No problem... You can still learn all the stuff. I have done a bit hands on on RPI board with the help of instruction given on > http://elinux.org/Main_Page for porting Linux image for RPI board using SD card.It was simple,follow the steps and you are done. > my Questions are. > i) Where we have used u-boot(i have basic knowledge.) When you have ported on raspi, you have basically just copied the whole linux fs image to the sd card. I won't say that as porting or flashing. ;-) You need to find the default ram address and other first boot addresses. Then try to flash the uboot image. Images can be flashed to sd card or nand flash via serial/usb protocol that actually depends on your board. Once you have flashed the uboot, you will learn the further steps of how to point the kernel image and to save it in sd card or flash. I will recommend you to atleast give a try to Embedded Linux Primer. > ii) Where is the usage of kernel. Woah... Thats a heavy one !! Bro, its the same as that in your computer. Kernel has the same function here too except that it has to compiled with gpio support of your board othrwse no fun here. > > Now if i have to port Debia to another ARM board,what are the steps we must follow.Need Help.I know that first we have to install U-boot onto the board and than we can carry on.I had even tried to go on through U-Boot PDF ftp://ftp1.digi.com/support/documentation/90000852_c.pdf but find no help. Which board are you working on ? There are plenty of boards out there and the basic way to flash may vary. > > > > -- > Mailing list guidelines and other related articles: http://lug-iitd.org/Footer -- Mailing list guidelines and other related articles: http://lug-iitd.org/Footer
