Honored ContributorHi 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 Regards, --ScottHonored Contributor

Honored Contributori 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!!Honored Contributorwhat 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's post, http://forum.niosforum.com/forum/index.php?showtopic=3253 (http://forum.niosforum.com/forum/index.php?showtopic=3253)
