[En-Nut-Discussion] Ethernut 1 and AT45DB64

[Daniel Ferrer]

Hi, this is my first post to this list.

I'm developing a small system using Ethernut 1.3 revH, using a custom 
board connected via expansion connector on board. The system controls 
some weather variables (humidity - temperature), and it stores measures 
in memory (and also it acts to control variables). Also it has a flash 
memory AT45DB64 that I want to use to store these measures.

My question is, can I use UFLASH filesystem / Nut OS device driver 
(devSpiAt45) for this combination of flash/board ? I've read 
http://www.ethernut.de/en/documents/ntn-6_spi.html
and it seems that I can use SPI spiBusAvr or platform independent 
bit-banging (spiBus0Gpio). I don't understand very well where I 
configure what GPIO pins are used for communicate with AT45DB64. 
Actually I've wired at flash:
CS/: PB0
MOSI: PB2
MISO: PB3
SCLK: PB1

By the way in case that this was possible, what version of Nut/OS do you 
recommend? I'm using 4.8.9.


thank you very much for your comments
