uboot环境变量 以下所有的命令，都在串口工具进行执行

ubifsmount- mount UBIFS volume
ubifsumount- unmount UBIFS volume
ums       - Use the UMS [USB Mass Storage]
usb       - USB sub-system
usbboot   - boot from USB device
version   - print monitor, compiler and linker version
STM32MP> help uboot
Unknown command 'uboot' - try 'help' without arguments for list of all known com
mands

STM32MP> help loadb
loadb - load binary file over serial line (kermit mode)

Usage:
loadb [ off ] [ baud ]
    - load binary file over serial line with offset 'off' and baudrate 'baud'
STM32MP> help go
go - start application at address 'addr'

Usage:
go addr [arg ...]
    - start application at address 'addr'
      passing 'arg' as arguments

Usage:
gpio <input|set|clear|toggle> <pin>
    - input/set/clear/toggle the specified pin
gpio status [-a] [<bank> | <pin>] - show [all/claimed] GPIOs
