NSA320 reboot-after-power-loss

I've looked around several times in the forum for NSA320 I2C settings for this. I've found the 310 thread which I had hoped would be close enough, but I2C read shows the bits are already set in that register, so it must be somewhere else. No luck elsewhere on Google either.

Does anybody have the magic settings for these by any chance? If so, it would be a handy thing to add to the "wiki."

I've occasionally tried to pull up the original root file system from the MTD partitions to dig out the original Zyxel, but from what I can tell they were yaffs2 and I don't think any of the current kernels have support for this? And yaffs2utils package hasn't been happy with any of the MTD partition dumps I've tried to take. I kwboot'ed back to the stock uboot once, but either the kernel or the initramd images would not verify anymore, so stock FW wasn't able to boot and get me to the point where I could just copy off all the tools to a flash drive. (I still need to try using the backup partitions one of these days, but there is always something else to get done...)

I have an NSA320 with stock firmware and backup as I'm working on an OpenWrt patch as the other Kirkwood ZyXel NAS devices are already supported. What exactly would you like to have from the original firmware?

No dice, nothing on i2c-0 at that address

This is an old NSA320, not a 320s.

Ray, I was going to do the disassembly of the default Zyxel apps to try and dig out the settings, a-la https://forum.doozan.com/read.php?3,92579,92769#msg-92769. (Ironically no, safarik from that thread is not me.)

Safari Jack,

Ah. My mistake. The old NSA320 use normal sensor control. So try lmsensor to see if it helps.

Your best bet is using mtd backup files from someone, ie. Ray's, to restore to stock. And then dig in stock OS to find some scripts that deal with I2C.
