And now I think I see why...
Before attempting to upload new firmware, both tda10045_fwupload and
tda10046_fwupload in tda1004x.c call tda1004x_check_upload_ok. This
returns -EIO if it couldn't find valid firmware or 0 if valid firmware
is found. Both the fwupload functions do:
if (tda1004x_check_upload_ok(state) == 0)
return 0;
which makes it look to me as if new firmware will never be uploaded
to the card if it already has valid firmware of an earlier version.
I may be heading in completely the wrong direction with this, but out
of interest I changed the above code to force a firmware upload, and
now get dmesg output:
tda1004x: found firmware revision 26 -- ok
tda1004x: waiting for firmware upload...
tda1004x: timeout waiting for DSP ready
tda1004x: found firmware revision 26 -- ok
So either it still isn't uploading, or the version I downloaded a couple
of hours ago isn't actually revision 29 at all. Is there any easy way
to check?
