llce under bsp37

[irfank]

Hello,

We have a custom board. We get the below error. Do you have any suggestions for the reason of the below error? We are using bsp37 and llce binaries under llce_1.0.6

Hi,

Have made modifications to the BSP itself? Or is it the same base a the NXP reference boards?

From our side, we cannot replicate this outcome. Since this is a custom board, help us either contacting your local NXP FAE/DFAE/representative or opening a ticket. We do apologize for the inconvenience.

Please, let us know.

Thanks for you reply, i have one more question:

The CAN transceivers on our board are TJA1145ATK/FD. We have SPI lines connecting the S32G274a and TJA1145ATK/FD to configure the TJA1145ATK/FD. we are curious if the TJA1145ATK/FD comes with default configurations or if they need to be explicitly set. 

We suspect that these errors may be related to the configuration of the TJA1145ATK/FD, 

Note : 

The function state_transition in the path tmp/work/s32g274a_n4c0a53-fsl-linux/linux-s32/5.15.96-r0/git/drivers/net/can/llce/llce_can.c return  " (msg.fw_cmd.cmd.cmd_list.get_controller_mode.controller_state == state) "

The value of msg.fw_cmd.cmd.cmd_list.get_controller_mode.controller_state  is always "LLCE_CAN_STOPPED"

    LLCE_CAN_STOPPED, : 

    /**

     * Controller is in the STOPPED state which means that it does

     * not do any bus transactions.

     */

Hi,

For TJA1145A specific questions, we recommend opening a ticket under the NXP online services, since we don't handle them directly on this community. We do apologize.

We can also recommend contacting the one who provided you with the parts. If it was directly from NXP, we can recommend contacting your local NXP representative, for them to provide more information on this regard.

Again, we apologize.

Please, let us know.
