CMSIS B2B LPSPI works but is there is bug in the LPSPI RT 1160 example?
Potential bug in example code I would suggest.
I have 2 i.IMXRT 1160 boards connected via the SPI

BAD/BUGGY EXAMPLE
===========================================
evkmimxrt1160_lpspi_interrupt_b2b_transfer_master_cm7
evkmimxrt1160_lpspi_interrupt_b2b_transfer_slave_cm7
lpspi_functional_interrupt_board_2_board_master start.
This example use one board as master and the other as slave.
Master and slave use interrupt way. Slave should start first.
Please make sure you make the correct line connection. Basically, the connection is:
LPSPI_master -- LPSPI_slave
CLK -- CLK
PCS -- PCS
SOUT -- SIN
SIN -- SOUT
GND -- GND
Error occurred in LPSPI transfer !
Master received:
0 0 4 6 8 A C E 10 12 14 16 18 1A 1C 1E

End of master example!
