[Xenomai] Xenomai 2.6.4 on i.MX6 Quad

[Xenomai] Xenomai 2.6.4 on i.MX6 Quad

[Andreas Glatz]

Hi,

I recently installed the recent xenomai on an i.MX6 Quad SOC from
PHYTEC (for details see end of this Email). The base system was
created with the instructions in [1]. Then I pulled in the changes
from the ipipe 3.14 tree and installed the new kernel. It boots and I
can start the basic xeno-regression-test (see log attached). However,
at the end you can see:

RTD|           1|           0|           0
RTD|           2|           0|           0
ioctl(RTTST_RTIOC_SWTEST_
CREATE_KTASK): Cannot allocate memory
== Threads: sleeper_ufps0-0 rtk0-1 rtk0-2 rtk_fp0-3 rtk_fp0-4 rtk_fp_ufpp0-5 ...

and xeno-regression-test stops.

However, starting switchtest and latency separately on the console
doesn't produce this error. Do you have any clues what is wrong there?

Thanks.

Andreas

Just read the messages, it is written, write on black:

This issue is documented in the troubleshooting guide.

Sorry, this was too obvious :)

I increased CONFIG_XENO_OPT_SYS_HEAPSZ to 1M and now it works.

Thanks.
