Linux 燒錄方法 (Linux Flash eMMC Method)

1.Prepare a Linux host system Ubuntu x64 v18.04. Download the image file and unzip the image.tar.gz file on Linux host PC.

    $ sudo tar zxvf EPC-R7200_Nano.tar.gz
    $ cd 210/

2.Enter to recovery mode by holding the recover button and plug power to boot. Release recover button around 3 seconds after plug in power.

3.Connect Micro USB cable from EPC-R7200 Micro USB port to Linux host PC USB TypeA port. Check the device is in recovery mode by command “lsusb”. Will get NVidia Corp. with ID 0955:7f21

4.Execute command to flash imag:

  @risc-Default-string:~/EPC_R7200/210$ sudo ./flash.sh nano-epcr7200 mmcblk0p1

Update the flash command for DIV0003:

5.Wait around 10~15 minute to flash image to device:

6.Check the device login to system:

login user: ubuntu/ubuntu

7.Check the eth1 can get the IP Addr:
