MSP-GANG: Cannot Open target device MSP430F427 while using MSP-GANG DLL

Fiyinfoluwa Owolabi

Part Number: MSP-GANG
Other Parts Discussed in Thread: MSP430F427

Tool/software:

I am using the MSP-GANG dll to program and write IDs to the MSP430 F427 device. I am able to connect, erase and program the target but when I try to enter interactive mode with Interactive_Open_Target_Device I get Err 23 TARGET_DEV_INIT_ERR. I am trying the SetGangBuffer() and Interactive_Copy_GANG_Buffer_to_FLASH() to write the ID and then Interactive_ReadBytes() to read and verify the ID is written correctly. I am unabel to get to these steps however as Err 63 -(Target not Open) is shown due to previous error. For context, I am creating a C# application to be used within a .NET module in TestStand 2019, and connecting to the target device with JTAG.

How can I resolve this issue (i.e. Do I need to set certain configs before sending Open target?)/can I use another method to write and read from the ID location.

It shows the documents and exmaple for your reference.

Hello Sal,

I read through the thread and it agrees with some other that I saw, I have tried setting the CFG_TMP_CUMULATIVE_ST_EN config to 0 before sending the Interactive open target but still does not work.

I used the Cpp_Interactive example and tried to open the target and get the following response seems I still need to set something? Not sure what I am missing.

Hi Fiyin,

I check the latest GANG GUI below:

It looks quite different with your shared version. Is the GUI developed by yourself and in the background you call the API defined in .dll files?

Hi Sal,

No this GUI is used in the Interactive_cpp example that is mentioned in the thread you suggested above, I just ran the solution to test the implementation and it still is not able to open the device.

Many thanks,

Fiyin

It support interactive mode, and you can click on the "READ" option to open the target.

Please let me know if it works for you. I used to play with this GUI and read back the msp430 device.

Hello Sal,

Apologies for the delayed response I missed your message.

Yes, when I use the GUI I am able to open and read from the target.

However my problem is opening the target using the MSP-Gang.DLL, when I attempt to open the target I get the error mentioned above, and similarly when trying to use the example code. Is there a problem with interactive mode? Or maybe my chip - MSP430F427 - is not supported?

Many Thanks,

Fiyin

Hi Fiyin,

Unfortunately, I do not know how the dll works and its grammar.

I will keep the thread open to see anyone could help on this issue.

One expert on MSP-GANG within my team is OOO till next week, I will also forward the thread when he come back to office.

B.R.

Hello Sal,

Thank you for keeping this open and for your help so far.

While waiting for your colleague can I ask if you know whether the older Gang430.dll works with the new programmer. Some of the examples suggest it does but it does not seem to communicate with the programmer.

Many Thanks,

Fiyin

Hi Fiyin,

I have no additional information. The older .dll file should work when you maintain the same software version in MSP-GANG.

Hi Fiy,

https://www.ti.com/lit/ug/slau358q/slau358q.pdf?ts=1752553171780&ref_url=https%253A%252F%252Fwww.google.com%252F

The MSP-GANG user guide above should be able to provide you with more detail regarding the GUi and its offering. I would recommend going through this first.

Thank you,

Hi Fiyin,

Can you show what the flow you call the open target in your C# code? So that we can help take a check on your process flow.
