Hi all,

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:

Hi,

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.

Thanks,

Aneesha

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?

Suggestions?
