Flash images

This section introduces the production steps of flash images of USB disk, SD card and master chip.

Flash an empty chip

Get Flash Tool

git clone https://gitee.com/qiming-zhixian/ssd20x-tools.git

Open Flash Tool, connect chip ttyS0 with ISP Debug, click Connect, and select flash type.

copy images to local

cp ${SDK_PATH}/ssd20x-images-open/WT2012 /mnt/hgfs/shared/

Flash successfully, then power on again.

Flash system

Open tftpd32.exe, set the server path, and set the computer LAN to be in the same network segment as the IP of the development board (the PC firewall needs to be turned off).

Connect the board to the network, power on the board, press and hold Enter, then enter the uboot terminal and set a static IP.

setenv gatewayip 192.168.1.1
setenv ipaddr 192.168.1.127       //set device ip
setenv netmask 255.255.255.0
setenv serverip 192.168.1.100     //set server ip
saveenv

Enable the network port on computer and execute the flash command.
```
estart
estar
```

Flash form USB disk

USB disk blank upgrade is not supported. The user needs to manually enable the USB disk upgrade, and execute the following command to complete the upgrade
```
setenv UpgradePort 1
saveenv
usbstar
```

Flash from SD card

The SD card upgrade function is enabled by default and it supports blank chip upgrade. After the chip is powered on, if there are IPL, IPL_CUST and UBOOT in the SD card, these programs will be loaded and run, and the upgrade can be completed by executing the following commands.
