Compatibility with Quartus 5.1 and Nios 5.1

Altera_Forum · ‎02-17-2006

Hi,

I'm a newbie and I'm wondering if the nios1.4 uclinux package can be used on a 2C35 Cyclone II device with Quartus v5.1 and Nios II v5.1 since the pdf hardware/software requirements doesn't include that device or those versions of the software.

If not, are there any workarounds to get uclinux on the board?

Thanks!

Hi Shindou,

You should try out buildroot and work on Linux, follow

http://forum.niosforum.com/forum/index.php?showtopic=3174 (http://forum.niosforum.com/forum/index.php?showtopic=3174)

The tools are independent of chips, boards, quartus2 and nios2 version.

Hi hippo,

Running ./build0207 for setting up the toolchain and getting the following error. I'm using gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-47.fc4)

Do you know what this error means?

It is building gcc in pass2. Please try, cd ~/buildroot, make menuconfig, toolchian option, disable c++, and make again.

You should select development tools packages when installing Fedora, and run "yum update" after installation.

thanks hippo,

Regarding step 5 -

cd ~/linux-2.6.x# generate nios2_system.h from ptf

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=your_system.ptf# config the kernel

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- menuconfig# compile the kernel

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc-

since the board is a 2C35, what should be used for your_system.ptf? will a linux_1C20 suffice?

thanks again!

The ptf is generated by the sopc builder.

It is used by hwselect perl script to generate the memory map, io ports address and irq number for nios2 uClinux.

It must match your hardware.

If you use altera dev board, you should find it in your kits, (eg altera/kits/nios2/components/altera_nios_dev_board_cyclone_2c35/system/...).

Or if it is a custom board, built it with the minimal components as in the guide.

Found it thx, though when I ran the make hwselect with the following options, I got the error below. I got a similar error when doing the make with the payload buffer and I think you mentioned in another thread to not use ROM?

Any modifications to the asm-offsets.c file needed?

(line 149 btw looks like:

DEFINE(LINUX_SDRAM_START, nasys_program_mem);

DEFINE(LINUX_SDRAM_END, nasys_program_mem_end);

)

Sorry, I pointed the wrong path in previous post. (I don't have any dev board)

Find it in page 1-9 in

"Nios II Development Kit Getting Started User Guide".

http://www.altera.com/literature/ug/ug_nio...ing_started.pdf (http://www.altera.com/literature/ug/ug_nios2_getting_started.pdf)

The ptf file should be

altera\kits\nios2\examples\verilog\niosII_cycloneII_2c35\standard\std_2C25.ptf

And there is a precompiled sof, which you can download to the board.

There is no need to edit the asm-offset.c .

You should have an option of sdram to "select a device to execute kernel from" during hwselect.

Altera_Forum · ‎07-07-2006

Thanks Hippo for the reply. It helped me out too. I had the same problem. Then I realized from reading your post that I had the wrong ptf file. I took the ptf file out of the components... which is WRONG ... as you pointed out we need to get it out of the examples. Which now the kernel and apps compile fine.

THanks.
