Linux 燒錄方法 (Linux Flash eMMC Method)

1. 創建一個可以開機的SD Card (Create a bootable SD card )

先確認SD卡在Ubuntu 系統(x86) 所認到的SD卡代號 ( Check the SD card symbol in Ubuntu System (x86)

Command: sudo fdisk - l

![圖片連結](./img_EPC-R3720/RSB-3720_SD_fdisk_info_2021-10-28_113030.jpg "RTENOTITLE".md)

2. 燒錄鏡像到SD 卡中. (Flash Image into SD card)

Command : sudo dd if=3720A1AIM30LIVA0333_iMX8MP_6G_2021-10-05.img of=/dev/sdf bs=1M conv=fsync

![圖片連結](./img_EPC-R3720/RSB-3720_dd_SD_info_2021-10-28_113804.jpg "RTENOTITLE".md)

3. 將flash tool 拷貝到U盤 (Cpye the eMMC flash tool into USB Disk )

![圖片連結](./img_EPC-R3720/RSB-3720_cp_file_into_USB_2021-10-28_115157.jpg "RTENOTITLE".md)

4. 設定終端機(Set Debug Terminal)

Debug 串口調試 (Debug port Setting)

以 Tera Term 為例介绍如何使用串口調試功能 ( Tera Term is kind of terminal tool , we need to set the parameter (Baud Rate , Data, Parity, Stop, Flow Control ) into "Tera Term terminal tool " )

   波特率(Baud Rate)：115200
   數據位(Data)：8
   奇偶校驗(Parity)：无 (none)
   停止位(Stop)：1
   流控(Flow Control)：无 (none) 

Tera Term Tool

Check the Sriel port in Device Manager (查看PC端的串口號)：

if you can not identify the Serial device , please check your serial driver.

5. 將可開機的SD 卡插入 SD 插槽, 並打開電源開機 (Plug into the SD card into SD Card Slot , then turn on the power)

![圖片連結](./img_EPC-R3720/RSB-3720_SD_solt_2021-10-28_115806.jpg "RTENOTITLE".md)

6. 確認撥碼開關為 SD 卡開機模式 (Check the Switch)

SD 卡開機: 1, 2 on (Set the SD card boot up mode , 1 on 2 on )

![圖片連結](./img_EPC-R3720/RSB-3720_SD_Card_boot_up_2021-10-28_132021.jpg "RTENOTITLE".md)

'*eMMC 開機: '*2 on ( Set the eMMC boot up mode , 2 on , others off)

![圖片連結](./img_EPC-R3720/RSB-3720_eMMC_boot_up_2021-10-28_132058.jpg "RTENOTITLE".md)

![圖片連結](./img_EPC-R3720/RSB-3720_debug_message_2021-10-28_132358.jpg "RTENOTITLE".md)

8. 開機後請再重新開機一次,系統將會重新劃分磁區大小. (If you can not not copy the eMMC flash tool into root file system , please reboot the device , because , the system will the reconfigure the partition )

9. 燒錄eMMC前, 請將U盤插入USB port(Please pulg the USB Disk into USB port before flash eMMC)

10. 在系統確認U盤(Check the USB disk in the Yocto System (Device side) )

![圖片連結](./img_EPC-R3720/RSB-3720_check_usb_in_system_2021-10-28_132956.jpg "RTENOTITLE".md)

<code>sudo apparmor_parser -R /etc/apparmor.d/unprivileged_userns</code>

Security Hardening in Newer Ubuntu

Newer versions of Ubuntu, starting with releases around 23.10/24.04, prioritize security by default. They often ship with an active AppArmor profile specifically designed to restrict the use of unprivileged user namespaces.

Policy Name: /etc/apparmor.d/unprivileged_userns

Purpose: The policy aims to mitigate potential security vulnerabilities by limiting which applications can create these powerful sandboxes.

The Need to Unload

By running sudo apparmor_parser -R /etc/apparmor.d/unprivileged_userns, you are temporarily telling the Ubuntu 24.04 host kernel to:

Ignore (Remove) the policy.

Allow unrestricted use of unprivileged user namespaces by all processes, including the Docker daemon or the user running Docker.

This command is a workaround to loosen a modern security default (Ubuntu 24.04's strict AppArmor policy) to ensure backward compatibility and functionality with certain container and build setups.
