i am compiling uclinux-2008R2 for an Atcom ip04 -i used the patches from astfin site-,

but when i load the images i got on the ship and start them ,i just get these 4 devices under /dev :

console log pts zero

although the rootfs partition is mounted properly and the network is working well -so the devices are recognized.

my dmesg gives this :

there is no 2008R2 release, so what version are you using ?

if you want different partition sizes, customize your board resources file.

review the documentation if you want to know about /dev and how it is managed:

http://docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:dev-management

as for the RTC, review your kernel settings in the RTC menu

thank you Mike ,

the version am using is : uClinux-dist-2008R1-RC8.tar.bz2

"f you want different partition sizes, customize your board resources file."

I said i already modified the partitions "kernel " and "filesystem".But am still unable to find where the partition "Romfs" is coming from ?

The problem is that i did made the image with bap's uClinux2008.mk makefile ,so i didnt chane anything ,b ut am still getting a not working image !!

I'm trying to understand - what is "bap's"? there is no such file as "uClinux2008.mk" in the official 2008R1 release.

If you are using a modified version of the build system or uClinux-dist - you need to go to who ever modified it for help - since we have no idea what they did. (Sorry)

We try to work with the astfin folks pretty closely - but they do things differently than we do.

the kernel output you showed told you where the romfs partition is coming from:

uclinux[mtd]: RAM probe address=0x3b00000 size=0x400000

Creating 1 MTD partitions on "RAM":

the uClinux ROMFS is automatically sized according to the file system you've embedded

baps is just an other uClinux -with some tweeks to fit the Voip devices ... -

uclinux2008.mk is a make file that downloads the uClinux source from your site ,then automaticly configurates it for the ip08/04 board (using bf532) ,among the modifications it does ,there is this section :

in file uClinux-dist/linux-2.6.x/drivers/mtd/nand/bfin_nand.c

{

.name = "linux kernel",

.offset = 0,

.size = 0x800000,

{

.name = "file system",

.offset = 0x800000,

.size = (CONFIG_BFIN_NAND_SIZE-0x800000),

}

Any way thank you for your answer - that's already a kind of help :-)

I told you before about making kernel update simple with the command : ipkg install vmlinux ,it's working now on stamp 537 board and kernel update is done successfully from uclinx console,i want to do the same with ip04 ,and as the offical -if i may call it so - release of the uImage_r2.ip08 image doesnt contain the necessary tools ,and when i compile by my self i always get missing devices ....

Mike ,

"the kernel output you showed told you where the romfs partition is coming from"

I am actually asking about the source file where the Romfs partition is declared or defined ;Or should i underdstand that this partition is automaticly created when i include the mtd-ram driver ?

it's the uclinux map, so just look at that driver if you want to know more about it
