HPS IO48 OOBE MICTOR JTAG resistor

In regards to the documentation (https://www.intel.com/content/www/us/en/programmable/documentation/sbe1494623766556.html#vsg14976512...) for the JTAG section of the HPS IO48 OOBE daughtercard, it mentions that there are resistor mods available to perform an either/or connection between the FPGA_JTAG and the HPS_JTAG. The documentation has these resistors labeled as "Ra" and "Rb", however, nothing on the board is labeled "Ra" or "Rb." I also cannot locate a schematic for this daughtercard. Can someone provide the schematic or explain exactly which resistors are considered "Ra" and "Rb"?

 

And also, for the Stratix 10 SoC development kit, would "FPGA_JTAG" be considered the USB-to-Byte-Blaster connection (J57)? I'm trying to figure out if I can access the HPS JTAG using J57, or if I need to get a separate JTAG programmer.

Hi,

 

I apologize for the late in response, I manage to find the schematic for the HPS IO48 OOBE daughtercard(Second page):
