My LH7A404-11 Card engine schematic shows CD_GND of U13[14] going to J1B[80]. On the SDK, J1B[80] is the RTCK, going to the JTAG J36[11]. The lines on both boards do match the schematics.

1. Is sharing the JTAG RTCK line with the CD_GND intended?
2. I don't see the JTAG RTCK line going anywhere else on the SDK brd other than from J1B[80] to J36[11], so am unclear of your implementation. I'm sure U13 could care less about the JTAG line, so can I assume the LH7A404 doesn't need to the RTCK line? Could you please clarify?
