Hi Dear Sir
我們這邊客戶的載板搭配NV Jetson module
跑Display Port 1.2結果出現多項Fail
測試Summary和測試軟體設定如下圖1;2
其中我們跑Eye Test時HBR2為PASS,
但跑RBR與HBR 眼圖mask會整個黑掉如圖3
想問這方面有什麼建議?
軟體版本或硬體哪部分可以做改善
再麻煩提供
謝謝

First of all, the custom carrier board design should follow the routing guideline in OEM DG well, such as impedance matching, line to line space, line maximum length and etc… Only that can guarantee the signal quality. Regarding the tuning method, please refer to tuning guide in DLC (http://developer.nvidia.com/embedded/dlc/tx2-series-interface-tuning-compliance-testing-guide) to configure some related registers.
