Re: Problem running RTEMS on raspberrypi3

Yes, I did try that but still, it doesn't work. I don't have any other pi's with me, maybe let's wait for someone to try it out on any older models. On Wed, Dec 18, 2019 at 2:06 AM Christian Mauderer wrote: > That handler doesn't look like an RTEMS handler. So it failed at a very > early stage.

Re: Problem running RTEMS on raspberrypi3

That handler doesn't look like an RTEMS handler. So it failed at a very early stage. Did you try a go 0x20 instead? Normally the first vector is a reset vector which jumps to the right start address. The jump can have a mode with it. So if you directly jump to 0x200080 the core might is in a w

Re: Problem running RTEMS on raspberrypi3

I tried booting it on the Pi 1 without success. So it seems that I either don't have the right steps or that something is broken. I would lean to the first one because I don't really have put much time into it. Do you have any old Pi where you could try it first? Maybe it would be good to ask whe

Re: Problem running RTEMS on raspberrypi3

What about using U-boot? I just tried running my own bare metal example using u-boot and it works fine. The 3rd stage bootloader start the u-boot and I was able to interact with it through serial. and then I used fatload mmc 0 0x8000 kernel.img ; go 0x8000 to load and run the img. I tried the same

Re: Problem running RTEMS on raspberrypi3

But I am not able to boot using the 3 stage bootloader. Can someone try booting any examples on raspi3 or other newer models? If it's work's please post the instructions. The steps that I followed are: 1. arm-rtems5-objcopy -Obinary hello.exe kernel.img 2. copied the kernel image to sd card and mod

Re: [EXTERNAL] Re: Problem running RTEMS on raspberrypi3

I'm not that sure that the right UART is used. The driver in the raspberry BSP doesn't care for the configuration file. So it most likely always uses the same UART regardless what the bootloader tells. The dtoverlay=disable-bt in the config file just adds a devicetree overlay. We currently don

Re: Problem running RTEMS on raspberrypi3

I think I have guided you to a wrong path here. I mentioned U-Boot because it is often used on a lot of evaluation boards. In the raspberry case it seems that the stage 3 loader is something different. But everything should work with that stage 3 loader. I don't think that U-Boot is necessary. On

Problem running RTEMS on raspberrypi3

I am trying to get RTEMS examples running on the RPI3, the RPI3 is similar to RPI2 so the examples built for RPI2 should technically run on the RPi3.But they don't :(, I am really sure of what is causing the problem. I followed the steps from http://alanstechnotes.blogspot.com/2013/03/running-your-
