Hi, I folllowed the instruction on nanoxdemo for ipaq
to install the ROM file system on ipaq. I'm sure it
is installed correctly, and here is what it is
look like:
RedBoot> fis list
Name FLASH addr
Mem addr Length Entry point
(reserved) 0x50000000 0x50000000 0x00040000
0x00000000 RedBoot 0x50040000
0x50040000 0x00040000 0x00000000
RedBoot config 0x50F80000 0x50F80000 0x00040000
0x00000000 FIS directory 0x50FC0000
0x50FC0000 0x00040000 0x00000000
ROM_DISK 0x50F00000 0x50F00000 0x00080000
0x00000000
Here is the program I wrote for testing file system.
#include <pkgconf/system.h>
#include <pkgconf/kernel.h>
#include <pkgconf/libc.h>
# include <pkgconf/io_serial.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <cyg/kernel/kapi.h> /* All the
kernel specific stuff */
#include <cyg/fileio/fileio.h>
#include <cyg/infra/diag.h>
#include <sys/time.h>
int main(void)
{
FILE *fp;
printf("Mount ROM file system\n");
if (mount("0x50F00000", "/", "romfs") < 0) {
printf("... failed\n");
}
printf("... success.\n");
fp = fopen ( "/hellodata", "w+");
if (fp != NULL) {
// do something
}
else {
perror ("error:");
return -1;
}
return 0;
}
I used gdb to remote run this program in the RAM of
ipaq, and Here is the result I got:
(gdb) continue
Continuing.
Mount ROM file system
... success.
error:: No such entity
So, it seems ROM file system is mounted correclty,
however I cannot use it. Please tell me what is wrong.
thanks,
Weilong

You can't write to a romfs - it is a
Read Only Memory File System
^^^^ ^^^^
If you want to be able to create files, certainly in Flash,
you'll have to have a different type of file system.

I'm trying to use jffs2 file system, there is
a prebuilt image from embedded linux demo for ipaq,
so I installed it on redboot. But how to
add jffs2 package into ecos?
One more question is that if I'm going to use
ramfs, how to do the configuration for ecos
and redboot? Does the prebuilt image of redboot
for ipaq already included the ramfs?
thanks,
Weiong

At this time, JFFS2 is only supported by Linux. We hope to offer
JFFS2 support in eCos sometime in the [near] future, but there is
no schedule for this.
Note: getting a customer who might be willing to help "support"
the development of JFFS2 on eCos could possibly speed this process.

So what kind of file system is supported by Ecos?
And where is the documentation about how to use it?

I'm trying to use jffs2 file system, there is
a prebuilt image from embedded linux demo for ipaq,
so I installed it on redboot. But how to
add jffs2 package into ecos?
One more question is that if I'm going to use
ramfs, how to do the configuration for ecos
and redboot? Does the prebuilt image of redboot
for ipaq already included the ramfs?
thanks,
