Hi,
I'm am new to Xenomai and would appreciate any help / hint on solving
the following problems.
1. My switchtest fails with ioctl(RTTST_RTIOC_SWTEST_CREATE_KTASK):
Cannot allocate memory.
If increasing CONFIG_XENO_OPT_SYS_HEAPSZ is the solution what is the
recommended value ? (1024k did not work)
(FYI: Memory 8GB )
2. xeno-test fails with [something died a XXXX or ...]
3. I am compiling the kernel using [fakeroot make-kpkg --initrd
--append-to-version=-xenomaiflv kernel-image kernel-headers
--overlay-dir=$HOME/kernel-package]. After changing just the
CONFIG_XENO_OPT_SYS_HEAPSZ via [make menuconfig], when I issue the the
above command, the kernel goes on to a full recompile which takes 2
hours :(. Shouldn't it compile just the relevent parts ? (FYI i am not
using [make-kpkg clean]). Please enlighten me on this.
Thank you very much in advance.
