Im thinking now of building an ARMlinux system from scratch based on the
SA110-21285 combination.
Id like to build a system, comprising the following:
SA110
21285
256Mb SDRAM
Serial I/O (RS232)
16bit audio I/O
Ethernet (10 baseT)
LCD panel (small, maybe 320x200 mono)
4 arrow keys and "select" on a control pad
I havent had time to investigate the 21285 much yet, but would be
grateful if anyone cold point at a datasheet for it (I now have the
SA110 datasheet)
I'd like to keep as much of the system (in fact, all of the PCI) running
at 3.3v (does the 21285 allow this?) and am lookig for chips that can
provide serial, 16bit audio, ethernet, and some method of driving an LCD
panel.
Does anyone have a source of information regarding these type of devices
(preferably on the 'net)? I discovered the ESS SOLO-1 chip which looked
ideal until I realised it ran at 5V only... as to ethernet, serial, and
an LCD driver, I have no leads yet. Obviously, chips which have working
drivers under armlinux and arent obsolete would be nice :)
Thanks for any help, and if anyone knows of a newsgroup where I can get
info on building computer systems, that'd be cool too :)
