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
