Help for Supporting Multiple Digilent HS2 Jtag adapter

[sreenivasarao]

Hello,

we are having some issue with second adapter. read_memory function returns same value which is already written on previous adapter.

Details:

1) Connected Multiple Digilent JTAG HS2 to same Computer

2) Using our application perform the following operations

 a. perform write_memory/read_memory operation on First Adapter (e.g) written 0x10 at 0xf0011200) and read the value at 0xf0011200

b. Then call read_memory against second Adapter. Instead of zero value, getting same value(0x10)

Our Application uses arcint.h and apidglnt.dll for geting ARC Interface(do like enumerate all Jtag Adapter, Connect to selected adapter then finally do read_memory/Write_memory Operations).

Before connecting to second adapter, it remove existing connected adapter then proceed further.

please suggest regarding this.

it works fine if we do the same thing in MetaWare Software.

 

Thaniks,

Regards,

Sreenivas

Hi @sreenivasarao,

Here is a forum thread that discusses using multiple JTAG devices. This is used with the Adept 2 here. I have reached out to  a more experience engineer about your second question. 

cheers,

Jon

HI @sreenivasarao,

We do not support third party software. We have never used arcint.h and apidglnt.dll. We suggest that you reach out to Synopsys about their software.

thank you,

Jon

Hi Jon,

same issue has been reproduced when I opened FTDI- FT Prog application.

When I connect 2 or more JTAG's, it duplicates the information to all JTAG's.

Attached Screen shot for reference.

 

Thanks,

Deepak

Hi @Deepak Srirama Bairy,

Based on the device output you are using JTAG-HS2's. Is that correct? Please download Adept 2 here and make sure the Serial Numbers are different.  Once you have Adept 2 downloaded I would suggest to look at this forum thread. I have not used FTDI -FT prog. I would also reach out to FTDI about their software. 

thank you,

Jon
