Hello Andrew,
this two errors are not really CAN specific. The loopback driver overrun
test simply reads the size of the RX queue and then sends exact the
number of events that fit into the RX queue. After sending the messages,
it simply checks if the message queue is completely filled before it
sends one additional message that produces an overrun event.
I think the proiblem is that the check if the queue is completely filled
immediatelly follows the sending procedure. On the synth target this
check maybe comes faster then the RX queue could receive all events. A
small cyg_thread_delay() before the check may solve this. I cannot check
this because I do not use synth target and on my real hardware this test
does not fail.

Thanks for the test case. It has been committed.
I also added an ecosconfig import file which can be used with the
synth target. It includes the io can support and the loopback
device. It also sets the options which i think need setting. With this
setup i can run all the tests. However two of the tests fail.
can_overrun1 fails with:
FAIL:<Number of events in /dev/can0 RX queue differs from queue size> Line: 171, File: /home/lunn/eCos/anoncvs-clean/packages/devs/can/loop/current/tests/can_overrun1.c
and can_txevent fails with:
RX bufsize: 32 events in RX buffer: 0
FAIL:<Receive queue of /dev/can0 not completely filled.> Line: 181, File: /home/lunn/eCos/anoncvs-clean/packages/devs/can/loop/current/tests/can_txevent.c
EXIT:<done>
Could somebody with a better understanding of the CAN code take a look
at this. Is my configuration wrong? Is the test wrong? Is the loop back
driver broken?
Thanks
Andrew

Hi
First patch is a test of callback stuff for CAN loop driver.
And the second is a correction of data type of user parameter in
callback function. The reason is that CYG_ADDRWORD defined in cyg_type.h
instead kapi.h (as cyg_addrword_t).
Best regards
Alexey Shusharin
