https://community.nxp.com/t5/T-Series/T1040d4-custom-board-without-CPLD-JTAG-programming-issue/m-p/1252318#M4020 Hi I have custom board designed using T1040d4 qoriq powerpc. My bareboard powerpc is currently power on using onboard power sequencing without using any CPLD. Right now i have no serial interface to monitor and debug it as both T1040 UART interfaced are attached with some other hardware over custom board. #Issue# when attached via CW usb tap its Jtag unable to program and flash bootloader via code warrior it shows " IR scan measure error" also "core not responding " in jtag log console.
