[U-Boot] Swiching u-boot image in SPI-NOR

[JYOTI DUBEY]

Hello
      I am trying to bring in u-boot.imx (uboot image of u-boot 2013) onto
SPI-NOR of nitrogen 6x board.I used following commands:
>> sf probe 1
>>sf erase 0 0x40000
>> fatload mmc 0:1 12000000 u-boot.imx
reading u-boot.imx
343040 bytes read in 54 ms (6.1 MiB/s)
>>sf write 0x12000000 0x0 343040
ERROR: attempting write past flash size (0x200000)

I have no clue as how to overcome this error.Can somebody help me with this
error.


Thanks in Advance!

The size is here printed as a decimal number, but ...

...sf expexts hex input; so you actually passed 0x343040 which is
about 10 times the correct value.

You can easily avoid this problem by using the automatially set
variable "filesize" instead.

Try:

	fatload mmc 0:1 12000000 u-boot.imx
	sf write 12000000 0 $filesize

Please read *carefully* the i.MX manual. The SOC expects to read the
i.MX header at a specific address, depending on the selected media. On
most media (SD, SPI,..) this is 0x400. It is wrong to copy u-boot.imx at
the beginning of the flash.

And, as already remarked by Wolfgang, U-Boot uses hexadecimal values,
not decimal.

You are not erasing enough flash. Check the size, for a nitrogen quad I get:

-rw-rw-r-- 1 stefano stefano 363520 mar 14 10:03 u-boot.imx

You are erasing only 256KB, this is not enough.

Try:

sf erase 0 60000
sf write 0x12000000 400 ${filesize}

Best regards,
Stefano Babic

Yeah got it. Just specified the correct offset and converted the file size
to hex value.

Thank you!
