Hi! I'm Valentino and I'm new in the Linux ambient.
I've a sample AT91SAM9261 board of ATMEL and I want to load a DEMO Kernel Image in SDRAM from USB key.

When I connect power supply, on Hyperterminal I can read:

[b]U-Boot 1.1.4 (Sep 14 2006 - 21:04:26)

After to have written the commandos of "Access a USB key", I load the Image file with this command:

U-Boot> fatload usb 0:1 20000000 image-at91sam9261-100 2106016

and on Hyperterminal I read:

[b]reading image-at91sam9261-100
Invalid FAT entry

4096 bytes read
U-Boot>[/b]

and so I don't succeed to continue :cry:

Help me help me!!! :cry:

Hi Valentino,
maybe you forgot to call
U-Boot> usb start
before
U-Boot> fatload usb 0:1 20000000 image-at91sam9261-100 2106016

ciao

Ciao, mi sembra di aver capito che sei italiano, grazie per la tua risposta però i comandi dell'Access USB Key l'ho scritti tutti:
-usb start
-usb storage
-usb dev 0
-fatls usb 0:1
e sono andati tutti a buon fine, infatti mi visualizza la lista dei file della USB key, ma comunque il comando fatload successivamente continua a nn funzionare, mi continua a dare lo stesso errore.

Ora la situazione si è complicata perchè ho provato a scaricare di nuovo l'U-Boot nella data flash tramite SAM-BA 2.6, dopo che ho caricato prima il dataflash.bin e poi l'U-Boot.bin, tutti e due a buon fine, quando lancio il Boot e quindi parte il load del Boot dalla Dataflah all'SDRAM, mi scrive:

RomBOOT
>
Load UBOOT from dataflash[c0008000] to SDRAM[23f00000]
Read Dataflash failed


Ora non so più che fare perchè sono bloccato.
Spero tu possa aiutarmi

Hi,thank you for you answer but the "Access Usb Key" commandos,I have written all:
-usb start
-usb storage
-usb dev 0
-fatls usb 0:1

and them have had success, on hyperterminal I can read the list of USB Key files,but the "fatload" command does not work, I read the same error

Now my situation is gotten worse because I have reloaded the DataFlashBoot-at91sam9261-100.bin and u-boot-1.1.3-at91sam9261ek-100.bin in the Dataflash with SAM-BA 2.6, but when I reset the board, on the Hyperterminal read:

RomBOOT
>
Load UBOOT from dataflash[c0008000] to SDRAM[23f00000]
Read Dataflash failed


help me help me
