RE: what serial port type are Elan ports?

[Ed Vance]

Hi Alex,

Thanks, I think the Elan SC520 is all I need. I don't know if the other
chips in the family have the same bug. 

There is a conflict between the Elan work-around and the 16C654 UART. It
looks like the work-around causes it to drop transmit data. If I can know
for sure the detected type of the Elan's ports, then I can shield all other
UART types from the work-around with a quick type field check without losing
the benefit of the work-around. 

Suggestions are welcome.

Best regards,
Ed

Elan ser. port bugs? was Re: what serial port type are Elan ports?

I'm massively using the Elan SC520 ser. ports, but w/o the standard serial 
driver. I'm using a special driver since I need to "talk" a rather odd 
protocol on the serial line.

Would you please shade some light on how and when the 520' could be loosing 
data? I didn't found anything in the datasheets. Is it only relevant when you 
use FIFOs? At higher baud rates? Is it reagrding (h/w) handshake?

I saw that Alex sent you the needed info but
if you need more h/w info regarding the SC520 (or SC4x0) please speak up.

TIA. Salut, Jörg

At least the SC410 has the same bug. Unfortunately I don't have a
ready-to-run system at the moment, so I cannot make the tests right now.

Thanks for the good information.

Do you think there is a need to look at the UART type on any more of the
Elan based systems if the SC4X0 is also detected as a generic 16550A?

Ed

RE: what serial port type are Elan ports?

[Ed Vance]

Hi Alex,

Yes, it is exactly what I was looking for. Thanks very much.

Robert Schwebel has indicated that the Elan silicon bug is also in the SC410
chip. If you or somebody else have a ready to run SC4X0 based system, please
send me the first ten or so lines of output from the following command so I
can see the UART type that was detected for the SC4X0's serial ports:

	more /proc/tty/driver/serial

Thanks again,
Ed

Hi Ed,

Well, here's the output from my stock Red Hat 7.3 (2.4.18-3) system, running
on an AMD ElanSC520-133AC Alpha Rev 1A from 1999 (antique, aint it?).  Its
sitting on an AMD Aspen Microcontroller Customer Developer Platform Rev 1.2.

Hi Ed,

I've got an SC520 dev board here actually.  I can get that output to you
tommorow (have to scrounge up a power supply et al).

RE: what serial port type are Elan ports?

[Alex Pavloff]

Elan Sc3x0?
Elan Sc4x0?
Elan Sc520?

I assume you mean the 520, if you really want to find the UART for the SC3x0
I might be convinced to plug in a hard drive to one of my many SC320s lying
around and let you know.

what serial port type are Elan ports?

[Ed Vance]

Hi,

I need to know what UART type the serial driver detects for the two built-in
serial ports on the AMD Elan Microcontroller?

Would some nice person who has an Elan based system please send me the first
ten lines of the output of the following command?

	more /proc/tty/driver/serial

Thanks in advance,
Ed
