I am trying to setup CAN communication between S32G and S32K344 devices.
I am using
Goldbox with s32g274a
GoldVIP v 1.3.0 using linux bsp binaries
I want to use FlexCAN0 port on S32G for Tx and Rx
On S32K344 I am using RTD 2.0.0 and CanTRCV 0.8.0 packages
I am using CANFD with controller baud rate 500 Kbps and CANFD data baud rate 2000 Kbps in polling mode.
I have tested the S32K3 SW stack to communicate between 2 nodes of my S32K3 board which tells me that setup on S32K3 is ready to tx and rx messages.
Communication setup :: Tx and Rx between FlexCAN0 (S32G) <---> FlexCan0 (S32K3)
I have found a file in GoldVip sw named canperf.sh in cangw directory which contains the commands to trigger a tx and rx on s32G. default communication in example sets up a commuication between can0 and can1 of the s32G.
command example: ./canperf.sh -t can0 -r can1 -i 0 -o 4 -s 64 -g 0 -l 10
Questions:
1.) How do I define a Tx and Tx node of S32K3 in above command on the options -t, -r , -i,-o
for example: if I am Txing from S32K3 and Rxing on S32G can0
then I can set
-t ?? (what would be name of an external node Txing the message)
-r can0 // want to receive data on s32G CAN0
-i 16 // indicate the id of Tx on s32G . Its same for Rx message from s32k3
-o 17 // to indicate the id of Rx messages on s32G . its same for Tx from S32k3
2.) How do I run a preconfigured command sequence/script (like a c code) in the s32G which contains the code and configuration to transmit data to s32K3 and receive data from s32K continuously without need of issuing commands and run after boot .
