Hi all,
I am trying to use the "w83977af_ir.o" driver in linux version 2.2.15pre17.
I am using the findchip utility that comes irda-utils-0.9.10
I have a motherboard with one of these chips on it.
This markings on the chip packaging are as follows
Winbond
W83977AF-A
(c) AM.MEGA.87-96
823CS281918902
According to the datasheet, the meaning of the last line is
823 - 1998 week 23
C - IC revision
S - assembly house : SPIL (?)
2 - wafers manufactured in Winbond FAB 2
81918902 - wafer production series lot number
(don't you feel better for knowing that ! :)
Findchip would not recognise the chip initially
but I found that there was some code that was commented
out, along with a message saying:
>if you have one of these chips, please mail me an output of
>"findchip -d -v WINBOND".
I am not sure who the author of the comment was, but
here is the findchip output as requested:
>bash# findchip -d -v WINBOND
>Probing for EFER at 0x03f0 ...
>hefras = 0x00
>EFER seems to be probed at 0x03f0
