Hello guys,
After  dd if=barebox.bin of=/dev/sdb bs=512 and dd if=arch/arm/boot/uImage
of=/dev/sdb bs=512 seek=768 i am getting

Board: Freescale i.MX53 LOCO registered netconsole as cs1 eth@eth0: got MAC
address from EEPROM: 00:04:9F:01:B4:5B mci@mci0: No partition table found
Cannot reset the SD/MMC interface Malloc space: 0x7df00000 -> 0x7fefffff
(size 32 MB) Stack space : 0x7def8000 -> 0x7df00000 (size 32 kB) envfs:
wrong magic on /dev/env0 no valid environment found on /dev/env0. Using
default environment running /env/bin/init... Hit any key to stop autoboot:
1 phy0: Link is up - 100/Full T DHCP client bound to address
128.224.168.167 TFTP from server 128.224.168.11 ('zImage-loco' -> '/image')

Wasn't the board suppose to boot from sd card by default?

Also, i have another question. I want to replace

/* call start_barebox with its absolute address */
        r = (unsigned int)&start_barebox;
        __asm__ __volatile__("mov pc, %0" : : "r"(r));

&start_barebox with the actual address of the uImage practically to skip
all the barebox part and
boot only with the minimal CPU and memory setup. What do you think?
Regards,
George.
