Add example for remoteproc #2

Closed dinuxbg closed 9 years ago

dinuxbg commented 9 years ago

Try to write a pru-gcc example for the new PRU bridge, or write a simple standalone rpmsg example. This will probably require some trivial changes to the remoteproc driver in order to load the pru-gcc ELF variant.

dinuxbg commented 9 years ago

Remoteproc kernel driver must mask the IRAM address for PRU binutils ELF images to be loaded. See attached patch. 0001-Fix-remoteproc-to-work-with-the-PRU-GNU-Binutils-por.txt

Can you send a pull request for the patch?

jadonk commented 9 years ago

Oh, wait, I thought this was against the TI examples. Nevermind. Thanks again for advancing this project!! We need to try to get this into RobertCNelson's package feeds.

Added example and step-by-step instructions with commit 825ee2f5d84e1675bd9e51420c81eebcea992be5

Thanks Jason. I created a pull request here: https://github.com/beagleboard/linux/pull/47 . I hope this is the correct github project.

RobertCNelson commented 9 years ago

Thanks @dinuxbg all merged up in v4.1.x/v4.1.x-rt branches... I just pushed a build a couple hours ago for dsp/c6000 support on the x15, so the worst case this will get tagged/pushed as r24 next thursday..

dinuxbg commented 9 years ago

Thank you for merging the fix. I'll make sure to use the correct github project next time.

@dinuxbg that one is perfectly fine and the reason it's their for users/developers. I then 'git am' the patch into a overly complex build/merge/patch script system. (things are based on two moving targets, ti.com/git/ and kernel.org stable's tree..) Regards,
