Re: [PATCH 2/2] bsp/tms570 Use bitfields instead of hard-coded values
Hello Joel, I have been with Premek when he tested these on the target. [PATCH 1/2] bsp/tms570: skipped 32bit field definitions and corrected single bit fields This one clean header files. There has been unnecessary defines of whole registers as fields and mistake in single bit definitions. I am not happy that this slipped, we have discused and planned use of BSP_BIT32 long time ago but we have found mistake during attempt to clean BSP a little more and get rid of hardcoded values. Patch is huge so it blocks on list moderator approval. If you do not have it received then I or Premek send it offlist gzipped. [PATCH 2/2] bsp/tms570 Use bitfields instead of hard-coded values This makes already implemented code much more readable. If these patches can make to common base it would be nice. Best wishes, Pavel ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

Seeking Projects
Hello, I am currently perusing electronics engineering (currently in final year) from BITS-Pilani University. I love embedded systems and system programming. I want to contribute to opensource community and for that I am looking for projects related to real time embedded systems. skills: C programming, Computer architecture, bash scripting, Python, basic understanding of Linux kernel. In addition I have a Raspberry PI B+ board. So project related to it will be more helpful for me to practice learn stuff. Thank you for your help and support. ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

Re: Seeking Projects
Welcome! Please have a look at our Open Projects [1] page, and you may also like to see what is being done under the GSoC [2] and SOCIS [3] programs. We have a handful of projects that are improving support for the RPi. Do you have any particular goal, or are you just looking for something to do?
