To extract the firmware for the Opera DVB-S1 USB-Box
|
||||
you need to copy the files:
|
||||
|
||||
2830SCap2.sys
|
||||
2830SLoad2.sys
|
||||
|
||||
from the windriver disk into this directory.
|
||||
|
||||
Then run
|
||||
|
||||
./get_dvb_firware opera1
|
||||
|
||||
and after that you have 2 files:
|
||||
|
||||
dvb-usb-opera-01.fw
|
||||
dvb-usb-opera1-fpga-01.fw
|
||||
|
||||
in here.
|
||||
|
||||
Copy them into /lib/firmware/ .
|
||||
|
||||
After that the driver can load the firmware
|
||||
(if you have enabled firmware loading
|
||||
in kernel config and have hotplug running).
