Linux 燒錄方法 (Linux Flash eMMC Method)

使用Flash tool 燒錄鏡像到eMMC (Flash image into eMMC by Flash Tools)

解壓縮檔案(Unzip the files)

mkdir ti-sdk-XXX(XXX represents numbers, e.g. ti-sdk-001)

Command : phill@riscserver-Default-string:/home/RISC_BSP_Home/EPC-R3220/R3220A1AIM20LIV20012_am335x_2021-07-29$ mkdir ti-sdk-001

Unzip file to ti-sdk-001

Command : tar -xJf processor-sdk-linux-image-am335xepcr3220a1-20210729031957.tar.xz -C ti-sdk-001

Step0: 檢查SD卡在Linux 環境的代號 (check SD card symbol in Linux system)

Step1: 創造一張可開機的SD 卡 (Create a bootable SD card)

$ cd ti-sdk-XXX/bin

$ sudo ./create-sdcard.sh

Select SD card:

Select number of partitions:

Select Pre-built System image:

Select tisdk-rootfs-image-XXX.tar.xz(XXX represents machine name, e.g. am335xepcr3220a1):

If you need to transfer whole system to on-board flash, please press y followed by Enter.

Step2: 將可開機的SD 卡插入底板SD卡卡槽(Plug the SD card into Carrier board 's SD card slot)

Step3: 確認開機選擇指撥開關

SD 卡開機模式:

1--off 2---off

Step3:打開電源和終端機 (Turn on the Power & Terminal)

Step4: 利用mk-eMMC-boot.sh 安裝eMMC 鏡像(Flash image to eMMC Flash by mk-eMMC-boot.sh )

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
