John Hi, Thank you for coming back on this.
I'm trying to connect 2 SPI busses on the BBB (HDMI disabled) and configure SPI1 as SPI slave so that I can sent messages from SPI0 to SPI1 - this allows me my application development and laterone I'll connect the respective SPI slave and master devices Thank you Yaron On Wed, Mar 23, 2016 at 10:37 PM, John Syne <[email protected]> wrote: > What exactly are you trying to do?
