Hi Maecenas,

This is our design, have not reviewed by Intel and we currently don't have any resource to develop it. I am simply looking for a JTAG debugger that I can plug into the I210 JTAG port and either through command line or some software that I can use to read the I210 registers.

Hi Maecenas,

Thank you for your response. Do the JTAG tools, from your link above and I am reposting it here for reference: https://designintools.intel.com/product_p/stlgrn34.htm

allow me to read and write (when writeable) to all the PCIe registers found in chapter 9 of the data sheet? (https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/i210-ethernet-controller-datasheet.pdf)

If the JTAG tools allow only read/write (when writable) access to a subset of the PCIe registers then please list which subset or point me to a document that list this subset.

Thank you.
