We updated tegra Tx2 with latest Jetpack version and its booting fine.
We need to disable iommu for Pcie controller as our driver has this requirement
To do this we followed
Extracted dts file ( extracted_proc.tx) on the running tegra using dtc tool
Modified it by deleting
iommus = <0x11 0x11>;
after this generated dtb file(tegra186-quill-p3310-1000-c03-00-base.dtb) using dtc tool
copied this to linux_for_tegra/kernel/dtb
After that followed the flash steps to reflash it . Flashing successful . But not booting .
- Could you please check if the above steps are correct?
- Can we disable IOMMU for pcie in jetpack 4.1 ?
- Are the dts file changes correct?
