i am trying the sync boot option without success.

i have the mPression altera board with usb3 interface card.

i have a function iord_reg(u8 cmd) which reflect the timing diagram in AN76405.

i try to read some addresses (PP_CONFIG,PP_IDENTIFY,......)  but always receive val=0xFFFF;

i can see rdy toggles with printf.


Can you give me suggestions?

Thanks you in advance.
