[LinuxBIOS] questions about VSA on Gx2 plus cs5535??

[lihao]

Hi all,

I am running LinuxBIOS on gx2 and cs5535 platform. Now the code
begins to enumerate devices in northbridge.

And the code hangs just after prints out _do_vsmbios_.

I find the next function called close to that print is
_unrv2b((uint8 *)rom, buffer, &ileg)_, and it seems that cpu is in dead
loop.

I am thinking that maybe my linuxbios image is not correctly built. The step
I build image is divided into 2:

Firstly, I build out a _linuxbios.rom_ image;

Secondly, I use _buildrom_ tool from util directory to build
vsa2.bin and linuxbios.rom together out as the final image.

My flash is 512KB, so I put vsa2.bin at 0xfff80000, and
linuxbios.rom at another side of flash.

Is my step correct??

By the way, after I built out vsa image, it generates some other
images, which one should I choose? Including: vsa2.bin, olpcXXX.bin, some
vsms and so on..

Any advice would be well appreciated.

[LinuxBIOS] Console for an embedded system, Hex inverter needed

[Adam Talbot]

I have an embedded system with serial console, but its inverted.  I 
would normally use a hardware hex inverter chip, but currently dont have 
any sitting around.  Is there a way in linux/minicom to do hex inverting 
on the fly?  Or to capture and then convert?

minicom can capture.

Create a fifo on disk (mkfifo) have a software inverter read from it
and write to wherever, then use Alt-L or Ctrl-A L to activate
capturing in minicom. Use the fifo as capture file.
