麻煩提供基本資訊先
-
NV devkit or custom board
-
Jetpack版本

如果不是nv devkit,有沒有辦法在devkit上複製問題
1.我们自己做的板子，用的nvidia模组
2.Jetson_Linux_R35.2.1_aarch64
我们把USB：USB2_DN USB2_DP 这个USB连接到了MINIPCIE接口上。当我把minipcie接口的外设插上之后，就会出现该问题。
外设是“ TDTECH MT571X”

請問有沒有辦法用類似的裝置在nv devkit上複製
你的意思是在英韦达的开发板上复现该问题吗？
是的 基本上所有問題我們都希望能在devkit開發版上先複製出來我們才比較容易後續確認
不是每個issue都看幾行log就能知道問題在哪的
英韦达板子没有MINIPCIE接口。暂时不能在英韦达开发板上复现该问题。
arm-smmu 8000000.iommu这个是DMA用的，会和我的硬件设计有关吗 ？
还请您在帮忙看看该问题。 谢了！
