The USB flash drive cannot be detected in Recovery Boot bash-5.1 on JP6.0

亲爱的英伟达团队，您好：
我当前使用的是Jetson Agx Orin开发套件。

在JP5.1.3上可以通过 在启动过程中按esc进入UEFI界面：
选择Device Manager → NVIDIA Configuration → L4T Configuration → OS chain A status：选择Unbootable

进入Recovery Boot 的 bash-5.0 ，可以操作U盘，如果U盘里有rootfs，可以用来更新app分区。

但在JP6.0中，用上面的方法进入bash-5.1 后，不能发现U盘设备。
在JP6.0的释放日志中没有发现相关说明
Jetson-Linux r36.3 GA Release Notes (nvidia.com)

下面是日志文件

请问JP6.0的Recovery Boot bash中还不支持U盘设备吗

Hi,

這個問題應該是源自JP6之後usb driver被從kernel image改到kernel modules.

initrd 裡面有這些ko files應該要手動probe之後才有辦法找到usb device.

/lib/modules/5.15.136-tegra$

./kernel/drivers/usb/gadget/udc/tegra-xudc.ko
./kernel/drivers/usb/typec/typec.ko
./kernel/drivers/usb/typec/ucsi/typec_ucsi.ko
./kernel/drivers/usb/typec/ucsi/ucsi_ccg.ko

下面输入的命令有问题吗，执行报错

bash-5.1# cd /lib/modules/5.15.136-tegra/
bash-5.1# modprobe -a ./kernel/drivers/usb/gadget/udc/tegra-xudc.ko
modprobe: WARNING: Module ./kernel/drivers/usb/gadget/udc/tegra-xudc.ko not found in directory /lib/modules/5.15.136-tegra

請問這個是rel-36.3 還是36.2?

这是36.3
日志里也有写

Jetson System firmware version 36.3.0-gcid-36191598 date 2024-05-06T16:58:59+00:

Hi，Wayne ，我搜索日志发现以下信息

是不是表明USB驱动已经加载过了？

你可以先嘗試用initrd flash 燒錄到USB drive然後看做這步驟的時候initrd flash load哪些driver…

Hi,Wayne
我执行下面命令

sudo ./tools/kernel_flash/l4t_initrd_flash.sh -c tools/kernel_flash/flash_l4t_t234_nvme.xml --external-device sda1  jetson-agx-orin-devkit external

当串口输出停在bash时，调用lsblk，可以找到U盘设备 sda1

bash-5.1# lsblk

这次的日志和之前比较多加载了几个ko文件，
MobaXterm_COM7USBCOM7_20240912_104215.txt (79.2 KB)

insmod /lib/modules/5.15.136-tegra/updates/drivers/spi/spi-tegra210-quad.ko

但我手动加载时遇到问题：
1，insmod 无法执行，没这个命令
2，modprobe 加载ko还是报上面not found in directory的错误

请问，还有什么可以尝试的吗

Sorry for the late response.
