RE: what serial port type are Elan ports?

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 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.

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

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.
