Nice.

What are the differences?


Difference between ARM and PowerPC? None that I am aware of.



Are standard blobs built with any FDT compiler usage?


I think the blob FDT itself is platform independent.

Re: [PATCH] Use a hash file for GCC only

In a way, I do like that this shows the different gcc-newlib versions
we use. It might be nice to add a bit of organization to this hashes
file and/or documentation of the procedure for adding/removing
entries.

Maybe it makes more sense to have a separate file for each version
being used, e.g. a gcc-4.8.3 hash file, gcc-4.9.3, gcc-6.0.1, etc?
That should make it easier to maintain the hashes.

I'll leave it to Chris to decide if this is a suitable compromise.



This seems to have stalled and I have had to push the change to fix 
builds on FreeBSD 11.0 so reverting the change is not possible.


Please apply this patch. We can look at further improvement as future 
refactoring work.


After the comments in this thread I sent an alternative patch that 
removes the hash file:


https://lists.rtems.org/pipermail/devel/2017-March/017102.html

Which one do you like?

Re: Interest in applying for GSoC under RTEMS

2017-03-07 Thread Gedare Bloom

Hello Anshuman Chhabra,

Complete https://devel.rtems.org/wiki/GSoC/GettingStarted first, and
review the material available through
https://devel.rtems.org/ticket/2899

Not linked yet in the ticket are last year's projects:
https://devel.rtems.org/wiki/GSoC/2016/USB%26EthernetRaspberryPi
https://devel.rtems.org/wiki/GSoC/2016/LowLevelPeripherals%26SDcard

To work on an RPi project it would also be good if you can boot on one
of the currently supported boards.

I have RTEMS specific support functions which wrap the base FDT 
interfaces to make it simpler to use in applications when interfacing to 
hardware. Included is an fdt command to list (ls), read (rd) and write 
(wr) plus some utility functions like polling for a bitmask to be valid. 
The command is a useful tool when integrating software for hardware 
described in the FDT or just debugging new hardware, for example FPGA 
register sets. I have seen hundreds of #joel scripts in the past few 
years. The work also includes a faster search of the blob when then are 
thousands of entries.


I just need time to get the work included in RTEMS with tests.

Interest in applying for GSoC under RTEMS

2017-03-07 Thread Anshuman Chhabra

Respected Sir(s)/ Ma'am,

I am Anshuman Chhabra, a third year undergraduate in Electronics and
Communication Engineering from the University of Delhi, India. I would like
to be a part of GSoC under RTEMS and I am interested in the Raspberry Pi
Projects, specifically adding support for the Pi Zero W.
I have a lot of programming experience (very little of which is reflected
at github.com/anshuman23) as I have been primarily involved in programming
for research work in the fields of mobile networking, machine learning and
the Cloud. I have three IEEE publications as accepted papers at conferences
in India and the USA. I am proficient in multiple languages but enjoy
coding in Python and Ruby the most.

How should I go about discussing my ideas before the application portal
opens? Also, could someone point me in the right direction to get started
with the specifications of the project?

Thank you for your time,
Warm Regards,
Anshuman Chhabra

Re: Issue with 'rtems_shell_wait_for_input' function

2017-03-07 Thread Sebastian Huber

Hello all,

I made few changes to the fileio test to run NFS using libbsd. The test 
compiles and when i run it on qemu NFS is initialised.

The test starts with the 'rtems_shell_wait_for_input' function which returns 
RTEMS_UNSATISFIED so the test quits as soon as it begins. I read this means the 
terminal related attributes could not be set. When i bypass this function to 
directly start the test it works fine. Im not sure this is a bug or some 
problem with my configuration. Any help with this issue is appreciated!


The serial driver doesn't implement the set attributes device handler 
properly and returns an error.

FreeBSD:


https://www.freebsd.org/cgi/man.cgi?query=fdt=0=0=FreeBSD+11.0-RELEASE+and+Ports=default=html

This allows the use of unmodified FreeBSD drivers on PowerPC and ARM
