xeno-test fails when kernel 64bit userland 32bit

xeno-test fails when kernel 64bit userland 32bit

[Paal Tamas]

Dear All,
I am using xenomai_3.2.1 with kernel 5.10-dovetail on x86_64 platform. I compile the kernel to 64bit, but I need to have the userspace as 32bit. So I configured the userspace compilation the following way:
./configure --with-core=cobalt --enable-smp --enable-pshared --host=i686-linux CFLAGS="-m32 -D_FILE_OFFSET_BITS=64" LDFLAGS=-m32 host_alias=i686-linux
I tried to start RTNET, but I get "Inappropriate ioctl for device" errors. I reported this issue in another thread.
The problem seems to be not RTNET realted, since xeno-test fails with the same error: desktop:/usr/xenomai/bin$ sudo ./xeno-test
Started child 2202: /bin/bash /usr/xenomai/bin/xeno-test-run-wrapper ./xeno-test
++ echo 0
++ testdir=/usr/xenomai/bin

+ start_timesyncd
+ true
+ systemctl start systemd-timesyncd
+ timesyncd_was_running=false
child 2202 returned: exited with status 1
What am I doing wrong?
Thank you,
Tamas

Nothing, known issue in principle:

There are multiple issues to be debugged and patched. Someone has to sit
down and do at least the debugging work. And we need that image for the
test lab so that the result is validated during regular runs. So far
none of those to-dos have a schedule yet.
