Hello,

I was programming my 280049C using the XDS110 without issue until I got the following error:

Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible, and power-cycle the board. If error persists, confirm configuration and / or try more reliable JTAG settings (eg lower Tclk)

I downloaded Uniflash 6.3 and looked inside the quick start guide but couldn't find anything on unlocking. Within Uniflash, I see the following but I am unsure how to proceed.

Thanks,

Brandon

Hi Brandon,

Did you check your map file to see if there is anything mapped to the password locations? Maybe something got mapped to that location - if yes, the password might have been programmed in previous program load iteration.

Thanks and regards,

Hi Vamsi,

Where is this map file located? For context, I've been programming my device using CCS not Uniflash.

Thanks,

Brandon

Hi Vamsi,

There is no .map file in my project.

Thanks,

Brandon,

In the project linker settings, what do you see for the -m option?

Hi Vamsi,

My board is no longer stuck in the locked state and I no longer require assistance.

Thanks,

Brandon

Brandon,

Glad to know that. How did you resolve this? Is this a board issue then?

Thanks and regards,

I'm not sure, as it seemed to resolve itself the day after I posted this issue. I've been testing the board since while keeping an eye out for a reoccurence.
