Hello.
I’m trying to flash u-boot bootloader to Embedded Artists board LPC2468 using lpcflash utility via USB cable with the following command:
lpcflash -vvv -i /dev/ttyUSB0 -f 12000 -w 0 -l /mnt/sda5/programs/mc\ images/u-boot.bin
and get next output:
Operation WRITE 0x00000000.

Looks like initialization stage goes fine, and then something wrong happens.
At this time board doesn’t signal anything, POWER LED glows green. ISP pin is set.
What kind of problem may be?
Thanks in advance
