How to porting u-boot to my own board?

Hi Scott,

It make me headache.

My Flash progrmmer (Microtronix official Providing) can not work under Nios SDK Shell. But it works fine in Nios IDE.

I re-generate my flash-programmer design, but the same.

The infomation under Nios SDK Shell is (I copy .sof to u-boot directory)

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

> $ nios2-flash-programmer --base=0x0 --input=u-boot.flash --sof=mtx_nios_dev_board_cyclone_1c20.sof

nios2-flash-programmer: Launching Quartus Programmer to download:

mtx_nios_dev_board_cyclone_1c20.sof (here download to my FPGA)

Send <64> failed.

Unable to synchronize with target.

......nios2-flash-programmer: Error opening target hardware[/b]

OR

<div class='quotetop'>QUOTE </div>

......nios2-flash-programmer: Error opening target hardware

......nios2-flash-programmer: Unable to open flash device after successfully communicating with target.[/b]

--- Quote End ---

Is there any difference between nios2-flash-programmer in Nios SDK Shell and Flash Programming in Nios IDE?
