recovery

How to recover bootloader

The SPL and U-Boot are stored inside the SPI flash on board. There may be situations where you accidentally emptied the flash or if the flash is damaged on your board. In these situations, it's better to recover the bootloader.

Before you recover the bootloader, please double check the boot mode jumpers(Switch_2) on your board has already been switched to UART mode(GPIO_1,GPIO_0: 1,1);

  1. Configure the serial port settings: 115200bps;

  2. Power up, you will see an output like this:

    CCCCCCCCCCCCCCCCCCCCC
    
  3. Please transfer the recovery binary jh7110-recovery-20221205.bin by xmode and you will see recovery menu automaticlly;
