hi fmcmurra,

which evalutation board are you using? there are several "nios ii" eval boards.

porting is quite simple ... so even if a port does not exist, you can usually just

use an existing nios ii board configuration with a few nips 'n tucks to the config

header file and have a working u-boot. see:

Hi Scott,

I don&#39;t have a problem porting u-boot to the NIOS II eval. baord (I&#39;ve done at least a couple dozen ports for ppc,arm,mps,etc.). I just didn&#39;t want to do it if someone else has already.

I pulled the src tree from the psyent.com download area and compiled a couple of boards from the src trree. So my dev. enviornment appears to be ok.

Forgive me for being a noob to NIOS2, it won&#39;t be for long.:-)

I was under the impression there was only one eval board for the NIOS2. The rest are called devleopment boards. the one I have is based on the epc12 (cyclone?).

I&#39;ve looked at the code in the u-boot source tree I downloaded form the above site, but none of them appear to be enabling the CFI flash driver (CFG_FLASH_CFI_DRIVER) is this correct?

The flash chips on my eval board are CFI compliant so I&#39;m going to use that instead of flash.c. Are there any problems with this CFI driver. The one in the regular u-boot tree works just fine so I&#39;m hoping this one does too.

Another question I have:

Which board should I use for my port? Should I use one of the bords in the psyent or the altera board directory.

Like I said I&#39;m an old hand at Linux and u-boot (started when it was ppcboot) but I&#39;m new to the FPGA&#39;s. So please be gentle if I appear to be asking stupid questions.:-)
