Application for reading and writing to memory of ARC700 processors using JTAG-HS2 cable

[Jagbandhu Sahu]

hi,

I have a ARC700 microcontroller board. I need to develop an application which can read and write RAM memory of the controller using Digilent HS2 JTAG cable.

 

Any help would be appreciated.

Hi @Jagbandhu Sahu,

I have reached out to my co-workers to see if they have any input for this thread.

cheers,

Hi @Jagbandhu Sahu,

I do know that the JTAG-HS2 works with the ARC processors. Unfortunately we do not have any information about the ARC processor. You will need to contact Synopsys for assistance in developing an application which can read and write RAM memory of the controller using Digilent HS2 JTAG cable. 

thank you,

Jon

Thanks for the information. I am already in touch with synopsys regarding this.

Also, I want to use JTAG-HS2 cable in a chamber at 85C temperature for duration of 170 hrs approx. 
Will it sustain for the above requirement?

HI @Jagbandhu Sahu,

I do not see an issue with the JTAG-HS2 operating at 85 Celsius. I have reached out a more experience engineer to see if the 170 Hrs duration would be an issue.

cheers,

Hi @Jagbandhu Sahu,

Unfortunately we did not test the JTAG-HS2 for this length of time and do not have any metrics for this. The engineer that would be conducting this test is out until November 10th and then there would be the 170 Hrs for the test. If you are still interested in knowing this information please let us know.

cheers,

Jon

Hi Jon,

Thanks for replying. My requirement is to test around 100 ARC processors in a chamber at around 80C for 170hrs and collect the logs generated during the tests via HS2 JTAG cable. So, 100 HS2 JTAG cables will be connected to ARC processors inside the chambers.

I have application for retrieving the logs via HS2 JTAG cable.  But before running at 80C, I want to be sure that HS2 cable can withstand that temperature for a given period of time.

Also, I will run this test multiple times, so I want to know its endurance(no. of test it can run without damage.(1test = 80C temp for 170hrs))

 

Thanks

Hi @Jagbandhu Sahu,

After doing some more research I learned that we do not test these conditions with our products. Unfortunately, we would not be able to guarantee the JTAG HS2 working in these extended conditions, but you're welcome to test this for yourself.

thank you,

Jon

Hi Jon,

According to HS2 JTAG cable specs what is the maximum temperature it can withstand?

Hi @Jagbandhu Sahu,

We are waiting for some more details on the temperature specifications for the JTAG HS2 from our senior engineer. Thank you for your patience.

thank you,

Jon
