JTAG-HS3 SPI support meaning

[ayazar]

Hi,

In the technical documents, it is stated that HS3 does not support SPI programming but HS2 does. I want to clarify the meaning of "SPI support". Does it mean directly programming an SPI Flash with a direct SPI interface without an FPGA or SoC? Most of the case, I program SPI flashes via FPGA or SoC, no direct access to SPI ports. As far as I understand, this scenario is also supported by HS3.But, I just want to make sure before purchase.

Thanks.

Hi @ayazar,

Your understanding is correct; the SPI programming refers to the ability to directly use / "send out" SPI signals to directly interface with SPI devices.

However, if the flash memory is set up in a master serial configuration with the onboard FPGA / SoC (like how Digilent's boards flash memories are set up where they are only accessible through the FPGA), you can still configure the flash memory through the Vivado Hardware Manager via the JTAG HS3 with the .bin file; it just gets routed through the FPGA.

Let me know if you have any questions.

Thanks,
JColvin
