Now please present your story (meaning Craig) - how
long have you been
actively working toward your respective goal? What do you have to
show so far?
I have been working with osmocom-bb since around 2010, dabbling in porting
layer1 to nutt-xand starting 2-3 years ago working more earnestly on
understanding layer1 and porting it to fernvale. I have also worked on getting
fernly (a small system for experimenting with similar commands like osmoload
has) working on other mediatek chips like mtk6261, 6735 and 6737.
I have osmocom-bb firmware loading via fernly which has a working serial driver
(fromfernly project) so I can get debugging out of devices like fernvale. I
have more recently started to port the txburst command from uboot for the
sciphone dream g2 (mtk6235) back to osmocom-bb. I have been studying the
sources I have for mediatek devices and see many similarities and patterns that
should work for fernvale(6260), sciphone (6235) and newer chips such as 6735
and 6739.
So at this point I have some work that others did to transmit a burst on a
specific ARFCN. This works on uboot for sciphone dream g2 and for some reason
doesn't work when I port it back to osmocom-bb to start as a basis for layer1.
Do you have an equivalent source of knowledge for
MTK's DSP?
As far as I know there is no direct knowledge/sources for MTK's DSP but I
haven't quite gotten to the point where I needed to know just yet. This is a
very part-time endeavor for me so I do what I can.
There are some other people working on various aspects of mediatek devices
including trying to get into the DSP. We generally chat/share things on matrix
at #postmarketos-lowlevel:disroot.org
Cheers,
Craig
