Re: Acessing PL devices of Xilinx Zedboard

elease version of RTEMS 5.0. But hopefully this points you in the right direction. In particular, I know that some work has been done to support 4kB pages, but I don't know if the entry point arm_cp15_start_setup_translation_table_and_enable_mmu_and_cache currently uses that s

libquadmath or mpfr support

In our project we have a use case that justifies using double-double arithmetic. Is it possible to get the RTEMS toolchain to include libquadmath.a in the build? Alternatively, does anyone have experience getting mpfr installed and running under RTEMS? Thanks, -- Jonathan Brandmeyer PlanetiQ

Using the EDF scheduler

notonic tasks? If I restrict rate-monotonic tasks to just one core with the affinity API, then it sounds like the other core will always be free to schedule event-triggered tasks + the remainder of the rate-monotonic core. What other tools are available for this purpose? Thanks, -- Jonathan Brand

Prerequisites for chdir at Init() time.

s to have the right side-effects on creat() and open() calls. What's up with that? Is it intentional? Or is the shell's chroot() covering up some deficiency in the way that the `rtems_global_user_env` is getting initialized when the IMFS rootfs is set up? Thanks, -- Jonathan Brandme
