TDA4VP-Q1: Flashing Linux to NOR flash via U-BOOT

Tool/software:

Hi,

I want to flash Linux to the NOR from the U-Boot can you tell me please what the process and which type of file is need?
I succeed to flash u-boot to the nor by these commands:

=> sf probe 0
=> loadb 0x82000000
Send the tiboot3.bin file via Kermit.
=> sf erase 0x0 +$filesize
=> sf update 0x82000000 0x0 $filesize
=> loadb 0x82000000
Send the tispl.bin_unsigned file via Kermit
=> sf erase 0x80000 +$filesize
=> sf update 0x82000000 0x80000 $filesize
=> loadb 0x82000000
Send the u-boot.img_unsigned file via Kermit
=> sf erase 0x280000 +$filesize
=> sf update 0x82000000 0x280000 $filesize

Thanks,
