flaschip (and compatibles)

[Oliver Schinagl]

Hey list,

I want (in the far? future) play with coreboot on my new board, an Asus 
M5A97 (900 series amd chipset) thing. Having it not even build into my 
case yet, I was wondering if you guys know what a compatible flash chip 
is. I have an 8 legged little socketable chip on here, with the 
following markings:

MXIC
b111376-12G
MX25L3206EPI
3F204500

So far I found the best results from google with the MX25L3206EPI 
labeling but the few links I got where mostly in chinese and the 
datasheet links where the 'pay' kind.

Any pointers what I can ask for when I go to my local hardware store so 
I can order 3 or 4? Shouldn't be too expensive right? Anything in 
NL/BE/DE I suppose would work best :)

I did find a pdf that was somewhat interesting:

http://www.msc-ge.com/download/pcn/macronix/pcn-10-037.pdf

it basically mentions/confirms it's an SPI/serial based 32Mb flash, 
dunno if that can help me find a pin-compatible chip :S

hello oliver

MX25L3206EPI-12G

that chip is not special at all and can be replaced by (almost?) any
25-series flash chip with the same package (300mil 8-PDIP) and voltage
rating (2.7 - 3.6V).
of course there are corner cases, but in general there should not be a
big problem with other vendors. if you have found an offer that suits
you, you could ask us again...

That is very interesting; I see conrad (http://www.conrad.nl) has loads 
of eeproms for about 1E for sale. I'd have to figure out details first, 
but things like EEPROM 25LC040/SN Microchip EEPROM 25LC256-I/SN 
Microchip EEPROM 25LC1024-I/SM Microchip etc etc seem like part nummers 
that should be what I'd

Oh never mind, these are all miniscule (kbit range) parts. Sorry for the 
noise.

I was pointed to this one: A25L032-F 
http://nl.farnell.com/amic/a25l032-f/memory-flash-spi-32m-8dip/dp/1907085

(There's also a Q version, which I don't think is what I'd want).

http://nl.farnell.com/jsp/search/browse.jsp?N=202454+110164787+110184599&...

Are these good to order a few for?

I haven't found a 64Mbit chip yet, so I hope I could use a linux kernel 
as payload using a 4MB one (the current 32Mbit)

Correct. Q is a WSON package which does not fit at all. Make sure you
buy farnell nr. 1907085 and nothing else. A25L032-F is indeed the
accurate manufacturer's part number, if you order somewhere else.

Winbond W25Q64CV

But Winbond's distributors AVNET and Digi-Key,

http://www.winbond-usa.com/winbondcms/Application/member/Distributors.aspx?p...

only have SO-8 in stock, and you wanted DIP. You could look for
adapters, but then you must do some soldering.

http://search.digikey.com/scripts/DkSearch/dksus.dll?site=us&lang=en&...

AVNET only have SO-8 stock in Asia. You'll have to pay import fees
and tax. Digi-Keys f-ing website barfs some idiotic error at me
whenever I try to use it nowadays.

You can buy DIP from bios-repair.co.uk, but they only have the older
revision W25Q64BVAIG. For once they don't charge more than AVNET&co
in single quantity.

http://bios-repair.co.uk/Products/EEPROM/SPI-SerialFlash-EEPROM.html

Click Winbond, then there's W25Q64BVAIG 64Mb PDIP top left in the
product listing.

Having trouble ordering from several webshops in Europe (The only want 
to send you parts if you order in huge quantities or if you are a 
company) I've found the following at digikey in the US.

http://search.digikey.com/nl/en/products/SST25VF032B-80-4I-S2AF/SST25VF032B-...
http://search.digikey.com/nl/en/products/W25Q64FVSSIG/W25Q64FVSSIG-ND/281593...

I know they are 8-SOIC but have ordered (and received)  8-SOIC -> 8-DIP 
pcb's so can easily convert between the sockets. I guess these should 
work just fine?

Hi,

First of all, welcome to the community and thanks for your interest in coreboot!

Most DIP8 chips should work, but I would recommend at least 1MB(8MBit)
parts, so your payload would fit comfortably.

If you plan to use big payloads (anything involving a Linux kernel),
you should get 4MB or 8MB parts.

You can find flash parts on http://bios-repair.co.uk, but there are
many sites where you could find them, including ebay.

Cheers,
Cristi
