How big is your flash chip? How big is the image you are
burning?
Do you have a serial cable attached to the machine and
the correct baud rate set?

I don't know about anyone else but the dental floss idea didn't
work at all for me, the floss interferes with the pins.
I had this idea on how to remove the chip easily, but I
haven't tried it. Just get some strong epoxy and glue
onto the top surface of the flashrom something to
act as a handle. After it's dry, use that to pull the
chip out.
JB Weld might work.

Look at Config.kernelimage.lb in targets/arima/hdama.

That is 128k.
In the MB Option.lb there ROM_SIZE
You can change that to ROM_SIZE=524288
So Fallback will use 128k, and Nomal will use 384k.

hmm.. so i commented out the 'normal' section of my target Config.lb and
changed the buildrom line to only build the fallback image, but
the generated rom file is now 131072 bytes instead of the expected 512k.
Any ideas?
danke ;)

All,
We've managed to get into linux on epia-sp using our modified
V2 linuxbios source. Next week we'll be cleaning up the
code for release back to the project. There were a lot of real
puzzlers we had to figure out.
Missing pieces include:
1) DDR init not using SPD values, controller settings taken
from stock bios and are specific to our particular DDR module
2) Size isn't detected correctly
3) VGA BIOS doesn't exist, however it might not be needed
4) Cache init code taken from V1 epia-m tree, so it's lots of
inline ASM which is probably against the ideals (romcc)
>From my point of view the worst thing about linuxbios is the
crippling lack of documentation. Document this thing better and
you'll see more developers jumping on board, I think.

Just a couple hours ago we figured this out, it was related to
incorrect settings of the VLINK control registers. We copied values
from award and now it's stable.
Thanks--

We've got epia-sp almost into linux fully, but RTL8139 (eth1) or the
VIA 3065 (eth0) don't work properly.
Interrupts are occuring as expected on ethernet packets. We're trying to
work with the RTL8139 for now which is a card plugged into the epia-sp.
It's able to act as a pci bus master. I suspect something about the PCI
isn't working, like the card isn't able to dma into host memory or
something similiar.
Inside linux drivers/net/8139too.c inside function rtl8139_rx_interrupt
if ((rx_size > (MAX_ETH_FRAME_SIZE+4)) ||
(rx_size < 8) ||
(!(rx_status & RxStatusOK))) {
rtl8139_rx_err (rx_status, dev, tp, ioaddr);
printk("here2 rx_size = %d\n", rx_size); // (DA)
return;
}
The interrupt service routine is exiting because rx_size is always 0. This
is the size of the received packet I think.
A similiar problem is occuring in the 3065 ethernet. We're failing to do
something within linuxbios that's preventing pci devices from functioning
properly.
Does anyone have any suggestions? I'm hoping these symptoms are familiar.
Thanks--
Dave
I am pretty new to LinuxBIOS. I tried building Iwill's
dk8s2 motherboard by
buildtarget Iwill/dk8s2
cd Iwill/dk8s2 && make
Tried on four platforms but met different problems. I
feel surprised and would like to ask some questions
here. And hope someone can anwer.
1. Do I need to compile it on a machine with IWILL
DK8S2
motherboard?
2. Do I need to use a specific kernel version, gcc
version?
Thanks a lot.
