u-boot about 2c35

Hi iriver,

> i want to run u-boot on 2c35,but it seems to only support

Once I receive the 'official' Nios II 6.0, I'll be updatng u-boot -- and 2c35 board support

will be added (along with various other updates) In the mean time, you can use an existing

board configuration as a starting point. Just use the 1C20 configuration for example ... do

the following:

1. Update the macros in include/configs/EP1C20.h to match your hardware design.

Use the information from you ptf file or SOPC Builder.

2. Either find and use an appropriate flash.c file ... or just modify flash_init to return a non-zero

value without probing the actual flash. If you choose to modify, your flash utilities won't work.

But you'll have everything else ;-)

3. Make the EP1C20 configuration:

$ make EP1C20_config

4. Make u-boot:

$ make

It&#39;s pretty easy (with some help form Scott) to do. I did it for the eval board in no time at all and even added support for the real UART, not the JTAG UART...

Hi iriver,

> when i make,2 errors happen

What are the errors? And where did you get the u-boot source code from?

Hi iriver,

Please see: http://forum.niosforum.com/forum/index.php...indpost&p=16044 (http://forum.niosforum.com/forum/index.php?act=st&f=18&t=4093&hl=&view=findpost&p=16044)

Or you can get a (cygwin friendly) tarball from: http://www.psyent.com/download (http://www.psyent.com/download)

Please find it mirred at nios wiki,

http://nioswiki.jot.com/wikihome/operating...-src-050811.zip (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/dasuboot/u-boot-nios2-src-050811.zip)

i build the u-boot successfully,but when i run the command:nios2-download -g u-boot

these happen :

Download 99kb in 1.3s<76.1kb/s>

Verifying 018C0000<0%>

Verify failed between address 0x18C0000 and 0x18CFFFF

Leaving target processor paused

i build on EP2C35,my sdram address is 0x04000000

can the u-boot run on sdram?

i want to run it on sdram first,but the 0x18C0000 means what?

what is the problem?

thanks!!

what is the sdram address of your 2c35? 0x04000000+0x02000000 in std_2C35.ptf ?

it is different from 1c20 board.

so you have to change

board/altera/ep2c25/config.mk

TEXT_BASE = 0x05fc0000

you need to update include/configs/EP2C35.h ,too.

see tschmelcher&#39;s post,
