Re: [coreboot] flash-chip (and compatibles)

2012-02-22 Thread Oliver Schinagl 
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-80-4I-S2AF-ND/2297800
http://search.digikey.com/nl/en/products/W25Q64FVSSIG/W25Q64FVSSIG-ND/2815931

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?

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.



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)

Winbond W25Q64CV

But Winbond's distributors AVNET and Digi-Key,

http://www.winbond-usa.com/winbondcms/Application/member/Distributors.aspx?partno=W25Q64CV

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

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.

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

Are these good to order a few for?



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

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...

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

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 
want?

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 :)
