Replacing JTAG-HS3 firmware with JTAG-HS2

[PrasadK 0]

Hello all,

I had recently ordered a JTAG-HS2 cable, but due to some miscommunication with our purchase department, a JTAG-HS3 cable was accidentally ordered. Since I need SPI direct programming feature,  the HS3 cable is of no use to me. Is there a possibility that I can convert this HS3 cable to HS2, so that I can utilize this cable that was mistakenly ordered?

Little details:

FPGA: Xilinx Spartan XC3S50A.

SPI Flash: Adesto AT45DB021D

We use master SPI configuration mode on FPGA and our board does not have FPGA JTAG header. It just has a header containing SPI connections going directly to the flash.

Thank you in advance!

Hi @PrasadK,

I have reached out to another engineer to see if it is possible to change the JTAG HS3 to program SPI ports; I don't think it is readily possible, but I am double checking this.

Thanks,

Hi @PrasadK,

I learned that the JTAG HS3 has a different hardware configuration so it is not possible to get it to work with SPI ports like the JTAG HS2; I don't know when you purchased it but I would recommend that you get the JTAG HS3 returned and get the JTAG HS2 sent instead if you need to program over SPI (which it seems is a requirement for your application).

Thank you,
JColvin

@JColvin, Thanks for a quick reply. I will get the cable changed then. I just hope it won't be difficult for our purchase dept.

Anyways, Cheers!
