How to startup communication from S32k148 MCU to SBC in S32k148evb board q176pin?

[young_man]

NXP was said in order to startup the communication in UJA1132 with SPI,we must remove thw R177 and R154 .So how do this used to jumper lines?

Hi@young_man

Can you tell me where you got this from, I need to check if this information is correct

[young_man]

I bought a board of S32K148EVB-Q176 .

The board SCH is S32K148EVB-SCH-29644-RB and another question is SBC type is UJA1131F5v0 on board ,but one is UJA1132F5v0 in S32K148EVB-SCH-29644-RB.

And set SPI  communication from MCU to SBC with read UJA113X_SER,the pdf said  ''During a write operation, the UJA113x monitors the number of SPI bits transmitted. If the
number recorded is not 16, 24 or 32, the write operation is aborted and an SPI failure
interrupt is generated (SPIFI = 1), if enabled (SPIFIE = 1). '',that means frame buffer must be 16bits transmission or buffer is 8bits frist frame and need second 8bits frame to startup SBC(1131/2).

Hi,

I don't quiet understand your question,if you want to communicate with SBC,you can take a look the demo provided in S32 DS,I attached it for your reference.
