Re: [Xenomai] Simple application for invoking rtdm driver

Hi, Any clue on this? I guess native and alchemy skin is internally same. Then why rt_dev_xxx does not work with alchemy skin. Please let me know the alternate API to invoke rtdm driver with alchemy skin. Thanks, Pintu On Mon, Apr 2, 2018 at 7:18 PM, Pintu Kumar wrote:

Re: [Xenomai] Simple application for invoking rtdm driver

Hi, I tried changing "native" skin to "alchemy" skin and replaced header from native/timer.h to alchemy/timer.h But when I build my rtdm application, I get below error: app_test.c: In function ‘main’: app_test.c:41:7: warning: implicit declaration of function ‘rt_dev_open’

Hi, Thank you so much for all your explanation. But, before I dig deeper, I have some simple questions which is troubling me. 1) In Idle case, we see latency improvement (~2-3 micro-seconds on average) using Xenomai native task application, compared to normal posix thread application (with 100

Dear Philippe, Thank you so much for your detailed explanation. First to cross-check, I also tried on ARM BeagleBone (White) with 256MB RAM, Single core These are the values I got. === NORMAL KERNEL Driver Build (with xenomai present)

[Xenomai] Simple application for invoking rtdm driver

Hi, I have developed a simple rtdm driver using: open, read_rt, write_rt, close. Now I wanted to test it using a Xenomai native application, using native skin. Here are my observation. 1) If I use normal open, read, write system call, then Xenomai reports that normal read/write method is used
