VOL_UP_N(P0_B2)信号的作用是什么？

我在button mcu源码中看到定义了VOL_UP_N（P0_B2），并且在程序中赋予了其功能，但是原理图中并没有使用该管脚，如下图所示：

BC0AAE05-1E05-482b-A12A-E49B80CCB3281283×644 136 KB

请问是我下载代码不正确吗？请问有button mcu源码功能分析的指导吗？现在我烧写了button mcu和cypd4226的镜像以后，插上CVM，按下按钮不能让CVM上电，我需要分析原因。

However, I can provide information on the Jetson AGX Orin modules and their characteristics, as well as the flashing process.

The Jetson AGX Orin modules are a series of system-on-modules (SoMs) developed by NVIDIA. They are designed for edge AI applications and come in various configurations, including development and production modules.

The development modules are sold as part of a developer kit, while the production modules are compatible with specific carrier boards and are intended for production use.

Here is a comparison of some of the Jetson AGX Orin modules:

  • Jetson AGX Orin Dev-Kit Module (P3701-0000): Development module, 32GB DRAM, flashes QSPI-NOR and eMMC.
  • Jetson AGX Orin 32GB-DRAM (P3701-0004): Production module, 32GB DRAM, flashes QSPI-NOR and eMMC.
  • Jetson AGX Orin 64GB-DRAM (P3701-0005): Production module, 64GB DRAM, flashes QSPI-NOR and eMMC.
  • Jetson AGX Orin Industrial (P3701-0008): Production module, 64GB DRAM, flashes QSPI-NOR and eMMC.

The flashing process for these modules involves using the flash.sh script or l4t_initrd_flash.sh for some modules. The configuration file used for flashing depends on the specific module and carrier board being used.

In summary, the provided text does not contain any information related to the Jetson AGX Orin button mcuVOLUPNP0B2 BC0AAE051E05482bA12AE49B80CCB328 1283644 136 KB button mcubutton mcucypd4226CVMCVM.

我是完全参照jetson orin A05官方原理图设计了我们自己的载板，目前已经烧写了CYPD4226和BUTTON MCU EFM8的镜像，调试发现按下电源按钮以后，VDD_5V和VCC_SRC电源能够短暂上电，说明BUTTON MCU识别到了按钮按下，即P0.0管脚检测到了BUTTON_POWER_ON_N信号输入，并且P1.3管脚输出VIN_PWR_ON信号为高电平，但是P1.5 EFM8_MODULE_POWER_ON信号没有输出高电平，想知道原因是什么

Hi gaga,

What’s the Jetpack version in use?

Do you have any custom requirement to update the button MCU firmware?
This MCU is from SiliconLab and they may better know the firmware and the logic inside.

JETPACK版本是6.02，button mcu的源码从Jetson Download Center | NVIDIA Developer

下载

We don’t have this release.

Please share the result of the following command on your board.

$ cat /etc/nv_tegra_release
$ dpkg -l | grep nvidia-jetpack

How did you perform this task?
Could you share the steps for this?

问题已经解决了，原因是我没有去掉一个冗余电阻，导致EFM8_FORCE_SHUTDOWN信号检测不正确，去掉电阻以后，JETSON ORIN CVM可以正常上电了，谢谢
