Hi, I'm testing SPI in flexio in s32k148 eval board. I have tested the initialization part (SPI Master configuration).
Can i do the loopback test without connecting the slave device to eval board to ensure my driver is working properly ??
or is there any other way to ensure that the transfer function is working? (I don't have scope/logic analyzer as of now)
Please help me.....
As Daniel pointed out it is enough to connect MISO to MOSI. Just to add something of help maybe, of good use would be an oscilloscope that can decode SPI or better off a logic analyzer to be sure your board does what you expect it to do.
