Hi Mike,
Firstly, thanks for all the effort in maintaining drivers for the
pvrusb2.
I recently acquired an HVR-1900 and now have it working with both
Ubuntu 9.04 and Slackware64 13.0, except for the IR Blaster. Using the
extract script from the 20091031 snapshot I was able to extract the
required firmware, but had a couple of problems in using the latest FX2
firmware.
The firmware for the HVR-1900 (From 1.2a driver CD) is now 16k in size.
To use this required two changes to the driver source.
1. The addition of the 16k flag for the HVR-1900 in pvrusb2-devattr.c.
*** 393,398 ****
--- 393,399 ----
.flag_has_analogtuner = !0,
.flag_has_composite = !0,
.flag_has_svideo = !0,
+ .flag_fx2_16kb = !0,
.signal_routing_scheme = PVR2_ROUTING_SCHEME_HAUPPAUGE,
.digital_control_scheme = PVR2_DIGITAL_SCHEME_HAUPPAUGE,
.led_scheme = PVR2_LED_SCHEME_HAUPPAUGE,
2. The firmware uploader pvr2_upload_firmware1 in pvrusb2-hdw.c checks
is hardcoded to check for an 8192 byte upload, causing a 16k upload to
fail. I changed this to use the actual size of firmware expected.
*** 1890,1897 ****
trace_firmware("Upload done (%d bytes sent)",ret);
! /* We should have written 8192 bytes */
! if (ret == 8192) {
hdw->fw1_state = FW1_STATE_RELOAD;
return 0;
}
--- 1890,1897 ----
trace_firmware("Upload done (%d bytes sent)",ret);
! /* We should have written fwsize bytes */
! if (ret == fwsize) {
hdw->fw1_state = FW1_STATE_RELOAD;
return 0;
}
Keep up the good work
Gary
