Altera_Forum--- Quote Start --- originally posted by alex824@Apr 7 2006, 06:28 PM hi hippo:1, i find the kernel linux.2.6.x more steady then other kernel.because i run some
app on the 2.6.x is fine,but other kernel weill died.
2.i want to use 2.6.x vmlinux in cfi flash, so i use follow command:
# creating .flash file for the project
elf2flash --base=0x00000000 --end=0x07ffffff --reset=0x0 --input=vmlinux --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 --sof=flash.sof
i program flash succesed.
i restart my dvb but boot kernle failed. if i use command "nio2-download -g vmlinux" ,the kernel boot successed.

Maybe you should repost it over the uclinux forum, and other experts may help out. the telnetd (and ftpd, too) used to be invoked by inetd. so you won't see a telnetd in ps. you can debug these servers without inetd , using the -debug option. you should play and learn on Linux PC before you do it on nios2. you may try out an old slackware, which use inetd.ps - Altera_Forum--- Quote Start --- originally posted by hippo+apr 9 2006, 04:25 am--><div class='quotetop'>quote (hippo @ apr 9 2006, 04:25 am)</div>

can you tell me how to install "bison" on my build machine ?

--- Quote End --- if you use DE2, the ptf and sof are on the DE2 support CD, DE2_System/DE2_demonstrations/DE2_SD_Card_Audio/nios2_0.ptf and DE2_SD_Card_Audio.sof you don't need QuartusII on Linux. check your nios2-linux-uclibc-gcc in ~/buildroot/build_nios2/staging_dir/bin , if you have them, then check your PATH variable, follow step4 in the guide. PS, this thread is getting too long, please post your questions on the uclinux forum.
