[linux-audio-user] Getting the Echo Mona Laptop to work

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,
I'm trying to get my Echo Mona Laptop card to work, and I've done a lot 
of progress thanks to Giuliano Pochini and Ivica Ivo Bukvic, but I'm not 
there yet.
The alsa drivers written by Giuliano Pochini, though not currently part 
of alsa cvs, are reported to be working for the PCI version of the card. 
Echo (the manufacturer) has assured there is no difference in their 
windows dirver for the pci card and the pcimcia card, so the linux 
drivers should work for the PCMCIA card as well.
The current state:
-My machine recognizes the card properly as (using lspci):
04:00.0 Multimedia controller: Motorola: Unknown device 3410 (rev 01)

When hotplugging the card, the drivers are called correctly, but midway 
through loading, there is an error, and the drivers halt. The strange 
thing when loading is that the card reports a different serial number 
each time the card is loaded. This points to a data corruption problem 
somewhere.
This problem looks a lot like a problem discussed in the past on this 
list for the Hammerfall PCMCIA card, where people (Ivica in particular) 
were having trouble with the Cardbus bridge registers. The problem was 
solved by manually changing those registers.
I apparently have the same problem, since the registers for windows are 
different for the registers on linux (I checked the registers using 
hexdump -v /proc/bus/pci/02/01.0).
The registers are similar but have something like 15 values that differ. 
I tried changing the registers manually using setpci, but the problem is 
that when changing some values, other values I had already changed 
reverted to their old values, and some values could not be changed at all.
So my questions are:
Should the registers for windows and linux be exactly the same or is it 
normal to have variations?

How can I force the registers for the cardbus bridge to take on the 
values I get on windows?


Thanks very much,

Andr?s

PD. Here are the registers for windows:
