[Altera_Forum]

I can not access the web link given in the forum http://www.pysent.com/download (http://www.pysent.com/download)  

 can anyone send the code to me?  my email is: scut_ak@163.com  Thanks in advance.

I used the u-boot-1.1.4 and choose the 1C20 board and modify the file ./include/configs/DK1C20.h and ./include/configs/DK1C20_standard_32.h  

 then back to root dir of u-boot and type the following commands:  make CROSS_COMPILE=nios2-linux-uclibc- DK1C20_standard_32_config  make CROSS_COMPILE=nios2-linux-uclibc- all  then the following error occur: [hgjw@localhost u-boot-1.1.4]$ make CROSS_COMPILE=nios2-linux-uclibc- DK1C20_standard_32_config ...

Hi scut_ak, 

I've sent you the u-boot binary and source files. BTW the right adress is http://www.psyent.com/download/ (http://www.psyent.com/download/)

Hi scut_ak, 

<div class='quotetop'>QUOTE </div>  --- Quote Start ---  I used the u-boot-1.1.4[/b]  --- Quote End ---   Use the files I sent you by mail (from http://www.psyent.com/download/) (http://www.psyent.com/download/)) instead of that version.

Hi, MFM 

 Thank you for your help, I have recieved it .

[Altera_Forum]

Hi, MFM 

 I only modify the file EP1C20.h in include/configs/ directory to fit my Cyclone Board (the FPGA chip is EP1C6),  Then type the following commands  make EP1C20_config make  then produce the u-boot elf image  and in nios sdk shell I download the system.sof then   nios2-download -g u-boot and it download to the address 0x1FC0000  my sdram address is begin at 0x0 (8M) my flash addess is begin at 0x800000 (2M)  how to modify the address in which the u-boot image download to ?   warm regards.

Hi,MFM 

 The output as I type the following command    [SOPC Builder]$ nios2-download -g u-boot Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Processor is already paused Downloaded 98KB in 2.8s (35.0KB/s) Verifying 01FC0000 ( 0%) Verify failed between address 0x1FC0000 and 0x1FCFFFF Leaving target processor paused /cygdrive/c/u-boot-src/u-boot  How to change the download address?  In the file \include\configs\EP1C20.h ,I have found the following infomation related to the load address:# define CFG_LONGHELP /* Provide extended help*/# define CFG_PROMPT "==> " /* Command prompt */# define CFG_CBSIZE 256 /* Console I/O buf size */# define CFG_MAXARGS 16 /* Max command args */# define CFG_BARGSIZE CFG_CBSIZE /* Boot arg buf size */# define CFG_PBSIZE (CFG_CBSIZE+sizeof(CFG_PROMPT)+16) /* Print buf size */# define CFG_LOAD_ADDR 0x0/*CFG_SDRAM_BASE*/ /* Default load address */# define CFG_MEMTEST_START 0x0/*CFG_SDRAM_BASE*/ /* Start addr for test */# define CFG_MEMTEST_END CFG_INIT_SP - 0x00020000 # define CFG_HUSH_PARSER# define CFG_PROMPT_HUSH_PS2 "> " # endif /* __CONFIG_H */   In fact my CFG_SDRAM_BASE is set to 0x0 already, but it still does not work as espected.  I do not know why?  can anyone give some hint ?  Thanks in advance.

Hi,MFM 

 We know that when we use the command "nios2-download -g u-boot" then it download the elf format image into sdram automatically and here the addess  0x1FC0000 was not assigned by me in the above command.     I mean where to specified this addess in the u-boot source code.  Thank you for your replay .  Warm Regard.  scut_ak    --- Quote Start ---  SOPC Builder]$ nios2-download -g u-boot Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Processor is already paused Downloaded 98KB in 2.8s (35.0KB/s) Verifying 01FC0000 ( 0%) Verify failed between address 0x1FC0000 and 0x1FCFFFF Leaving target processor paused /cygdrive/c/u-boot-src/u-boot

The default load address is set by link script. 

Check your Makefile to find out the link script. You can check the load address with, "nios2-linux-uclibc-objdump -h u-boot", it will display in VMA/LMA fields.

Hi scut_ak, 

 > my sdram address is begin at 0x0 (8M) > my flash addess is begin at 0x800000 (2M) > > how to modify the address in which the u-boot image download to ?  There are several ways to do this ... but if you&#39;re just hacking at the 1c20 configuration, then just modify the TEXT_BASE macro in:  board/altera/ep1c20/config.mk  If you have 8M starting at 0, I&#39;d recommend:  TEXT_BASE=0x007c0000  ... that will provide plenty of space for your image if you want to experiment with additional u-boot features (e.g. NFS, CompactFlash, IDE, whatever).  Regards, --Scott

Hi,smcnutt 

 Thank you for your replay .  I have successfully ported the u-boot to my board.  I change the TEXT_BASE to 0x300000 and it work OK.  warm regard  scut_ak
