I'm the lead maintainer of pramfs. Pramfs is a fs for non volatile in RAM developed by Montavista. It results as an open source supported project but actually the last their official support is really old. Does anyone if there is a real support in Montavista products? It'd would be great to merge any improvement/new features if they added them. Does anyone if Montavista provide an fsck? I'm currently planning to write it, but since I don't want to reinvent the wheel, I wonder if Montavista provides it. Any support/help/feedback is welcome. I'd like to hear especially some Montavista guy.

My embedded system running montavista CGE can perform a halt without poweroff via directly issuing the /sbin/halt command or by running shutdown -H or by running init 0 which actually calls /sbin/halt. The problem with this for me is my processor board is in an enclosure with a battery backup system and no direct way to force poweroff, there is no power button in the design. If somehow the halt gets called without the poweroff option, the system is hung until the battery dies.
Is there a way to prevent linux from issuing the halt command or alternatively always enforcing poweroff? I have tried removing permissions on halt, which prevents calling halt directly, but I still want to be able to reboot/poweroff or otherwise use /sbin/shutdown. I looked for a "nohalt" option in the kernel parameters but it doesn't appear to apply to x86_pentium4 architecture that I am using.
Here is more information on my environment:

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?
Do anyone have an idea on how to fix the error - "timeout waiting for hardware interrupt" while sending the CMD0 and CMD8 to the SDHC card.
The SDHC driver which I got it with the Montavista CGE 6.0 linux 2.6.32 is not working for our custom board.
It was giving the error -84 Illegal byte sequence while sending the CMD8 (CMD0 was success with this). Then I changed the SYSCTL register for the clock settings and could remove the error.
Now I am getting this new error -110.
Please let me know if someone already faced this problem and knows how to fix it.
I have to port montavista-pro5 on SBC(x86 architecture).
Please give some input on how to proceed.
As per my understanding,Linke other Linux variant (For example u-buntu) we can directly intstall it on SBC.
We have 256MB of non-managed NAND flash.
JFFS2 would work, and we have experience with it in a NOR environment, but legend has it that its performance suffers as the device size increases.
YAFFS seems to get the most Google hits, but is not part of the Linux mainline.
UBIFS seems to be in the Linux mainline.
LogFS also gets some press?

I have to work on finger print scanner(Suprema umf3040). Can any one tell
me the compatible finger print SDK for this and also any useful links about
interfacing finger print scanner with ARM9 samsung s3c2440?
I am new to embedded linux but have experiance working on Ti's ARM7 which does not include linux programming. Now I am into ARM9 and working on dealing with linux device drivers and application development.Can anyone let me know and guide me getting some hands on practical experiance and also what is the best way for starting any project at hand since linux is large so does the programming.Everything looks very complicated for me.
Any guidance will be helpful.
Thanks in advance,
