board the terminal is blank, i don't have MINI2440# in the console serial.

thanks in advance.

You are running minicom?  Also, you know about the issue with u-boot and
256M?

Read throught the comments on buserror's site.

hi,

andromeda 
i have tested with putty and is a same

any idea ?

andromeda 
i don't know the issue for u-boot

davef 
Everybody with 256M go to this site:

http://bliterness.blogspot.com/

and read the comments found at the bottom of each posting that buserror has
made.  

For example, the recent kernel there are 7 comments.  Now, go to the one
where he announces new uboot for 256M etc and read those comments.

The new u-boot doesn't work in RAM. Somehow the interupt code that I added
to get USB working makes it crash when launched at an arbitrary address.

To make it work anyway, edit include/configs/mini2440.h and disable the
interupt #define. That will build you a u-boot that works in ram, but
without usb. Once that is in RAM and runs, build another u-boot to flash to
NAND...

but the file mini2440 doesn't exist i have s3c2440.h so
there many define , its a define INTERRUPT_ ...

because i have recompile uboot with disable the define and i have error .

how can i load another u-boot from current u-boot ?

thanks.

Thanks in advance

how can i load another u-boot from current u-boot ?

If the current u-boot is in NOR you can load another into flash. I left
Supervivi in NOR and only put u-boot into NAND flash.

You could change from one to the other by just flicking the switch from NOR
to NAND.

To get u-boot or anything else into NOR you will need the JTAG adapter and
the programs for JTAGing on the downloads page.

Don't know about errors in compiling u-boot because I have tried to do that
. . . yet.

is ok now 

1)Boot from NOR Flash
2)Download
and Run uboot-nand2k.bin after compiling from the git tree.
3)Do nand scrub,createbbt.
4)!!IMPORTANT!! Reset the board and boot into NOR flash.
5)Select the Download Vivi option and download uboot-nand2k.bin
6)Reset into NAND Flash.
7)uboot boots up then run "dynenv set 40000"
8)run saveenv
9)You should see a Writing to NAND.

Setup is complete

thanks
