If that kernel version supports the Altera FPGA manager you might be lucky, else not so much I do not think you will find much support from here for that setup but maybe you can explain a bit what you are actually trying to do: if you use an EtherCAT master to talk to _remote_ EtherCAT devices, what is the purpose of talking to _local_ devices connected to the FPGA? -m ps: below it should say "The BB uses Xenomai2 on a 3.8 kernel base ..." > > 在 2016年8月24日星期三 UTC+8下午8:22:11,Michael Haberler写道: > > > Am 24.08.2016 um 14:05 schrieb lf <[email protected]>: > > > > Hello Michael: > > This is my mistake.Your image is ok,I have tried again.It can be written > > to SD card. > > There is a question I want to ask you.The kernels for all platforms are > > based on RT-PREEMPT kernels and that is to say Xenomai kernels are no > > longer supported? > > That is factually wrong.
