facing problem while executing the "flexio_spi_master_edma_lpspi_slave" examp

Hi All,

I started working on SPI drivers and its SDK driver Example codes (MIMRTX1170) "flexio_spi_master_edma_lpspi_slave.c"

did the connection as per the "Readme.txt" file

To make the example work, connections needed to be as follows:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SLAVE connect to MASTER
Pin Name Board Location Pin Name Board Location
SOUT J10-10 SIN J26-6
SIN J10-8 SOUT J26-4
SCK J10-12 SCK J26-2
PCS0 J10-6 PCS0 J26-8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

not sure on this

Board settings
==============
Remove 0Ω resistor to R406,R408,R404.

current execution is stopped here.

/* Wait slave received all data. */
while (!(isSlaveTransferCompleted && isMasterTransferCompleted))

attaching snap for the same.

any other board setup is required ?

later I tried different example SPI Driver example ("flexio_spi_int_lpspi_transfer_master") it worked !

some issue with EDMA example code

Thanks

Sathish

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) any other board setup is required?
-- Yes, another board is the slave and it runs the flexio_spi_int_lpspi_transfer_slave demo code.
Hope this is clear.
Have a great day,
TIC

@jeremyzhou i understand that we need two boards for b2b examples
