using ecos on UP3 kit

hi all :

I try following you ,I can add the UP3 to the ecos's depository and the UP3 and the Flash chip can found , the adding steps are below:

1) open the ecos.db and copy the content of the "NiosII target " ,and modify the package as :

package CYGPKG_HAL_UP3 {

alias { "Nios II common HAL"}

directory hal/UP3/arch/

script hal_UP3.cdl

hardware

description "

The Nios II architecture HAL package provides generic support

for this processor architecture. It is also necessary to

select a specific target platform HAL package."

}

target UP3_dev_board {

alias { "UP3 Development Board (Altera)" }

packages { CYGPKG_HAL_NIOS2

CYGPKG_HAL_SOPC

CYGPKG_ALTERA_AVALON_UART_COMM

CYGPKG_ALTERA_AVALON_JTAG_UART_COMM

CYGPKG_ALTERA_AVALON_UART

CYGPKG_ALTERA_AVALON_JTAG_UART

CYGPKG_ALTERA_AVALON_TIMER

CYGPKG_DEVS_ETH_SMSC_LAN91CXX

CYGPKG_ALTERA_AVALON_LAN91C111

CYGPKG_ALTERA_AVALON_LCD_16207

CYGPKG_ALTERA_AVALON_CF

CYGPKG_ALTERA_AVALON_AM29LV065D_FLASH

CYGPKG_DEVS_FLASH_AMD_AM29XXXXX

}

description "

This target provides the packages needed to run

eCos on a Nios II. In addition, components are included

which support the flash devices found on the Altera

Nios II development boards."

}

2) design a directory named "UP3" under the directoy "hal" ,and copy all of the content of the "nios2"

to the directory "UP3" , but I only rename the "hal_nios2.cdl " to the "hal_UP3.cdl" , the other files don't change at all.

So could I ask the ways are right or not?

meanwhile , I think the UP3 is a new template based on Niosii , so the UP3 is a new platform which has similar CPU---niosII as and the different periphal from the "Niosii dev board " offered by the "ecos " system HW, as a result the UP3 is a variant of the "Niosii dev board " , so I can move the new folder "UP3" designing as front to the \...\packages \hal\nios2 \ , If this, it is right or not?

then I have another question to consult you : what is the difference between the package "sopc" and "nios2" ?
