can't wait to fit ssd and do a kexec to transfer boot from SD to SSD and set up webserver + ftp server
<focus_well>
got me a BT line with 60mbit download speed and 16mbit upload speed - so it should work like a 'normal' webserver for two or three people use it at same time
<focus_well>
how tech changes with time!
<focus_well>
all for about 10W guessing.

what's the reason of using SSD rather than internal NAND? for speed?

slapin: I ordered two boards by waiting for 2 hours and placing 2 separate orders on different emails. You don't need to register - click on order and enter the card, email and address details. I think any excess you pay on one order is treated as a donation. That is why I placed 2 separate orders instead of one big order.

Nice. Have repeated JTAG hack I applied on OLinuxIno A13 on Cubieboard as well.
<hno>
slapin, Not today. Played a bit yesterday, but no sensible results yet. A bit difficult not knowing what really is on the flash.
* slapin
reads ONFI 1.0, trying to understand something important
<hno>
Will play a bit more with the Allwinner code later to try to understand what is on the flash.
<slapin>
hno: well, in latest code it reads always the same info, but full page, something is wrong with positioning on NAND
<slapin>
hno: you need to enter really large value for nand dump to see the difference
<hno>
slapin, Allwinner do use the controller a bit differently for reading, composing a chain of up to 5 commands in one go.
<hno>
slapin, how large?
<mnemoc>
hno: the hack to alternatve between mmc and jtag?
<hno>
mnemoc, yes, and having a wired 20-pin JTAG header.
<hno>
including system reset.
<mnemoc>
awesome!
<hno>
no messing with SD UART/JTAG breakout board and cables.

Coming, both of the final result with second SD + JTAG header, and an annotated picture explaining where to find the signals.
<hno>
need to figure out if a "nand disable" can be easily added as well. Poking with a metal piece at the nand pins during reset is not entirely comfortable.
<hno>
All the MMC0 signals are easily accessible at the back of the board in the array of 3x4 componens (beneath the Cubie logo)
<oliv3r>
mnemoc: btw, I do not approve or like paypal either. I just happen to have them, and if I could do without, i would. Google Checkout seems vailable (don't know if it's a paypal alternative)

hno: I'd prefer using command-by-command approach. Actually nand_sunxi almost never executes commands in parallel, and does not do batches. All this is fictional and overcomlicated, see the source.
<hno>
But you are right. The driver never ever uses SEND_CMD3/4.
<hno>
only 1 & 2.
<hno>
Really should wire up the logic analyzer and map things out a bit. This is confusing.
<slapin>
hno: please fix line 192 of sunxi_nand.c, and please test if you can, I'll be home only in 5+ hours.
<slapin>
where they get CMD2?
<hno>
There is 16 bits command in CMD and 24 bits in RCMD_SET and another 24 bits in WCMD_SET
<slapin>
ah, I see, I can put additional commands to RCMD
<slapin>
so they executed sequentally
<slapin>
but these don't have params, and just put on bus
<hno>
and up to 4 different command types.
<slapin>
weird
<slapin>
why they just put 05 always, without setting address?
<slapin>
hno: could you please see on logic analyser the real sequence they get on NAND bus?
<slapin>
hno: this sequence is interesting
<hno>
slapin, no idea. Hard to say what happens on the wires.
<slapin>
hno: it is important to see, because it might be wrong thing to do (they don't supply column for 05 and use e0 then 30 which is weird
<hno>
But it's also pretty clear you can wiggle byte per byte in CMD, even individual address cycles.
<slapin>
hno: yeah, we can, but a code will be simpler if we use CMD2
<hno>
yes
<slapin>
hno: hence I try to convince you fire up the logic analyser :)
<slapin>
I will be able too, but only on weekend as I explore brand new HP 16500C oscilloscope

hno: if NAND clock is 3MHz, why not?
<slapin>
hno: you don't need actual data, only first several bytes
<slapin>
hno: actually everything before 0x30 command
<hno>
slapin, because it has only 24K of trace memory, and uses 8 bytes per transition and we are probably looking at minimum 5 transitions per clock cycle.
<slapin>
hno: why 5 transitions?
<slapin>
trigger by we|re and everything should be fine
<hno>
Because databits and clocks arrive at different times. It's sampling all connected data bits for change.
<slapin>
hno: trigger?
<slapin>
hno: anyway, I think NAND clock can be reduced for that if this is an issue
<slapin>
but I think trigger will do...
<hno>
I can clock it externally, but that requires a single clock signal.
<hno>
I can use triggers to select when to start/stop sampling.
<hno>
and +/- offsets from triggers. to sample before/after the trigger.
<hno>
so theoretically possible to cover a whole page read by running it many times, but quite time consuming.
<hno>
clock speed is not a big issue. But sure, lower clock speed means lower sampling rate so should get less intermediary transitions as bits settle on their values.
<slapin>
hno: anyway, I'd try it, we just need several bytes...
<hno>
slapin, will try. But now trying to do some $$ work.
* slapin
