Re: bsps/xilinx-zynqmp : Add BSP for RPU

This looks exciting. As for Versal support from Xilinx's Docs "RPU The real-time processing unit (RPU) Arm Cortex-R5F processor has faster clocking frequencies than the Zynq UltraScale+ MPSoC. The Versal Arm Cortex-R5F processor supports Vector Floating-Point v3 (VFPv3) whereas the Zynq UltraS

rtemsbsd/versal_slcr: Fix Versal GEM clock set

On the Versal when the GEM clock is routed from a PLL in another domain it goes through another clock divider. This check accounts for this extra clock divider when setting the clock. Thanks, Aaron. ___ devel mailing list devel@rtems.org http://lists.r

This is great. I will carve out time to check this out on the ZU3EG and provide feedback if needed. Good job. Sent from my iPhone > On Jun 14, 2023, at 08:49, Joel Sherrill wrote: > >  > Thanks for submitting this. It has been on the wish list for a while. > > My first comment is that info

Thanks for submitting this. It has been on the wish list for a while. My first comment is that information needs to be added to the Users Guide on this BSP. Guidance on capabilities, use, and debug is always appreciated by the next user. Remember that often this is where search engines and other h

bsps/xilinx-zynqmp : Add BSP for RPU

This patch adds support for running RTEMS on the RPU (cortex R5) cores of the ZynqMP. This is only a basic BSP and does not yet support the following: - SMP - Cache - MPU Also, everything except for the startup and exception vectors runs out of DRAM, which is slow without cache. At some point in
