Hi all,

I didn't found SPI loop back option in LS1046. Does it have a loop back option ? If not suggest me some other way to test its SPI.

Thanks.

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.
