Hello,
I'm currently developing a device driver for Triple Communication
Controller. The diver managed two modes (asynchronous or synchronous)
because each serial line could be independently configured as synchronous or
asynchronous.
My request is concerning the configuration of the baud rate. I

The problem is that it pushing the single character *buf = c; but could not
send it through and as result is never breaking the bottom loop - the flag

Hi,
We are looking for a compactFLASH driver for Linux which runs over
PPC750. The
device we are using is Hitachi's 128MB FLASH part no - HB28B128C8HSR.
We are
planning to interface this directly without any IDE controller or PCMCIA
interface.
How do we go about writing a driver for this ? Is t

Hi Steven,
I have read the mail listed below on the "lists.linuxppc.org" website.
It looks like you are the right expert who can help me solving my
problem.
The embedded linux can't detect my SANDISK CF card. I choosed the
EXT_DIRECT mode (CF's TRUE IDE mode), but now I am not sure if my design

There are some things you should change:
First, PPCBoot is a dead project; development has been discontinued
more than half a year ago. For new development the successor project
"U-Boot" should

Hi,
I installed a ppcboot and a linux 2.4 on a MPC8260ADS card.
Now, I am working on a custom card such as an MPC8260ADS card. The difference
between those two cards is the ethernet: my custom card has two ethernet port,
and uses two LXT971A.
So, I compile a ppcboot for 8260ads. PPCBOOT can't
Li,
Why are you combining an SPI driver with an ATM driver? Shouldn't you
create two separate drivers instead?
