Thread: How to configure the RAM's location in zoom2 board

hi,

know question not directly related forum.. since did not find answer questoin posted on many other forums, posting here hoping 1 surely clarify doubt..(if think can answer in perticular forum pls let me know d link..) thnx in advance..

using zoom2 oamp3430 chipset android development. have doubt related address of ram u-boot need loaded.
using fastboot loading u-boot zoom2's nand. use following command same,

"sudo ./fastboot flash bootloader ./u-boot.bin"
, works absolutely fine. , on booting phone per flow u-boot loaded dram(physical address: 0x80000000) , boots up.

tried loading u-boot .bin ram location directly pc using trace32/jtag, , physical address of dram 0x80000000, used following command in trace32,
"data.load x:\bootloader\u-boot\u-boot.bin 0x80000000", load image dram system did not boot up.
later found system.map file u-boot 0x80e80000 corresponds _start hence used command
"data.load x:\bootloader\u-boot\u-boot.bin 0x80e80000"
, time board booted absolutely fine.
here main doubt when load image nand using fastboot (both x-loader , u-boot), fastboot doesnot ask infomation starting address of image(in case 0x80e80000), how works on booting board, x-loader loads u-boot address 0x80e80000 , starts executing, x-loader fetches information needs load u-boot 0x80e80000 location of dram , start executing.
(the same thing applies x-loader also, _start address system.map x-loader 0x40208800 , how rom code loads x-loader image 0x40208800 address of onchip sram )

hey why u ppl lazy.. jus reply atleast if question need posted somewhere else.. or understanding wrong.. .. jus reply.. total newbe forum.. hope 1 understands probs.. thnx in advance..
