Alcatel Web Touch One – design information

Short U-Boot course

After booting, system will accept commands from UART that is located on JTAG connector.

Transmission is done in 115kbit/s 8N1 format. Below are some commands that may be interesting:

“setenv stdout serial” – redirects output messages from LCD to UART

“bmp display <address> <x> <y>” – displays bitmap from memory on LCD screen

“loadb <address>” – loads binary file using Kermit protocol into memory (be sure that you redirected messages to UART before),

“go <address>” – runs program from memory (for example loaded before using loadb/loads commands” and many others, please enter “? or help” for more info.

Das U-Boot loader allows loading new applications into system memory, and then running them. Thanks to this any required behavior (for example dancing penguins on screen) can be achieved. In uboot.tgz archive there are two applications included that can be used in early tests “hello_world” and “timer”.
