RE: what serial port type are Elan ports?

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.

serinfo:1.0 driver:5.05c revision:2001-07-08
0: uart:16550A port:3F8 irq:4 baud:9600 tx:11 rx:0
1: uart:16550A port:2F8 irq:3 baud:9600 tx:11 rx:0
2: uart:unknown port:3E8 irq:4
3: uart:unknown port:2E8 irq:3
4: uart:unknown port:1A0 irq:9
5: uart:unknown port:1A8 irq:9
6: uart:unknown port:1B0 irq:9
7: uart:unknown port:1B8 irq:9
8: uart:unknown port:2A0 irq:5
9: uart:unknown port:2A8 irq:5

Is this what you need?

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).

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
