[x] Wire main I2C bus (master of U13 TCA9548A) to FPGA user I/O.
[x] Move thermometer and power supply I2C to a separate bus, not direclty accessible to FPGA.
[x] Wire GPIO0 of XR77129 to FPGA user I/O.
[x] Reduce number of non-WR crystals, maybe to zero; The USB crystal may be OK to keep, if it stops vibrating when the USB is unplugged.
[x] Reference designators should follow IEEE Std 315-1975, in particular: Q - transistors U - integrated circuits Y - crystals
[x] Missing self-JTAG. Please wire four user I/O pins to the JTAG lines.
