Message: 51924    Is there any way to extract a version of u-boot off a board and create a u-boot.bin file?

Message: 51925    I've been able to do it using my jtag programmer (peedi by ronetix). Just hook it up, dump the address of flash you want and save it to a file.

Message: 51926    if you can write it, you can read it ... u-boot itself though does not support transmission at all, so you will need either a JTAG device or do it from Linux.  just dump the async flash memory region.  even easier if you've set up mtd partitions:

cat /dev/mtdblock0 > u-boot.bin
