Hi,
I'm new to LB, and after studying the list archives for the past week,
I've started working on getting LB installed on yet another Geode GX1
board. This system is actually a MaxSpeed MaxTerm 230, an old thin
client system that had been surplussed. The board inside was
manufactured by DTRI (www.dtresearch.com), and is model WBTG v1.1. The
WBTG has a 300Mhz GX1, 64MB of on-board DRAM, and 8MB of on-board
flash. It uses the CS5530 southbridge, an NS PC97317 SuperIO, and an NS
83815 10/100 Ethernet.
Since the CPU, southbridge, and SuperIO are the same as the Eaglelion
5bcm, I have started with that target. And my initial LB image,
complete with FILO, basically works! At least, it passes the smoke test.
Questions/issues thus far:
1) IRQ questions. I got the error about copying the IRQ table, and I
know I can fix this by using an uncompressed image. But that leaves me
with a few questions:
a) Does using an uncompressed LB image preclude having a failsafe
image, due to uncompressed image size? Not a problem for me, just curious.
b) How can I create an IRQ map for this system, or do I not worry about
it? This machine was built to only run WinCE, so I can't take the stock
BIOS, boot Linux, and do any investigating.
2) When initializing the IDE on the CS5530, LB reports "missing
enable_resources", even though a few lines prior, it looks like it
assigns the proper I/O range for IDE. What does this mean? (See
attached LB output.)
3) I have several uses in mind for these boards, if I can get more of
them. Some uses would involve using the audio and VGA, both of which I
know are problematic. I think the VGA part I can do, but what about
audio? Is "VSA" required to initialize the audio? I guess what I'm
wondering is, what's the minimum LB has to do before Linux can see (and
use) the audio. FWIW, this board has an NS LM4548 audio chip, which I
assume is a support chip for the XpressAudio? Or better, maybe DTRI
decided to scrap XpressAudio and this chip is standalone... that would
make me happy. :-)
Thanks to everyone on the LB team, it's clear from the archives that you
all are really dedicated. And thanks to Hamish for the GX1 work in LBv2.
