FLASH-PROGRAMMER: The Channel 2 of C2000-Gang Programmer cannot be setted to download sucessfully

Hi,

Which device are you trying to program using GANG?

For faster support, please contact Elprotronic technical support team directly at support@elprotronic.com .

I notified this issue to Elprotronic.

Update: I spoke to Elprotronic. They did not understand the chinese email thread correctly. Hence could not help on time. Please expect a reply today.

Thanks and regards,

Hi,

The Gang Programmer program all targets simultaneously (in parallel). You can select what target is verified, but does not means that other target does not take the commands the same as sent to active channel. Means - it is not possible to select e.g. target 2 and  disable targets 1,3,4,5,6, then enable target 1 and disable  all other targets and send e.g. command Erase. That can erase all of them. We provide gang option commands that can provide unique data to each targets, but commands can be the same to all targets with different data to each target e.g. for saving calibration data or serial number unique to each targets. Only enabled targets are verified. All other response from un-market targets are ignored. 

Please let me know if you have any questions.

Hi, Vamsi

We are trying to program TMS320F28335 using C2000-Gang.

Thanks

Hi,Gregory Czajkowski

Thank you for your reply sincerely.

We are trying to program two TMS320F28335  chips that we called one the main chip and the other one the assisted chip. Do you mean that we can download the respective program of the main chip and the assisted chip using channel 1 and channel 2 at the same time?

Thanks and regards,

WangCaixia

Hi WangCaixia,

It is not possible at the same time. You should download project one and program target 1 with disconnected target 2. When finished - disconnect target 1, connect target 2 and download project 2 to programmer and run it. If you would like to download different programs to different targets simultaneously, then you need two programmers and control them from one PC. You can use our FlashPro2000 (in your case - 2 pcs) and control up to 64 programmers simultaneously via our DLLs. We do not provide that option for C2000-GANG.

Let me know if you have any questions.

Hi,Gregory Czajkowski

Add some information:

1、The version of our C2000-Gang is as below. "Serial number" , "API firmware"  and "Boot firmware" cannot display normally. Please help us to correct them.

2、When we use GUI software to download certain program to target from channel 2, the result is  PASS; But when we use dll to download the same program to the same target from channel 2 with the interface C2000GANG_SetConfig, the result is FAIL, and we get the error return from dll.  We want to solve this problem.

Looking forward to your reply sincerely.

Thanks and regards,

WangCaixia

Hi Gregory Czajkowski,

Thank you so much. Actually,we control the download process of these 2 targets as your description:"You should download project one and program target 1 with disconnected target 2. When finished - disconnect target 1, connect target 2 and download project 2 to programmer and run it".

But we get the error return from DLL. Please refer to my other reply mail.

Thanks and regards,

WangCaixia

You should check drivers and connection. When label is not displayed correctly, the C2000-GANG will not work.

Gregory Czajkowski

Hi Gregory Czajkowski,

Thank you so much.

The drivers we used are provided by TI engineer:http://content.elprotronic.ca/C2000-GANG-1v10200-Setup.zip.

Would you please provide the correct drivers ?

Thanks and regards,

Wangcaixia

Hi,

Software is correct. I was talking about USB driver. Please check if the programmer is detected under Device Manager.

Regards,
Gregory Czajkowski

Hi Gregory Czajkowski,

We use RS232 to control C2000-Gang not USB, and we can see COMXX under Device Manager.

Looking forward to your reply.

Thanks and regards,

Wangcaixia

The USB drive is also seen as the COM port (like RS232). But if you would like to control two programmers then you should set the commands separately to two programmers under com-A and com-B and control them from the top application. Then you should create multi- thread applications if more that one programmer is connected. Otherwise you cannot send at the same time commands to many programmers. You can use application without multi-thread and switch port in your application  every time you want to send command to dedicated programmer via selected com-port, but that would be the nightmare.

Let‘s review our application scheme and communication records.

There are two TMS320F28335 chips on target board. We want to download the program to chips by C2000 Gang. We can control the connection status between 14pin and TMS chips by electric relay. So we can download one chip and then the other, that means we execute the download process in serial mode not parallel mode. C2000 Gang is connected to PC by RS232 not USB. The download process is as below.

Now we have two problems:

1、  When we use GUI software to download certain program to target from channel 2, the result is  PASS. But when we use DLL to download the same program to the same target from channel 2 with the interface C2000GANG_SetConfig, the result is FAIL, and we get the error return from DLL, the error code is “MCU device init.” .  We are confused that there are different results from GUI software and DLL when using channel 2. The same problem is not happened when using channel 1. Maybe DLL revision is not applicable or exists some bugs. Please help us to analyze this problem and solve it. Or can you send us the latest DLL?

2、The label of C2000 Gang is not displayed correctly, but it can work. How to make the label correct?

Hi,

There is no problem with DLL, because GUI is using the same dll for communication with target. GUI itself is doing just configuration and calling functions via DLL in certain order. Please run the GUI, save configuration file for first setup that works, then make the second setup and run the GUI. Save configuration file with different name. Then in your application run your software, load first configuration, run your sequence, when finished, load the second configuration file and run the second setup from your application via DLL. That should work.

Hi Gregory Czajkowski,

Now we have an application requirement of C2000-gang: we want to load the .C2000gangimage file generated by the local PC into the specified image channel in the memory of C2000-Gang by calling C2000-GANG.dll. But no related functions was found from《C2000 Gang Programmer (C2000-GANG) User's Guide》.

We tried to use C2000GANG_LoadImageBlock() . But there was no input parameter like image file name and path of this function.

So please give us some suggestion.

Hi Wangcaixia

You should use the C2000GANG_ImageFileLoad function. See below syntax in the C2000-Gang.h  header 

//The C2000GANG_ImageFileSave and C2000GANG_ImageFileLoad Save/Load the image to/from file

// Used internally by GUI
LONG WINAPI C2000GANG_ImageFileSave( LPTSTR filename, LPTSTR name, LONG type, LPTSTR passw );
#define BINARY_EXTENTION ".c2000gangbin"
#define IMAGE_FILE_EXT ".c2000gangimage"
// note -> extention in the filename will be removed and added extention as above to the final file name.
// for example file name filename.aabb will create files
// filename.c2000gangbin
// and filename.c2000gangimage

#define PROJ_SEC_UNPROTECTED 1
#define PROJ_SEC_PASSW_PROTECTED 2
#define PROJ_SEC_PC_HW_PROTECTED 3
#define PROJ_LOCK_EN 0x10
// available type in the C2000GANG_ImageFileSave
// type = PROJ_SEC_UNPROTECTED or PROJ_SEC_PASSW_PROTECTED or PROJ_SEC_PC_HW_PROTECTED
// or (PROJ_SEC_UNPROTECTED | PROJ_LOCK_EN) or (PROJ_SEC_PASSW_PROTECTED | PROJ_LOCK_EN) or (PROJ_SEC_PC_HW_PROTECTED | PROJ_LOCK_EN)
//
LONG WINAPI C2000GANG_ImageFileLoad( LPTSTR filename, LPTSTR passw, LONG mode );
// mode -> 0. Other value reserved for the future.

Let me know if that helps.

Hi Gregory Czajkowski,

Thank you for your reply. We will try this function later and inform you the results.

According to your reply, maybe 《C2000 Gang Programmer (C2000-GANG) User's Guide》does not contain all the dll function descriptions. Would you please send me the latest user manual?

Regards,

Wangcaixia

Hi Wangcaixia,

User manual is OK. These two functions was prepared for access from GUI only, because file before write or load need to be provided password options and password name. In load is less critical. These options provided during write should be also provided in the Load option. That is the reason that it was not listed in User Guide. It was concept that image file would be saved using GUI and also loaded from file to image - also using GUI.

Regards,
Gregory Czajkowski 

Hi Gregory Czajkowski ,

We tried C2000GANG_ImageFileLoad function to load a new imagefile to C2000-Gang and then executed the download process, but only the old imagefile was downloaded.

Do you mean that this function cannot be used effectively without GUI？

Actually，we want to load the imagefile to C2000-Gang and then execute the download process using C2000-GANG.dll  called by the PC application independently.We don't want to use GUI.

So is there any way to satisfy the above requirements?

Wangcaixia

Hi,Vamsi

I'm sorry to reopen this post.

I will open a new post next time.

Regards,

Wangcaixia

Hi Wangcaixia,

Since these btwo commands are hidden for regular use, I will provide you sequence for the Load commands via email. Let me know what option yyou are using in the save commands - means password protection option. Then I will provide you sequence for load instruction. Email me your request to my email - see email below.
