Dear Jan, Attach the patch on AT91 ethernet driver. Have a look.
At the line 118 in the tdma_worker.c file that you mentioned, I observed in
the trunk the function call is rtdm_task_sleep_abs but however in my
rtnet-0.9.9 version, it is rtdm_task_sleep_until. Any different on this?
I try to put the printk statement after the rtdm_task_sleep_until but I
couldn't see any related kernel messages. Is this the problem? I also put
the printk statement at beginning of do_request_cal_job but also see no
kernel log message on this. Is this because this function is not called at
all?
Please advice. Thanks
Regards,
Chun Yeow
