Hi guys,
I’m still trying to make my ISDB-T tuner run in my development board with A20 soc. I'm trying to backport media-tree siano drivers to kernel 3.4.75. With a few changes in Makefiles to fit new directory structure and disabling IR I could compile and load the modules. No errors reported on loading or compiling.
But as I don’t know enough DVB structure, something still wrong. When I scan without antenna, no problems. But when I plug my antenna and scan starts on frequency with signal presence, I have
DVB3_EVENT_FE_LOCK and DVB3_EVENT_UNC_OK messages and a lot of MSG_SMS_DVBT_BDA_DATA messages. These messages stops only when I remove usb tuner.
Can you guys give any tip or documentation to clarify this DVB section? I’m trying read DVB docs for now.
Thank you !
Best regards,
- Roberto
