GCC 7.4.0 release candidate

2018-11-30 Thread Sebastian Huber


Hello,

a GCC 7.4.0 release candidate is available. I would like to update the 
RSB to use GCC 7.4.0 for all targets which currently use GCC 7.3.0. This 
will change the type int32_t from long to int.

Chris .. my before and after for ticker.exe are:

[joel@rtbf64c b-mpc8260ads-before]$ cd ../b-mpc8260ads
[joel@rtbf64c b-mpc8260ads]$ powerpc-rtems5-size `find . -name ticker.exe`

  867922364  145288  23   393cc
./powerpc-rtems5/c/mpc8260ads/testsuites/samples/ticker.exe

I am doing a complete build from scratch -- reconfigure, build, etc. Are
you doing that as well?

Patch pushed.

State of Wired Networking on BeagleBone Black

2018-11-30 Thread Joel Sherrill

Hi

I was asked about the state of networking on the BBB and thought it
was support. But when I looked at libbsd, I didn't see anything obvious
with am35xx in the name. When I googled, I found the GSoC 2015
student who did this work. He mentions the file
freebsd/sys/arm/ti/cpsw/if_cpsw.c here:

http://ragustechblog.blogspot.com/2015/06/porting-driver-from-freebsd-to-rtems.html

which is not in the current rtems-libbsd source tree.

BBB does have wireless support in the config file but nothing obvious for
wired.

What's the status?

Thanks.
