Linux 燒錄方法 (Linux Flash eMMC Method)

1. 創建一個可以開機的SD Card

先確認SD卡在Ubuntu 系統(x86) 所認到的SD卡代號

Command: sudo fdisk - l

2. 燒錄鏡像到SD 卡中.

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

3. 將flash tool 拷貝到U盤

' 4. '設定終端機(Set Debug Terminal)

Debug 串口調試 (Debug port Setting)

以 Tera Term 为例介绍如何使用串口调试功能

   Baud Rate波特率：115200
   Data 数据位：8
   Parity 奇偶校验：无
   Stop 停止位：1
   Flow Control流控：无

Tera Term Tool

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

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

6. 確認撥碼開關為 SD 卡開機模式

SD 卡開機: 1, 2 on

'eMMC 開機: '2 on

7.打開電源,由終端機可看到開機訊息

8. 開機後請再重新開機一次,系統將會重新劃分磁區大小.

9. 燒錄SD卡前, 請將U盤插入USB port

10. 在系統確認U盤

11. 將flash tool 燒錄鏡像,拷貝到根目錄

12. 解壓縮 flash tool

13. 執行燒錄eMMC

Note: eMMC : /dev/mmcblk2

14. 移除SD卡 ,重新開機,並切換撥碼開關

15. 從eMMC 開機,debug 訊息

RS-232 -- Disable console

Disable debug message output can also improve boot speed

Disable kernel message

setenv mmcargs setenv bootargs ${jh_clk} console=${console} modprobe.blacklist=${modprobe.blacklist} root=${mmcroot} video=HDMI-A-1:${videores} '''quiet'''
env save
reset

Or

Disable debug port

(1) Yocto machine setting:

modify /sources/meta-advantech/meta-fsl-imx/conf/machine$/${MC}.conf

SERIAL_CONSOLES = ";"

(2) Uboot parameter setting:

For the imx8mq, imx8mm, imx8mp:

setenv console disabled
env save
reset
