Are you looking for software loopback option?
You can connect MOSI and MISO pin in hardware.
Are you referring in any other layerscape device for loop back option?
Hi @yipingwang,
Yes i am looking for software loop back option only. (I didn't find loop back enable bit in SPI control registers). I want to enable and disable loop back option whenever i want to test my SPI interface (BIST purpose).
Thanks.
