Yes indeed it is. I got error and after a while figured out a write to configuration register from master need to be acknowledge in status register from slave via SPI, there also was a problem with SPI fifo causing read of old values with big confusion. I have some error in sync manager configuration but that I will figure out and with check for this disabled it enter operational state!
I have not yet fully figured out the purpose of sync manager and FMMU. Neither about the configuration procedure. It's my first try and sooner or later I will figure out. > Wow... that's great! > > Dave > > On 12/24/2017 6:44 AM, Nicklas Karlsson wrote: > > I just got SPI started on my Ethercat LAN9252 board.
