Re: Communication between SL811 and NIOS

u can see the error code in include/asm-generic/errno.h 

then in documentation/usb/error-codes.txt to see the causation of the error. 110 means timeout. 

 

by the way, 

how many setup/wait/hold cycles while you setting the sl811 scheduling as user logic???

Re: Communication between SL811 and NIOS

thanks,  

well... in the setup i have 2ns, 

in wait 65ns  

and in hold 5ns...  

 

based on the cypress application note about the interfacing with external processors... 

 

how you define your avalon slave addressing... as a memory or as a register
