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)  [Use Ubuntu 18.04 to create SD card (Test the SD image can boot into Linux without problem that created on Ubuntu18.04 or 20.04)]

RTENOTITLE

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

RTENOTITLE

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

 $ cd ti-sdk-XXX/bin

 RTENOTITLE

$ sudo ./create-sdcard.sh

RTENOTITLE

Select SD card:

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)

 RTENOTITLE

Step3: 確認開機選擇指撥開關(Check the SW1 switch)

            SPL開機模式(SPL boot mode: boot from SD, MMC...) 

            1--off  2---off

            eMMC開機模式(eMMC boot mode):

            1--on  2--off

            Note: After change switch setting. Unplug and plug AC power for the change to take effect.

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