It seems libtbm-dumb and libtdm-drm should work fine as you said.
But, sometimes we face the unexpected problem when testing new target
device.
Could you check if any TBM or TDM error logs are in your board? you can
check them with "dlogutil TBM" and "dlogutil TDM".

Hello, thank you very much for your mail.
I am using beaglebone black singleboard computer, which is based on
TI's AM335x SOC.
This board supports Linux mainline kernel wirh board-specific patches
and my kernel version is mainline 4.4
When I read your wiki section, I thought that I don't need to port the
backends because the libtbm-dumb and libtdm-drm are for the modules to
support the platforms which provieds standard drm interfaces like my
board.
Anyway, thanks a lot your help and I will check whether ENABLE_PP is
set or not in my kernel.
Best regards.

I will find what make it get freeze later.

TBM and TDM backend are Tizen HAL modules dependent on Hardware and
its kernel. So you would need to implement these HALs - TBM and TDM
backends. You can refer to below porting guide.

If your board uses mainline kernel which never include in-house code
then you could use libtbm-dump and even libtdm-drm(by disabling
ENABLE_PP config) packages below by installing them on your target.

What hardware and Linux kernels are you using? If you give me more
details about your env. then I may give you more advices.
Thanks,

I'm not that well-aware of display-related technologies or recent
Tizen changes.
