- ROCKPro64 was set up
- debian and uboot for testing
- allows for PCIe reinitialization by running ‘pci enum’ in uboot
- Further testing on the SERDES was performed, the RX seemingly doesn’t get what the TX sends
- Whether the signal arrives can be seen by whether the CDR locks, since the phase relationship stays constant between the TX and RX domains when that happens
- At 125 MHz for x2 and 250 MHz for x1 gearing at 2.5 Gbit/s, if PCIe is unconnected it is 90 / 180 MHz, since the refclk runs at a lower frequency
