about memory problem for uclinux....

hi all

I have upload a music file(xxx.wav,about 700kB ) to uclinux from my PC ,and I got very long error messages on uClinux . such as following:

it seems memory not enough..............

anyone have met the same problem ?

Have any ways to solve it ?

    Maybe you can try init+sash of uClinux-dist instead of all in busybox.

    It should save some memory usage.

    http://nioswiki.jot.com/wikihome/operating...ems/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/uclinuxdist)

    You may also try NFS root. (but I didn&#39;t test that yet)

    Or, the hardware approach, check if you can replace the SDRAM chip to 32MB, (ie 16Mx16).

    It has the same pins out, but address A12. You can check if there is a PCB trace reserved for A12. Or you can find some spare pin out of 2C35.

    Hi hippo :

    Thanks for your reply, I think NFS maybe the effective way,I will do it quickly.If I&#39;ve done it, I will let you know!

    hi hippo

    if i use cfi flash.when i have built kernel zImage to support the Jffs2 .

    Dose i must execute some steps to program flash (include zImage.flash & sof.flash)? such as following 

    cd arch/nios2nommu/boot#  Creating .flash file for the FPGA configuration
sof2flash --offset=0xC00000 --input=$SOPC_KIT_NIOS2/examples/verilog/niosII_cycloneII_2c35/standard/standard.sof --output=standard.flash#  Programming flash with the FPGA configuration
nios2-flash-programmer --base=0x00000000 standard.flash#  Creating .flash file for the project
elf2flash --base=0x00000000 --end=0xffffff --reset=0x0 --input=zImage --output=ext_flash.flash --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec#  Programming flash with the project
nios2-flash-programmer --base=0x00000000 ext_flash.flash

    in my csae, i have only 4M flash for DE2.

    Can i only create a MTD partition to store "my_image.flash" around 4M space?

    Because my sof.flash is big around 2.1M ,and i don&#39;t program it to flash.

    Thx !

    Hi jay_1025,

    The DE2 is different from other Altera Nios dev boards.

    The DE2 &#39;s fpga configs from EPCS16 (not CFI), is 2MB.

    The sof is not written directly to EPCS, it will be converted to RBF (raw binary file).

    The compress configuration data of 2C35 size around 300K-400K, typically.

    So you will have around 1.6MB unused space in EPCS16.

    You should store zImage after the RBF on EPCS.

    That is, you should use EPCS first.

    Then the CFI 4MB will be available for jffs2.

    Another issue, busybox takes more memory on MMU-less arch.

    So I move to simplified init and sash in uCLinux-dist. (!!!)

    http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist)

    It will save more memory.

    hi hippo

    Thank you for reply.

    But i haven&#39;t sloved to erase my flash memory yet. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

    when i use "nios2-flash-programmer" command to erase flash memory under sdk shell, then i got some info such as following

    i can see my target borad is UP4 under SOPC Bulider.

    Do you know how to solve it ?

    PS:i am using QII 5.0 sp2.

    Jay,

    You really need to upgrade your tools... You should be using, at least, Nios II/Quartus II 5.1SP1.
