It describes how to port the NVIDIA® Tegra® Linux Driver Package and the U-Boot bootloader from NVIDIA® Jetson™ TX2 Developer Kit to other hardware platforms.The examples described include code for the Jetson TX2 Developer Kit (P2771). BOARD NAMINGTo support your board in L4T, you must select a simple lower-case, alpha-numeric name for your board. The name can include dashes (-) or underscores (_) but cannot contain spaces. For example:jetson-tx2p2771-000-500myboardThe name you select appears in:• Filenames and pathnames•U-Boot and Linux kernel source code•User-visible device tree filenamesAdditionally, this name is exposed to the user through the U-Boot command prompt and various Linux kernel proc files.In this document, <board> represents your board name.NVIDIA CONFIDENTIALYou must also select a similarly-constructed vendor name. The same character set rules apply, such as the following example:nvidiaIn this document, <vendor> represents your vendor name.Do not re-use and modify the existing NVIDIA® Jetson™ TX2 DeveloperKit code without selecting and using your own board name. If you donot use your own board name it will not be obvious to Jetson TX2users whether the modified source code supports the original JetsonTX2 Developer Kit board or your board. PLACEHOLDERS IN THE PORTING INSTRUCTIONS Placeholders are used throughout this document, substitute an appropriate value for each placeholder when you enter the commands.•<function> is a functional module name, which may be power-tree, pinmux, sdmmc-drv, keys, comm (Wifi/BT), camera, etc.•<board> is a name you have selected to represent your platform. For example, p2771 is the name of the Jetson TX2 Developer Kit. NVIDIA <board> names use lower case letters.•<version> is a board version number, such as a00. Files for NVIDIA reference boards include a version number. Files for customer platforms are not required to include a version number.•<vendor> is the name of your organization, or the name of the vendor for your board.•<root> is the device that holds root file system for the platform. At present, the supported value is emmc.PINMUX CHANGESIf your board schematic differs from that for Jetson™ TX2 Developer Kit board, you must change the pinmux configuration applied by the software.The Jetson_TX2_customer_pinmux_release.xlsm spreadsheet is provided to:•Show the locations and default pinmux settings•Define the pinmux settings in the source code or device treeThe spreadsheet is available at:https:///embedded/downloadsYou must customize the spreadsheet for the configuration of your board.For information on customizing the configuration files, refer to the Tegra Linux Driver Package Development Guide“MB1 Platform Configuration” and “Configuring Pinmux, GPIO and PAD” topics.PORTING U-BOOTPerform the following actions in the U-Boot source code to add support for your board.1.Copy include/configs/p2771-0000.h to include/configs/<board>.h.2.Edit the set of enabled devices and features in <board>.h as appropriate for yourboard. For example, you must change the following:#define CONFIG_TEGRA_BOARD_STRING "NVIDIA p2771-0000"3.Copy arch/arm/dts/tegra186-p2771-0000-500.dts toarch/arm/dts/tegra186-<board>.dts.4.Edit the set of enabled devices and their parameters (e.g. GPIO and IRQ IDs) integra186-<board>.dts as appropriate for your board.You may need to add, remove, or edit nodes and properties.U-Boot and the Linux kernel do not always use the exact samedevice tree schema (bindings) to represent the same data. Followexamples from U-Boot rather than from the Linux kernel.5.Add tegra186-<board>.dtb to arch/arm/dts/Makefile.6.Copy configs/p2771-0000-500_defconfig toconfigs/<board>_defconfig.7.Edit <board>_defconfig to refer to your board name.8.Edit arch/arm/mach-tegra/tegra186/Kconfig to add target config andKconfig.9.Copy the board/nvidia/p2771-0000/ directory toboard/<vendor>/<board>/.10.Edit all the files in board/<vendor>/<board>/ to refer to your board name ratherthan the p2771-0000. The files in this directory contain many instances of thep2771-0000 board name.11.Edit board/<vendor>/<board>/MAINTAINERS to provide the correct maintainercontact information for your board.12.Edit board/<vendor>/<board>/<board>.c to provide the correct PMICprogramming for your board, if required.PORTING THE LINUX KERNELIt is assumed that you are using the CVM module provided by NVIDIA and that it has not been modified; the eMMC, PMIC, and DDR are the same with the same routing of lines. The modifications you are making are for the CVB baseboard that hosts all the peripherals. Consequently, based on the peripherals present on your baseboard, you can modify the .dts files by disabling/enabling the controllers and changing the supplies.To port the kernel configuration code (the device tree) to your platform, modify one of the distributed configuration files to describe the design of your platform.The configuration files available at:<top>/hardware/nvidia/platform/t18x/<top>/hardware_nvidia/soc/t18xThe final DTB file used is:tegra186-quill-p3310-1000-a00-00-base.dtsBy reading the above file, you see which other .dtsi files are referenced by include statements. Common .dtsi files that may be modified to reflect hardware design changes include:Verify that no other .dts or .dtsi file, including these .dts files, overrides any changes you make.As a best practice, create your own set of .dts files based on the Quill files already present. Rename your newly created files to the name of your board.Note:Use fdtdump or dtc to generate a .dts from the final .dtb file andcheck if your changes have taken effect.The command usage is as follows:dtc -I dtb -O dts tegra186-quill-p3310-1000-a00-00-base.dtb > tegra186-quill-p3310-1000-a00-00-base.dtsfdtdump dts tegra186-quill-p3310-1000-a00-00-base.dtb > tegra186-quill-p3310-1000-a00-00-base.dtsPower Tree ChangesThe Jetson P2597 baseboard has a GPIO expander. Some of the pins on the GPIOexpander are used as a GPIO regulator. One such usage is to enable vbus-2-supplywhich is powered using vdd_usb2_5v GPIO regulator. If your custom board does nothave the vdd_usb2_5v supply, the xhci driver enumeration fails on the target system.To solve this situation, you must:1.Change the supply with battery_reg using the .dtsi file located at:hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-power-tree-p3310-1000-a00-00.dtsi2.Regenerate the DTB.3.Flash with the correct DTB.The modifications are as follows:pinctrl@3520000 {vbus-0-supply = <&vdd_usb0_5v>; vbus-1-supply = <&vdd_usb1_5v>;vbus-2-supply = <&battery_reg>;vbus-3-supply = <&battery_reg>;vddio-hsic-supply = <&battery_reg>;avdd_usb-supply = <&spmic_sd3>;vclamp_usb-supply = <&spmic_sd2>;avdd_pll_erefeut-supply = <&spmic_sd2>;};Another ExampleIf you wish to:•Disable xhci which is a USB 3.0/USB 2.0 controller, disable the following node.•Change the lane configuration, update the following node.xhci@3530000 {status = "disabled";phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>,<&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(1)>,<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(1)>;phy-names = "utmi-0", "utmi-1", "usb3-1";};For the detailed information about .dts files, refer to the documentation at Documentation/devicetree/bindings in the NVIDIA released Linux kernel source package.USB LANE MAPPINGUSB 3.0 has 4 super-speed ports. Not all can be used in the same implementation because of lane sharing between PCIE, SATA, and XUSB. Possible combinations for USB 3.0 are as follows.The customer pinmux spreadsheet contains all Jetson TX2 pin names and ball names to represent which ball names are used for the super-speed connector, and the pinmux configuration of those pins.An example configuration is available in the Jetson TX2 OEM Product Design Guide. Each external super-speed connector has both USB 2.0 (DP, DN) and USB 3.0 lines (TX+-, RX+) linked to the connector. A possible exception is where a fixed on-board device is connected to super-speed lines and does not require USB 2.0 compatibility. Required Device Tree ChangesThe following device tree properties must change when USB configuration changes, for example, for one USB 2.0 and one USB 3.0 port used in the xhci controller.Under the XHCI node:•List all UPHY lanes required, for example:phys = <PADCTL_UTMI(0)>, // for USB2.0 port0<PADCTL_USB3(0)>, // for USB3.0 port0•Provide a naming convention to retrieve the above UPHYs from the kernel: phy-names = “utmi-0”, “usb3-0”;Under pinctrl to pinmux node:•Create a node for each UPHY lane, for example:●For usb2.0, usb2-port0 { // node name could be anything•n vidia,lanes = “otg-0”;// Required properties.•n vidia,function = “xusb”;// Optional properties, as per padctrldocumentation, function property is required for USB2.0 port and in this case,it is “xusb”•nvidia,port-cap = “PORT_HOST_ONLY”; // Optional properties and could be “PORT_OTG”●For USB3.0, usb3-port0 {•n vidia,lanes = “usb3-0”; // required property•nvidia,port-cap = “PORT_OTG_CAP”; // required property for lane usb3-0. The above allocations will work when UPHY lanes are owned by each client(xhci/xudc/pcie..).As per the above example:•XHCI must be owned by LAN0 for usb3-0.•Lane allocation can be performed by either ODMDATA or allotted to UPHY to each client in the bpmp-dtb file.•ODM Data: Bit 24 to 28 are used to allocate lanes with Lane3, by default, is allocated to PCIE.•ODMDATA=0x1090000; While flashing for Jetson TX2.Lane allocations are as follows:For the detailed information about UPHY lanes, refer to the documentation at:kernel/t18x/Documentation/devicetree/bindings/pinctrl/nvidia,tegra186-padctl.txtFLASHING THE BUILD IMAGEWhen flashing the build image, use your specific board name. The flashing script uses the configuration present in the <board>.conf file during the flashing process.To flash the build image•Execute the following command.$ sudo ./flash.sh <board> mmcblk0p1HARDWARE BRING-UP CHECKLISTThis section provides a checklist for the platform hardware bring-up process.

Jetson TX1 和 TX2 电压和电流监控配置应用指南说明书
DA_08564_001 | July 20, 2017 Release 28.1DOCUMENT CHANGE HISTORYNVIDIA® Tegra® Board Support Package for the Jetson TX1 and TX2 module works together with platform hardware to implement a system Electrical Design Point (EDP) management strategy to maximize CPU and GPU performance within system EDP constraints for the platform.Voltage comparator and a current monitor detect under-voltage and over-current scenarios are outlined. When the sensor outputs are asserted, Tegra hardware quickly throttles CPU and GPU clocks as configured by software to reduce the current load. The Jetson module includes on-board power monitor, INA3221, to monitor the voltage and current of the following power rails:④VDD_IN④VDD_GPU④VDD_GPUThe alert outputs of INA3221 include:④ALERT④CRIT④WARNThey are fed into a SOC_THERM input on Tegra. When one or more of those alert outputs are asserted, SOC_THERM hardware reacts to reduce Tegra power consumption and avoid violating the current limits.Configuring the Voltage and Current MonitorThe power monitor accepts the configuration data from the powermon Device Tree source file.The powermon dtsi file for Jetson TX1 is available at:kernel/arch/arm64/boot/dts/tegra210-platforms/tegra210-jetson-cv-powermon-p2180-1000-a00.dtsiThe powermon dtsi file for Jetson TX2 is available at:hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-p3310-1000-a00-powermon.dtsiThe following code snippet is TX1 powermon dtsi file:i2c@7000c400 {ina3221x: ina3221x@40 {compatible = "ti,ina3221x";reg = <0x40>;ti,trigger-config = <0x7003>;ti,continuous-config = <0x7607>;ti,enable-forced-continuous;#io-channel-cells = <1>;#address-cells = <1>;#size-cells = <0>;status = "disabled";channel@0 {reg = <0x0>;ti,rail-name = "VDD_IN";ti,shunt-resistor-mohm = <20>;ti,current-critical-limit-ma = <2105>;shunt-volt-offset-uv = <&p2180_shuntv_offset>;};channel@1 {reg = <0x1>;ti,rail-name = "VDD_GPU";ti,shunt-resistor-mohm = <10>;shunt-volt-offset-uv = <&p2180_shuntv_offset>;};channel@2 {reg = <0x2>;ti,rail-name = "VDD_CPU";ti,shunt-resistor-mohm = <10>;shunt-volt-offset-uv = <&p2180_shuntv_offset>;};};Where:④The current-critical-limit-ma of channel 0 VDD_IN is calculated from thesystem EDP limit and the Jetson module input voltage.The critical current limit = System EDP limit / VDD_IN voltage④The system EDP limit for the Jetson TX1 module, as part of the Jetson TX1 DeveloperKit, is defined at:kernel/arch/arm64/boot/dts/tegra210-jetson-cv-base-p2597-2180-a00.dtsThe code is as follows:sysedp {compatible = "nvidia,tegra124-sysedp";nvidia,margin = <0>;nvidia,min_budget = <0>;nvidia,initial_budget = <40000>;};④Where the critical current limit for 19V VDD_IN is calculated as follows:19V VDD_IN = 40,000 / 19 => 2105mAThe system integrator must configure the correct critical current limit based on the module input voltage. For example, the critical current limit for 8V VDD_IN iscalculated as follows:Critical current limit for 8V VDD_IN = 40,000 / 8 => 5000mABy default, the Jetson TX1 Developer Kit voltage and current monitor is configured for 19V input. If less than 19V input is used, the user must reconfigure the critical current limit of VDD_IN. If not set, unexpected CPU/GPU throttling and performance slowdown may occur.By default, the Jetson TX2 Developer kit critical current limit of VDD_IN is set to the maximum possible value of 8190mA. Therefore, it is not necessary to modify the critical current for lower input voltage unless user wants to configure the critical current limit for a specific input voltage.NoticeALL NVIDIA DESIGN SPECIFICATIONS, REFERENCE BOARDS, FILES, DRAWINGS, DIAGNOSTICS, LISTS, AND OTHER DOCUMENTS (TOGETHER AND SEPARATELY, "MATERIALS") ARE BEING PROVIDED "AS IS."
