CCS/CC3120: connecting multiple devices simultaneously to Uniflash

Lenio Cacula

Part Number: CC3120
Other Parts Discussed in Thread: UNIFLASH, CC3220SF-LAUNCHXL

Tool/software: Code Composer Studio

My ultimate objective is to connect two or more devices to my computer and be able to program them independently with Uniflash.

While trying to accomplish that, I encountered a problem that I am not sure it is a bug with Uniflash or a step that I might be missing.

Since the new version of Uniflash 4.2.2 does not allow the user to select the COM port, I changed the serial number of one of my CC3220 LP's using xdsdfu.exe. With distinct serial numbers, I can select which board I will open the session in Uniflash. The problem I have is that once I select the board, the option for the CC3220 LP vanishes from the drop down list. Here are the pictures that might make it easier to understand. In the first one you see the 12345678 board I changed the serial number and the other board with the default 00000000. Below those options you can still see the CC3220SF-LAUNCHXL.

I then select either 00000000 or 12345678 boards, and the CC3220SF-LAUNCHXL disappears:

Thus my original question: is this a bug or a step I missed?

Is what I am trying to do possible, e.g., select one of multiple boards connected to my computer with Uniflash?

Thank you!

Lenio,

I see the same thing, but I suspect the filtering takes place due to the fact Uniflash can only be used with CC32xx Launchpads via a Serial (UART) Interface connection, and not via Texas Instruments XDS110 USB Debug Probe.

Your screenshot cuts the bottom of Uniflash's screen, but when you click on one of the top two boards the bottom shows:

If instead of choosing a connection you select the CC3220 Launchpad, the connection automatically changes to:

This is compatible with this Launchpad.

The over arching goal of connecting two boards and flash them using the Serial Image Creator is not possible I am afraid. Either the main Uniflash interface should allow selecting the Serial connection or the Image Creator (an application not originally part of Uniflash) should have the ability to make the UART port selectable. I will file an enhancement.

Regards,

Rafael

Is there any way for the public to track UNIFLASH-965?

I'm also interested in being able to flash multiple CPUs (TM4C1294s) with Uniflash.

You can use the public bug tracking portal:

Search for "UNIFLASH-965"

Thanks

Hi,

You can check its status on the link SDOWP in my signature. This issue is still being internally discussed.

You can flash multiple CPUs if they are attached to multiple Debug Probes. However, Uniflash still does not support multiple CPUs on the same scan chain of a single Debug Probe.

Rafael
