are there any changes in the SPI implementation between Jessi and latest Stretch Version?
My project does not work anymore for example I'm using a Piface with SPI:
-using Jessi - >it works
-using Stretch 2017-09-07-raspbian-stretch-lite.img -it works
-using latest Stretch - >does not work
-no changes on my side so i'm wondering where to start look in to.
For me this sounds like an 'accident' in lates release?
Anyone could confirm this?
if we reduce the spi maxspeed it will work - but why
in older Raspbian we could have 125000000 as SPI maxspeed - now we Need to reduce this?
Why, this is not nice for existing applications?
