  • Connect the IPC module to your computer using a USB to TTL cable.
  • Open PuTTY.
  • Configure the serial port information.
  • Restart the IPC module.
  • In the PuTTY window, continuously press the "Enter" key on the keyboard.

Step 3: Enter the following command in the PuTTY window

# Enter commands line by line! Do not copy and paste multiple lines at once!  
setenv ipaddr 192.168.8.200; setenv serverip 192.168.8.250
mw.b 0x21000000 0xff 0x800000
tftpboot 0x21000000 openipc-ssc335-lite-8mb.bin

#如果上面的命令执行不成功，请执行下面的。sf lock 0； 会提示失败， 不过没关系，继续下面的

# if there is no tftpboot but tftp then run this instead
tftp 0x21000000 openipc-ssc335-lite-8mb.bin
sf probe 0; sf lock 0;
sf erase 0x0 0x800000; sf write 0x21000000 0x0 0x800000
