Hi All,
I have some basic working experience with u-boot but don't have complete understanding.
I have to customize u-boot of a router and i want to know how to start ??
what hardware are necessary like serial, JTAG etc ??
Thanks in advance
You can get a USB TTL adapter for about a dollar from ebay. Like this Amazon.com: Qunqi CP2102 Module STC Download Cable USB 2.0 to TTL 5PIN Serial Converter: Computers & Accessories. Serial pin out info can be found for most models on the openwrt wiki. Look for debricking guides.
Also see pepe2k/u-boot_mod and Breed uboot
i have enabled the serial console.
But my question was for a new board that is not yet suppported !!
How to do changes in uboot ?
How to change the flash layout .. especially size ??
How to install uboot in case i crash uboot ??
Debricking is for supported hardware .. i am talking about new hardware that is not supported .
Thanks in advance.
