sbc_uja116x_s32k144 demo project LPSPI SBC_DataTransfer Error

[bjs]

Hi Community,

I tried sbc_uja116x_s32k144 by using S32DS Project from Example. When I ran the program stopped at SBC_DataTransfer function in file sbc_uja116x_driver.

/* Address of device with read only bit. */
command[1] = (uint8_t)((SBC_UJA_REG_ADDR_F(regName) | readOnlyMask) & 0xFFU);

status = LPSPI_DRV_MasterTransferBlocking(g_drvConfig.lpspiIntace, command,
readData, 2U, SBC_UJA_TIMEOUT );

if( readData[1] != command[1]) //!!!!!!!!!!! here !!!!!!!!!!!!!
{
status = SBC_COMM_ERROR;
}

I'm new to the mcu and have no clue what the cause of this error could be.  

Thanks.

The actual procedure I used is as following.

To reset the CAN transceiver to default mode connect the SBC transceiver in next configuration with the board S32K144EVB-Q100 power off:

• pin RSTN from SBC is held LOW
• CANH(J13.1) is pulled up to VBAT(J11.2)
• CANL(J13.2) is pulled down to GND(J13.4)

Power on the board with external supply 12V (J16)

Hi 

Did you follow the guide of SBC UJA116x when test sbc_uja116x_s32k144?

Thanks for the information. 

I succeeded after following the procedure described in the CAN PAL example. The board power should be off first and apply external 12 volt with those conditions.
