Hi All,

I was testing my SPI connection from my Master (MK22FN256) to my Flash chip (Memory Flash 4Mb(512k x 8) 85MHz ).

I have a lot of other code involved doing other things but I thought I would test my SPI code in my Main.c file (see below).

I checked my CS signal and should be asserted on Low, and was monitoring the CLK signal to determine if it start, and it didn't.  Can some advise me what I'm missing here.  My instincts are telling me I don't have a hex value to with an address available and also a hex value that I would like to send to Flash.

Can someone help?

Thanks,

Brian
