Hello everyone,

I am trying to customize my RCW, but firstly i tried to RCW which is located in NOR memory. I copy the RCW from the NOR and i put it into the SD card. I take the board RCW source to the SD card from sw3 and sw4(00100000_0) and board didn't jump to the u-boot, after all i connected to the device by using JTAG interface (from j16) however i have no idea about JTAG instructions which helps me to understand problem, by using IRSCAN and DRSCAN instructions. I scanned the almost all the documents but i cannot find those instructions. Is there anybody can tell me where are they?

Thank you for your interesting.
