SPARC-RTEMS5-GCC ignores or don't find libraries

Michel, Maybe I can help you out. I personally find the default RTEMS makefile to be overly complicated for simple projects. I get why its made the way it is, but ¯\_(ツ)_/¯ So the xxx-rtems5-gcc compiler doesn't have any knowledge of the actual RTEMS install. As far as I can tell, its just a f

RTEMS SPI Implementations

2019-01-30 Thread William Busacker
Hi all, Told myself that in the new year I'd finally get around to working on the Raspberry Pi's BSP some more, but before I start I have a couple questions I'd like to have answered, particularly about SPI. Not sure if this belongs in the devel list, figured users was a good place to start. I

Problems with RTEMS toolchain build 4.12 & 5 incl. Ada support

2018-11-30 Thread William Busacker
Ran into this kind of problem a while back last time I was playing with the build toolchain for Raspberry Pi. Apparently building Ada support with the RSB has been hella broken for a while. I got it working but then decided Ada was a terrible language and dropped it. Didn't want to use a languag

Since its a NASA mission, United Launch Alliance will probably let them do the webcast but ULA will likely link to it. They'll post the link on their twitter page https://twitter.com/ulalaunch If ULA does a webcast it will be on their Youtube page https://www.youtube.com/user/UnitedLaunchAllian

ARM cache usage

2018-04-27 Thread William Busacker
Hi All, Can someone point me in the direction of material that can explain how RTEMS uses the MMU on an ARM processor (specifically the ARM11 that the Raspberry Pi uses)? I want to see if there are any optimizations I make in code to take better advantage of how the memory access system works.

Angelo, As far as I know, there are very few people using RTEMS on a Raspberry Pi Zero (truly a shame to be honest). A few people here and there that I've found scattered through the mailing list archives, but a lot of their effort was put towards building the BSP foundation and not actually u

I'm having an issue with libi2c causing my program to completely halt. Basic setup it this: I have multiple tasks each running their own rate monotonic with modes all interupts, timeslicing, and preemption, with one task making calls to an SPI driver using libi2c. At times after an spi transact

Re: SPI on RTEMS RPi BSP (4.12)

2017-11-19 Thread William Busacker
No longer an issue, but replying for future reference if anyone else has the same problem. As noted in the GSoC project intro https://asuolgsoc2014.wordpress.com/2015/05/03/project-intro/ the SPI bus for the RPi still uses the libi2c api. As far as I can tell, that means the standard Linux Spi

Hello All, I am trying to get a minimum working example for using SPI on the raspberry pi, however I have been unable to get anything on the SPI ports for several weeks now. I have tried using the Linux spidev library as recommended by the user guide, however that fails to work. The function c
