  1. 根据需求对节点执行power cycle ipmitool power cycle

  2. 设置topo python3 ocsdiag.py -i 10.57.216.95,10.57.216.96,10.57.216.97,10.57.216.98 -e 2,4,6,8 -c topo-config -p 32

  3. ocs link reset ocs_link_reset -i 10.57.216.95,10.57.216.96,10.57.216.97,10.57.216.98 -e 2,4,6,8

  4. 设置high freq(根据PCB走线) python3 ocsdiag.py -i 10.57.216.97 -e 8 -c highfreq-tune

  5. 设置low freq python3 ocsdiag.py -i 10.57.216.98 -e 8 -c rtmr-prbs python3 ocsdiag.py -i 10.57.216.97 -e 8 -c lowfreq-auto-tune

    python3 ocsdiag.py -i 10.57.216.97 -e 8 -s all -c reg-wt -p lowfreq_eq -v 128

  6. 设置tia_peak(根据PCB走线) python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c tia-peak-tune

  7. 校准ibias (onoc) python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c ibias-auto-tune

  8. 校准ibias (onet) python3 ocsdiag.py -i 10.57.216.98 -e 4 -s all -c ibias-auto-tune -p 10.57.216.96 python3 ocsdiag.py -i 10.57.216.96 -e 4 -s all -c ibias-auto-tune -p 10.57.216.98

  9. 校准mgc onoc python3 ocsdiag.py -i 10.57.216.98 -e 8 -c rtmr-prbs python3 ocsdiag.py -i 10.57.216.98 -e 8 -s all -c mgc-auto-tune

8.1 校准mgc onet tx端: python3 ocsdiag.py -i 10.57.216.98,10.57.216.96 -e 4 -c rtmr-prbs rx端: python3 ocsdiag.py -i 10.57.216.96 -e 4 -s all -c mgc-auto-tune python3 ocsdiag.py -i 10.57.216.98 -e 4 -s all -c mgc-auto-tune

  1. 查看retimer 误码情况 python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr all"

  2. 查看眼图情况 python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 1 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 2 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 3 eye 1 a" python3 ocsdiag.py -i 10.57.216.97 -e 8 -c vcmd -p "rtmr 4 eye 1 a"

    如果眼偏下,则op_current需要调小。

  3. 保存配置

先用vgc = 255,校准,然后手动改为200,发现recovery没增加了。
