MSP-GANG: hwo to upgrade to MSP_GANG from GANG430

Hi Yale,

That error could be due to hardware connection issues. Can you try programming the board once with the MSP-GANG GUI and see what the result is?

While using the GUI, can you also have them check the gang software revision and firmware versions?

Best Regards,
Brandon Fisher

1.Use MSP-GANG GUI, use Interactive mode, it can programming the board.

2.gang revision is below:

That indicates to me this is probably not a hardware issue. Can you have them download and try the latest version of the MSP-GANG DLL and GUI?

https://www.ti.com/tool/download/MSP-GANG-SOFTWARE

It should be 01.03.07.00.

Is their application written in C or something else? Can they share which regions of memory they are trying to write on the device, are they locking JTAG/SBW as part of their code?

Hi Brandon,

The follow up from the customer:

We must use VB6.0 upgrade to MSP-GANG from GANG430, there's 2 solution:

1. For MSP-GANG.pdf 4.1 ,use wrapper , copy GANG430.dll, GANG430.ini, MSG-Gang.dll to working directory. We can only program 1 times, then 2 times

LCD display target init Failed.

2. For software examples c#,C , re-write by VB6.0, can loadImage, can download and get a correct result, but there's a error Runtimes'49', Bad DLL Convention. 

Private Declare Function MSPGANG_GetProgressStatus Lib "MSP-Gang.dll" (lpData As Any) As Long

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal nLength As Long)
Private Declare Function VarPtr Lib "MSVBVM60" (var As Any) As Long

Dim pOutputArray As Long
Dim tempBData As Byte
Dim outputArray(0 To 51) As Byte
pOutputArray = VarPtr(outputArray(0))

VGangGetResult = MSPGANG_GetProgressStatus(pOutputArray) An error will be reported here.

If VGangGetResult = 0 Then

CopyMemory outputArray(0), pOutputArray, 52
tempBData = outputArray(10)

So, please help! Thank you very much!

2. You're right. It should be mismatch the argument about lpData which is void *pointer. Anyway I cannot find what is correct to match void * in C#. We use vb6.0 in Windows10 OS and copy MSP-Gand.dll to working directory.

for example, we need *** parameter to check the result value of  current channel. As 3th channel, the result value is  00100000 , we can get it. There'r a Bad DLL Convention error after execute download function  because we need call MSPGANG_GetProgressStatus(void *lpData) function.  I am not sure which is conflict  with some VB syntax 

4. Although we can download success with c# example, but both of red light and green light is on. But is not in GUI interface, only green light is on.

Thank you so much for your help!

HI, Brandon

About use VB6.0 and MSP-Gang.dll, MSPGANG_GetProgressStatus(void* lpdata) Here is a pointer to structure by Reference document , in C#  example, it's a byte*, in C example, it's a pointer to union. But we use Any in VB6.0, there's a error:

Dim pOutputArray As Long
Dim tempBData As Byte
Dim outputArray(0 To 51) As Byte


pOutputArray = VarPtr(outputArray)

VGangGetResult = MSPGANG_GetProgressStatus(pOutputArray)   Error is here.

Now, we add a "On Error Resume Next" before call download function,  Run Debug mode, it can download. but Make exe file,  This app interface Exit.

Should be there's different between MSPGANG_GetProgressStatus(void* lpdata) and GANG430_GetGangResult(void* lpdata), Please help  me !
