not driver found in can bus samples for olimexino_stm32

[boonpin1975]

is the canbus supported for olimexino_stm32 ?
reproduce :
west build -b olimexino_stm32 samples/drivers/CAN
console output :
uart:~$ �*** Booting Zephyr OS build zephyr-v2.1.0-1628-gb45b1e393c95 ***
CAN: Device driver not found.

I don't have hardware to test but CAN support on olimexino_stm32 is enabled since 2302d26.

Maybe @alexanderwachter you can comment on this ?

[alexanderwachter]

@boonpin1975 Can you turn on the debug log-level for the CAN driver and send the logs?

[alexanderwachter]

@boonpin1975 don't forget to connect the board to a CANbus that is terminated.
Otherwise, the driver does not initialize, because it needs 11 recessive bits on the bus to initialize.

hi all ,

I am connecting the olimexino_stm32 to the komodo can solo for verification purposes , CANH -> CAN+ ( komodo ) , CANL - > CAN- (komodo) , GND -> GND ( komodo )

there is no can log in the uart console , can you please clarify ?

Are you on the latest master?

I just built it and the labels seem to be generated correctly. Unfortunately, I don't have a board to test.

[boonpin1975]

the version is 2.1.99 . I can build the example but it can not loaded the CAN driver when connected to komodo can analyzer
=== status of zephyr (zephyr):
On branch master
Your branch is up to date with 'origin/master'.

[alexanderwachter]

@walzert can you check if the tip of master works on your setup?

[walzert]

@alexanderwachter will do that tomorrow.

[alexanderwachter]

@boonpin1975 did you get your board working?

[alexanderwachter]

No response from issuer since two weeks.

I have same problem，I open the can Log，and it's seems because it's doesn't get 11 recessive bits on the bus to leave sleep mode
