U-BOOT !!!!!!!!!!!!

Hi MFM,

==> flinfo
Bank#  1:   Size: 0 KB in 0 Sectors
 Sector Start Addresses:

It's time to implement your flash driver. If you have a CFI flash (and are _not_

using a data cache) you may want to try the default CFI flash driver. However,

depending on the command set and your flash geometry you may have to

disable the toggle bit polling (since it won't work with avalon).

Otherwise, you can grab an existing driver from another project. Please post your

flash configuration (and part numbers) and I'll see if there's one I can recommend.

Best Regards,

Hi MFM,

I'm trying to re-synchronize with this thread since I've been away, please excuse

the multiple posts ...

> what adresses to submit to mkimage, is the adress I've programmed u-boot at is

Always use the address where you want the image to be loaded and executed from.

In your case, SDRAM. There are two addresses you need to specify: (1) the load

address, and (2) the entry point address.

The load address is address where you want u-boot to copy the kernel image. It

is _not_ the addres where the .img file is loaded. You can put the .img file anywhere

in memory (flash, tftp into sdram, whatever). When you run bootm, you specify the

address of the .img, u-boot will then copy the kernel from the .img to the load

address. If the kernel image is compressed, u-boot will decompress as it copies.

The entry point address is the address that u-boot jumps to after loading the kernel

to its load address (and flushing cache, and disabling interrupts, etc). Normally, for

Nios-II/uClinux, the entry point address and the load address are the same. Since

the kernel start code is usually placed at the beginning of the kernel image. For

other architectures/kernels the entry point may actually be at some offset from

the start of the kernel image -- that's why you have the option of setting it with

mkimage.

Hope this helps.

My flash is an AMD AM29LV065D-120R 8 MB x 8 bits

Hi,

could somebody tell me where to get my flash base adress http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif

The fact is that when I looked in the standard design, I&#39;ve found that ext_flash is adressed at 0x00000000 and SDRAM at 0x01000000, but when I tryed to use the nios2-flash-programmer to upload the u-boot.flash (made with bin2flash) it&#39;s always failing with the 0x00000000 base adress, contrariwise, when I choose a 0x00800000 base adress, it works but the u-boot is apparently not in the user zone (I specified --location=0x00400000) since the green led of User il not lightened and u-boot not working.

I&#39;ve made that manipulation in the IDE, programmed flash in the user zone and it worked fine.

You should be able to use the existing flash driver in board/altera/common/AMDLV065D.c.

If you started with the ep1c20 configuration -- it would already be built for you. Otherwise,

you need to include the driver in your build -- copy the file into your board directory and

add it to your makefile. Then set the flash configuration macros in your configuration

header file. Here are the settings from other boards that use 065D:

# define cfg_flash_base 0xwhatever /* flash base addr */# define cfg_flash_size 0x00800000 /* 8 mbyte */# define cfg_max_flash_sect 128 /* max# sects per bank */# define cfg_max_flash_banks 1 /* max# of flash banks */# define cfg_flash_erase_tout 8000 /* erase timeout (msec) */# define cfg_flash_write_tout 100 /* write timeout (msec) */# define cfg_flash_word_size unsigned char /* flash word size */

Did I tell you (in some other thread) to stub-out flash_init? For some reason I thought you

were using an Altera stratix 2 development board -- which uses the LV128.

Hi Scott,

you are right, I&#39;ve been using a Stratix II board, but all I&#39;m asking now for is for a Stratix Pro Edition 1s40

Hi,

seemingly my flash base adress is 0x800000, don&#39;t ask how I get it, I just tried it and it&#39;s fine, where to get that information remains then a mystery to me.

hi scott,

- u-boot works fine but when i type flinfo this is what i get

==> flinfo
bank#  1:   size: 0 kb in 0 sectors
  sector start addresses:
==>

- when i try to save my variables with saveenv:

==> saveenv
saving environment to flash...
error: start address not on sector boundary
==>

ps. i&#39;m using a stratix pro 1s40 board

Do you just develop SW in NiosII system? Who develops NiosII in Quartus/SOPC builder?

All informatioins about modules of NiosII, including flash, SDRAM..., can be found in SOPC builder. The file-- <NiosII Name>.ptf records all information about "HW" of NiosII system. Yes, of course the BASE ADDRESS.

Then all your SW works should deal with the information about "HW".

---------------------------------------

1. uClinux

nios2linux.h (which is generated according to *.ptf automatically) deals with the information.

Any other drivers could take a reference from nios2linux.h or add "BASE ADDRESS" in DRIVER.c/.h directly.

---------------------------------------

2. u-boot

<u-boot-src>/include/configs/"board".h should deal with the information manually.

Hi,Scott

My flash is AM29LV160DB and it locates in 0x800000 ,how can I choose a flash drive for it.

I use the u-boot-1.1.4 and choose the PK1C20 board . but the flash used is AM29LV065D-120R 8 MB x 8 bits.

how can I modify it to meet my Cyclone Board?
