4.4.97-1-ARCH wrong NAND chip timing in the DTS? NSA310 NAS

[arti74]

Yeah it was a pain for me for several days, I feel relieved now Thanks again for this great help. I think that my box is somewhat special...

The commands shows something:
$this->bbcode_second_pass_code('', 'sudo i2cdetect -l
i2c-0 i2c mv64xxx_i2c adapter I2C adapter
[rtorrent@alarm ~]$ sudo i2cdetect -l
i2c-0 i2c mv64xxx_i2c adapter I2C adapter')

Well as expected you have an i2c bus. $this->bbcode_second_pass_code('', 'i2cdetect 0') will show what address are responded to. $this->bbcode_second_pass_code('', 'i2cdump 0 address') will show you the data on that address.

Now what you have on you i2c bus, who can say, nas central doesn't really say, and that I find the best resource. But you could try monitoring the various numbers, and see what changes say when the case is closed, or the fan unplugged. But working out whats on the i2c bus will be a bit of work ...

eg, 10 minutes or so on my box gave the address for temp and fan speed, and $this->bbcode_second_pass_code('', 'i2cdump 0x0 0x50') gives the eth mac address ...

For example on my nsa325 now the case is closed, it says 36degC and fan at 625rpm.

Finished my rebuild this morning, and hour or so closing up the case, then rebuilding the beagle farm, and updating the little boxes.

Well its about numerology on numbers, e.g. the 0x00 and 0xff probably don't mean much, so probably not used. Similarly the repeating numbers, also don't contain much information eg. 80 80 80 5a 5a 5a 64 64 64. But why they have numbers is strange.

So the numbers that seem to have some content: 76 41 69 04, but as to what they mean, hard to say. Don't look like a mac address. Do the numbers change over time?

Did address 0x64 have anything in it?

$this->bbcode_second_pass_quote('', 'D')o the numbers change over time?
