Hello everyone,
Now, I try to follow the Android_Quick_Start_Guide document. In topic 3.4 Booting, I don't understand about U-boot >. What is a U-boot > ? Where can I put the command such as
U-Boot > setenv bootcmd booti mmc2
U-Boot > setenv bootargs console=ttymxc3,115200 init=/init video=mxcfb0:dev=ldb,bpp=32
video=mxcfb1:off video=mxcfb2:off fbmem=10M vmalloc=400M androidboot.console=ttymxc3
androidboot.hardware=freescale
U-Boot > saveenv
Thank you.

Hi,
u-boot is universal Bootloader code.
u-boot> is a u-boot prompt and used to pass configuration specific parameter.
You can configure display device, memory. console port and so on.
Thanks

"After downloading the images, you can boot the board by connecting
it to the power supply". U-boot is Android / Linux bootloader, so You should
see "U-boot>" prompt on terminal, connected via debug UART.
On the SDP board debug UART is implemented via UART-USB converter,
so, please install FDTI driver for it and use Teraterm program.
Have a great day,
Yuri

Hello Patchara,
May below link helpful to you...
Presentation < U-Bootdoc < DENX
U-boot is the primary boot loader, by the use of it we set/change/configuration of the board related things (i.e. display device, Ethernet things, console related, kernel image, RFS, memory related, boards I/O related etc.) as Saurabh said .. :smileyhappy:
Please go through the above link.
U can set any command by use of
'setenv command'
and save it by use
'saveenv'
command in u-boot called as its arguments/parameters.
may these information helps you.
