I am testing the UJA1169TK/F/3Z and my MCU is S32K146（64 pins）.
The 1169 is configured in Forced Normal mode in the factory. Therefore, I can now use the CAN communication even if I do not configure 1169. These have been debugged and passed on my board.
But when I use flexio_SPI to read the status of 1169, the return is always 0.
I know that in the SDK "sbc_uja116x_driver.c" use LPSPI by default, but I can only use the flexio SPI on my board.
So, I made some changes based on the SDK.
My expert component is configured as follows：
MOSI : flexio 5 = PTE 11
MISO : flexio 4 = PTE 10
CS : flexio 6 = PTE 4
SCK : flexio 7 = PTE 5
Some related code in my project：
status = FLEXIO_DRV_InitDevice(INST_FLEXIO_SPI1, &flexIODeviceState);
status = FLEXIO_SPI_DRV_MasterInit(INST_FLEXIO_SPI1, &flexio_spi1_MasterConfig0, &flexIOSPIState_Master);
status = SBC_DataTransfer(SBC_UJA_IDENTIF, NULL, ®Data);
In the "SBC_DataTransfer()", I replace the "LPSPI_DRV_MasterTransferBlocking()" with "FLEXIO_SPI_DRV_MasterTransferBlocking()"
Below is the debug result:
From the datasheet, these registers should be readable：
Although the read returns are successful, the results are all zero.
