Hello, everyone I want to use u-boot on my board. I have two questions. 1. Before I use u-boot on my board, I just try to compile u-boot first. So, I follow the readme file. I use make PK1C20_config make all But there have errors. <div class='quotetop'>QUOTE </div> --- Quote Start --- In file included from /usr/include/sys/unistd.h:9, from /usr/include/unistd.h:6, from img2srec.c:61: /usr/include/sys/types.h:106: conflicting types for `int8_t&#39; /usr/include/stdint.h:38: previous declaration of `int8_t&#39; /usr/include/sys/types.h:108: warning: redefinition of `int16_t&#39; /usr/include/stdint.h:39: warning: `int16_t&#39; previously declared here /usr/include/sys/types.h:110: warning: redefinition of `int32_t&#39; /usr/include/stdint.h:40: warning: `int32_t&#39; previously declared here /usr/include/sys/types.h:112: warning: redefinition of `int64_t&#39; /usr/include/stdint.h:45: warning: `int64_t&#39; previously declared here make[1]: *** Error 1 make[1]: Leaving directory `/cygdrive/d/My_Project/MtxCyclone_uBoot/BootLoader/u-boot-1.1.3/tools make: *** [tools] Error 2[/b] --- Quote End --- I search the forum and find the answer given by smcnutt. <div class='quotetop'>QUOTE </div> --- Quote Start --- This looks like the sources directly from sourceforge.net ... this tree assumes you have an appropriately configured native gcc and shell environment -- which doesn&#39;t come with the nios2 toolchain 8-P The easiest thing to do is get the source tree from http://www.pysent.com/download (http://www.pysent.com/download) -- this tree has certain "nips & tucks" made to build cleanly with the default nios2 toolchain (under cygwin) -- and it&#39;s more up-to-date than the sourceforge tree (WRT Nios-II, the sourceforge tree has been lagging by several months).[/b] --- Quote End --- But I can not access the web link.

Hi LiangYi, > But I can not access the web link. Can give me the right link or the files? The link is correct and working. Sadly, the problem is probably because you are in China, and your government prevents your free access to the Internet. It would be a pleasure to send you the source code. Please send me a PM with a valid email address that can accept a 1.6 MB attachment. And please feel free to distribute the code among your colleagues. Regards, --Scott

Does the link fail? > Can you tell me detailed about TEXT_BASE, and how to set it? TEXT_BASE is set to the address where the .text section is located. This is the section that contains all of your code. In u-boot you would typically set this to a location at the top of your sdram (so the bottom of your sdram is available for a kernel). > make[1]:*** No rule to make target &#39;mtxkit1c20.c&#39;, needed by &#39;.depend&#39;.

Check your make target in the top level Makefile -- and always make distclean after moving stuff around ... you might have some artifacts (like old .depend files) in your source tree. Your top level target should call mkconfig with the appropriate arguments: mkconfig BOARD ARCH CPU DIR VENDOR Based on your post, you should have: mkconfig MTXKIT1C20 nios2 nios2 mtxkit1c20 microtronix > I run saveenv and re-run, but the warning still appear. Why? The saveenv command writes your environment variables to a non-volatile memory ... which is normally a parallel flash device. If you see the warning after running saveenv, the save operation failed. This is usually because you don&#39;t have your envirnonment setup properly ... or your flash implementation is broken. Please let me know the following: What type of flash are you using? (type and geometry) What is its base address? What is the value assigned to CFG_ENV_ADDR? Regards, --Scott

Hi LiangYi,

> You said I can use flash.c. So, I browse flash.c(include /common/flash.c). I found AMDLV065D.c
> just have both parts of two flash.c files. So, I think I can change AMDLV065D.c to my use.

I was referring to the flash.c files found in most board-specific trees. Most of the supported
boards (see the boards directory tree) contain a file named "flash.c" -- this is a common
convention in u-boot. The boards that show support for the AM29DL323 are for example,
RPXClassic, RPXlite_dw, and some of the esd boards (esd/common). Those trees will
probably have the code you can use.

You probably still have the flash programmer design loaded. Try reloading your application sof.

> Communication port must be specified.
> Use openport <port> to configure the communication port

This is probably your problem ;-)

Hi Scott,

I have tested cfi_flash.c.
I add<div class='quotetop'>QUOTE </div>
--- Quote Start ---
#define CFG_FLASH_CFI_DRIVER# define CFG_MAX_FLASH_SECT 71 /* Max# sects per bank */# define CFG_MAX_FLASH_BANKS 1 /* Max# of flash banks */# define CFG_FLASH_CFI[/b]

to my board.h file. When I build u-boot, it has error in function flash_init().
<div class='quotetop'>QUOTE </div>
--- Quote Start ---
cfi_flash.c:343: undefined reference to 'monitor_flash_len'[/b]
--- Quote End ---

Is monitor_flash_len the u-boot image file size?
What can I do about it?

Furthermore, My flash is 16-bit width, should I define FLASH_CFI_16BIT in my board.h.

Thanks,
LiangYi

Hi LiangYi,

> cfi_flash.c:343: undefined reference to 'monitor_flash_len'

Did you modify cfi_flash.c? My version has no reference to monitor_flash_len at line 343 -- it shows
up in the statement at line 348. Just as a sanity check, your code should look like this:
#if (CFG_MONITOR_BASE >= CFG_FLASH_BASE) && (CFG_MONITOR_BASE <= CFG_FLASH_BASE + CFG_FLASH_SIZE) flash_protect (FLAG_PROTECT_SET, CFG_MONITOR_BASE, CFG_MONITOR_BASE + monitor_flash_len - 1, flash_get_info(CFG_MONITOR_BASE));# endif
Check your config macro definitions. This should not even be compiled, unless you are trying
to run u-boot out of flash.

> Furthermore, My flash is 16-bit width, should I define FLASH_CFI_16BIT in my board.h.

No, it is defined in include/flash.c. The CFI code determines the width automatically.

Hi Scott,

I have added cfi_flash.c to my u-boot, re-compiled u-boot and it can run in sdram.
Then, I download the u-boot to my flash at 0x0 using Flash-Programmer. I reload the app sof file, open NIOS2-SDK Shell, run nios2-terminal. Nothing happen.
I think that nios2-terminal start with jtag-uart, but not from uart. I do not know how to do next step?

Give some info.

Thank you.

Great!

> I download the u-boot to my flash at 0x0 using Flash-Programmer

How did you create the flash file? Typically, you should do the following:

$ elf2flash --base=0x0 --end=0x7fffffff --input=u-boot --outfile=u-boot.flash --flash=<Uxx>
$ nios2-flash-programmer --base=0x0 --input=u-boot.flash --sof=<xxx.sof>

> Shell, run nios2-terminal. Nothing happen.
> I think that nios2-terminal start with jtag-uart, but not from uart.

When you run out of sdram, do you use the jtag uart ... and did you see the command prompt?

If everything works with download/go to sdram, you most likely have a problem with the u-boot
image stored in flash (either the flash file is incorrect ... or flash memory is not correct).

Hi Scott,

A strange problem, so annoyed.
In Nios SDK Shell, I type command you say under my u-boot directory.

$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20

Respond : elf2flash: No reset address provided on the command line, and none found in the ELF file
Then, I add.
$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20 --reset=0x0
Respond: elf2flash: Boot copier file name required, error generating Flash file, exiting
I redo, add
$elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20 --reset=0x0 --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec
Respond: elf2flash: read error: File not found: c:/altera/kits/nios2/component/altera_nios2/boot_loader_cfi.srec
elf2flash: Error reading boot copier

Does elf2flash need all parameters?
My path C:\altera\kits\nios2\components\altera_nios2\boot_loader_cfi.srec is right, but elf2flash can not find the file. Why?

Hi LiangYi,

> $elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20

elf2flash is appropriate if you boot from an epcs, ... sorry for misleading you. When you are using
parallel flash with u-boot, bin2flash is what you want (since the u-boot make will generate a
binary image). E.g.:

$ bin2flash --base=0x0 --location=0x0 --flash=U20 --input=u-boot.bin --output=u-boot.flash

> $elf2flash --base=0x0 --end=0x1fffff --input=u-boot --output=u-boot.flash --flash=U20 --reset=0x0
> --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec

u-boot does not require the boot copier ... it will relocate itself to its run-time address.

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 ---

OR
<div class='quotetop'>QUOTE </div>
--- Quote Start ---
......nios2-flash-programmer: Error opening target hardware

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

It is the same application ... but the parameters may be different.

This is the error infomation displayed in Nios SDK Shell. But It runs OK in Nios IDE.
I do not know what is wrong. Have you ever seen this problem?
I will try again.
