I am a Windows programmer. I also develop for Windows Mobile, Android and BlackBerry. I am using an IP Camera. It has the usual cgi scripts on it which I can access to control the camera functions. What I would like to do is browse the files on the device and perhaps upload my own cgi scripts onto the device. With a mobile device such as Android (etc) I can use certain development tools such as Eclipse. What tools are there availble for a Windows Developer to access and connect to an IP camera that has embedded Linux installed?
What would be required to support reading the CPU temperature in a MVL6.0 Z530 distribution?
Are there kernel configuration option requirements?
Are there modules that need to be included in the RFS?
Does anything need to be started in the init to support this capability?
I have a OMAP3530 board on which our custom linux disro is working. I installed X server and matchbox into it. I just started matchbox, it is working fine but it is taking time (around 1 mins) to load. Please let me know how to reduce it.

On a different distribution udevadm has a different version, newer by about .20 subrevision numbers.
On that distribution I can execute a udevadm info request using arguments like --query=property --name=/dev/ttyS0.
I cannot get a similar result at all using the udevadm on my MVL6.0 distribution. The version shows as 124 whereas I have a version 157 on that other distribution. Rebuilding udevadm appears to require a lot of utilities to be installed.
Any suggestions, I merely need the udev information for a USB serial device because I need to monitor that during runtime. These devices can be unplugged or reinserted and my application needs to follow this. At present I'm considering that I'll have to iteratively check and ls -1 /dev/ttyUSB* result and then look backwards in my system log (dmesg), and that isn't the way I should be doing that.
I am working with MVL6 and I want to create image using only custom collection. The custom collection contains binary RPMs of the different packages.
I have create a project and copied all the recipe files in 'collection/custom/recipes/<respective package directory>' directory of the project. Then I have run command 'source setup.sh' and 'bitbake -D default-image'. But I got error 'ERROR: IO Error: file 'conf/bitbake.conf' not found'. I have also verify that 'BBPATH' environment variable is already set. Then also it is giving this error.
I don't know why this error comes. Please help me out to resolve this issue.
Thanks in advance.
Using the default build for MVL6.0 on Intel ATOM Z530; my root login immediately gives me:
"-sh: can't access tty; job control turned off"
tty is /usr/bin/tty, executing this gives me "/dev/console"
If I "echo 1 > /dev/console" I see that echo out on my default console. Also if I "echo 1 > /dev/tty0" I see that echo out on my default console.
My boot line is:
bzImage console=tty0 noinitrd ip=0.0.0.0:::::eth0:off rw root=/dev/sda2
General Google searches seem to indicate that busybox is either build incorrectly, or there's some other problem associated with busybox.
My normal shell commands work; however if I execute /bin/sh or just enter "sh" I get
sh: can't access tty; job control turned off
Seems to be a protection thing when I see that; however ... I'm root.
Privileges for /dev/tty, ttyS0, ttyS1, ttyS2, and ttyS3 are all:
crw-rw---- whereas for all others tty0-63 are crw--w---- More »
Using MVL6.0 for Z530 I've built a version to boot from RAM disk using the Quickstart initramfs recommendations.
I installed grub2 onto a compact flash and end up at the grub> prompt.
From there I can issue a kernel line to point to my vmLinuz and boot.
There are two problems.
1.) I do not know how to configure grub to just boot and not stick at the prompt; unless there's an error seen in the grub.cfg or other files; hence why it does that.
2.) I do not know how to properly issue the kernel or boot lines so that I can get it fully booted.
"kernel /boot/vmLinuz root=/dev/sda ro" - tells me it can't mount the file system and I end up at the root of the RAM FS
"kernel /boot/vmLinuz root=/dev/sda1 ro" - caused a panic and stuck there about the time it was going to try and mount root
"kernel /boot/vmLinux root=/ ro" - same as the first one, can't mount the file system and drops me to "/" for the RAM FS. More »
I use this to get to devshell:
bitbake -c devshell linux
Then, from the devshell, I do:
CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-mips CALL scripts/checksyscalls.sh <stdin>:1421:2: warning: #warning syscall marker not implemented <stdin>:1425:2: warning: #warning syscall trace not implemented CHK include/linux/compile.h LD init/mounts.o mips-montavista-linux-gnu-ld: unrecognized option '-Wl,-rpath-link,/user/oneil/core/pjmips/tmp/staging/mips-mv-linux/usr/lib' mips-montavista-linux-gnu-ld: use the --help option for usage information make: *** [init/mounts.o] Error 1 make: *** [init] Error 2
Anyone else seen this? What's the resolution?
