Uwe, thank you for issuing this. I have tried to test your patch and as I could
see the macro HAL_LPC2XXX_GET_CAN_BR() is not provided for olpce2294 target:
SYNOPSIS
ecosconfig new olpce2294
ecosconfig add can
ecosconfig tree
make -s
headers finished
... can_lpc2xxx.c:85:2: error: #error "Macro HAL_LPC2XXX_GET_CAN_BR()
missing"
... can_lpc2xxx.c: In function 'lpc2xxx_can_set_baud':
Could you, please, also define the missing macro for the target? However, I
could miss some configure options, if it so, please, tell me how you configure
and build the CAN driver for olpce2294 target?
Thank you,
Sergei

Hi Sergei,
you need to build the library with a processor clock that is supported in
can_lpc2xxx_baudrates.h. So you can try a clock of 60Mhz - this is the clock I
used for building (CYGNUM_HAL_ARM_LPC2XXX_XTAL_FREQ 15000000)

Hi Uwe,
I know this "trick" (I thought that you sent not all diff and you have more
changes under devs/can/arm/lpc2xxx). Thus, user has to replace 14.7456 MHz
oscillator on the board. I recall that such a "repairing" is not issue (the
original oscillator is set on a socket and can be replaced by new one with no
soldering). Well, if nobody has no objections I would apply your patch.
Thanks,
Sergei

Hi Sergei,
i will provide a second patch with a baudrate table for the default clock
later.

Good to know, thank you! Then I do not change the bug's status.
