flexcan_normal mode example code is not working

gomathichinnasa — Thu, 02 Jun 2016 12:08:30 GMT

Am working on CAN with k60DN512 controller, here i connected the PORTA_12 and PORTA_13 for CAN_TX and CAN_RX.

i)and i was trying to print some data through CAN, for that i took example code from this path "Freescale\Freescale_MQX_4_1\mqx\examples\can\flexcan"

then i compiled and load the code to controller but its not working properly, from that example when its enter in to Tx_Task() it is struggling "flexcan_send" this function.

ii)What i have to do for this, want to any changes in BSP file for CAN configurations,

iii) Am using the CAN0 so how to configure for this.

hi,

no am not getting any improvement on this, am not having clear idea about CAN , so help at this point.

Actually i copied the code (which is shared in the link you gave in the previous reply) and compiled and loaded to our customized k60 development board. there in the CAN0_TX and CAN0_RX pin am getting some data that is coming in every 100ms delay continuously. and also my RX_task is not working.

And also while checking the CAN register came to know some message like " An ACK error occurred since last read of this register." & "FlexCAN is transmitting a message. "and also "FlexCAN is not receiving a message." don't know where is the issue.

Thanks & Regards
