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?</P><P>Thank you for your interesting.</P> Mon, 24 Apr 2023 12:27:46 GMT thehk 2023-04-24T12:27:46Z https://community.nxp.com/t5/Layerscape/LS1043ARDB-board-debugging-with-JTAG-instructions/m-p/1638942#M12312 <P>Hello everyone,</P><P>I am trying to customize my RCW, but firstly i tried to RCW which is located in NOR memory.
