ok i'm sorry i wasn't clear at all...
my problem is : when i call readl in a rt_task, the task is stopped...
(maybe because the rt_task is launched in a module?)
"Xenomai: suspending kernel thread bf0041c8 ('test_rt') at 0xbf003824 after
exception #0"
if i remove the readl there is no problemWith a normal Linux, in a module there isn't any problem thanks 2011/4/22 Gilles Chanteperdrix <[email protected]> > Aurele Traynard wrote: > > hello, > > > > I am new in xenomai, I am trying to make a module to read a "FPGA > register" > > who is on the "data bus". > > without xenomai I use "ioremap" and "readl/writel" but with xenomai those > > doesn't work... > > > > so i would like to know how i could read this register? > > i would like to know if there is a book i could read? > > > Ok.
