uClinux to personal NiosII board

[Altera_Forum]

hi, 

I saw the new release of uClinux for Nios on your site:  http://nioswiki.jot.com/wikihome/operating...ems/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/uclinuxdist)  And I try to port the uCLinux on my board according to the site, but failed. The board is design by myself, not the Altera series board. The hardware source now is:  EP1C12(FPGA), SDRAM(8Mbytes, 16bits data line), Flash(2Mbytes, 8bits data line), SRAM(512Kbtyes, 16bits data line), LED, button, UART. And I will expand LCD and key-button on it, have no Net peripheral.  The question is can I port uClinux on my board?  I try method your site provide, I think I should customize kernel by use "make menuconfig", but don&#39;t konw how to, cause I can&#39;t enter the custom menu by the site method. So I can&#39;t turn of the Net support and choose a series device(uart or jtag uart). And when I use "make" to creat image, there is some errors as follow: ----------------------------------------- include/linux/seccomp.h: In function `secure_computing&#39;: include/linux/seccomp.h:18: error: `TIF_SECCOMP&#39; undeclared (first use in this function) include/linux/seccomp.h:18: error: (Each undeclared identifier is reported only once include/linux/seccomp.h:18: error: for each function it appears in.) include/linux/seccomp.h: In function `has_secure_computing&#39;: include/linux/seccomp.h:24: error: `TIF_SECCOMP&#39; undeclared (first use in this function) In file included from arch/nios2nommu/kernel/asm-offsets.c:12: include/linux/sched.h: At top level: include/linux/sched.h:311: error: field `mmap_sem&#39; has incomplete type make[2]: *** [arch/nios2nommu/kernel/asm-offsets.s] &#38169;&#35823; 1 make[1]: *** [prepare0] &#38169;&#35823; 2 make[1]: Leaving directory `/home/gaobing/download/uClinux-dist/linux-2.6.x&#39; make: *** [linux] &#38169;&#35823; 1 [gaobing@tu194011 uClinux-dist]$ -------------------------------------------  And I can&#39;t run zImage on the Nios SDK Shell. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif   Need your help, ths! giantice 18th Jan, 2007

Which Linux distro do you use? 

Please install uClinux-dist again at your home dir, not under download dir. Please do it over again. You should not need costumize kerenl at the biginnig. Try "NON_SMP_BUILD=1 make" and post the last message. Please list your steps, if you still have problems.

You are very close to finish. 

You need to install bison package for ftpd, or you can disable ftpd.

Hi hippo, 

Thanks!  Is it the ftpd problem, so I can&#39;t build up the filesystem success?I have tried on the DE2 board, the problem was same.  How to intall bison package for ftpd?  I needn&#39;t net for my board, and how can I disable ftpd? Does it in "make menuconfig" ---> "[] customize Kernel Settings" (or "Customize Vendor/User settings" )?  Waiting for your reply, ths again! giantice 22th Jan 2007   --- Quote Start ---  originally posted by hippo@Jan 22 2007, 11:44 AM you are very close to finish. you need to install bison package for ftpd, or you can disable ftpd. <div align='right'><{post_snapback}> (index.php?act=findpost&pid=20750)  --- quote end ---    --- Quote End ---

Yes, you can disable ftpd with make menuconfig, Customize Vendor/User setting. 

 How to install bison package, depend on which Linux distro you use.

Hi hippo, 

I success make the Kernel and start "nios2-terminal" routine by your advice, thank you very much! It can really port uClinux on my own board.  But I found my Jtag Uart has some communication problems, so the uClinux debug can&#39;t run normally. How can I change the Jtag Uart serial to Uart(Rs-232) serial? I can&#39;t found the configuration choice in "Customize Vendor/User setting".  And I found the size of image file is too large for me. For example the Net application is not necessary for me. How can I exclude the application, reduce the imgae size, and get a minimal zImage file?  What&#39;s more, the flash on my board is 2MBytes, I found that after I try "elf2flash" to generate .flash file, the file generated is sum up to 2.7Mbtyes. So how can I reduce the .flash file size?  Looking forward to your reply, ths! giantice 22th Jan 2007   --- Quote Start ---  originally posted by hippo@Jan 22 2007, 02:20 PM yes, you can disable ftpd with make menuconfig, customize vendor/user setting.  how to install bison package, depend on which linux distro you use. <div align='right'><{post_snapback}> (index.php?act=findpost&pid=20753)  --- quote end ---    --- Quote End ---
