Hello,
The First Evaluation is going on and I here I would summarize all the
progress
that the project has made in the first Phase.
1. The major progress is the completion of the I2C adaptation layer in the
libbsd
along with the iicbus driver imports. The v4 of the driver [1] has
been tested to be
working with the bbb-i2c driver patch [2]. After the RTEMS driver is
updated in the
master, the adaptation layer will be mergeable.
2. I am getting EDID reading from the imported tda drivers. I have checked
this using
the ti_i2c driver but now as we have an updated version of the driver,
I'll pull this all
with the adaptation layer and will continue from there.
3. I found a sample app from the freebsd mailing list, that draws a basic
shape on the
screen. I have made it a standalone app with only single source and
have tested it
to be working with the FreeBSD. The only issue with the code is that
it uses mmap
and RTEMS doesn't use mmap so I'm rewriting the app with pread and
pwrtie on
to write to the /dev/fb0 directly. This app work is ongoing.
Next Up:
1. merge the ported TDA driver and using it with the adaptation layer.
2. Import and port the fbd dirver to create an fb0 device.
3. complete the sample app and convert it into a libbsd sample app to test
the device.
Thanks,
Vijay
