Hi! I've checked the connections between my JTAG connector and the microprocessors and they're ok. Besides, I've run a test connection and CCS says that it has been successful. After this, I try to load the following script to the microprocessor (The same script works in my HDK using the same USB-JTAG dongle). #include "sys_common.h" #include "het.h" #include "gio.h" uint8 emacAddress[6U] = {0xFFU, 0xFFU, 0xFFU, 0xFFU, 0xFFU, 0xFFU}; uint32 emacPhyAddress = 0U; void main(void) { int temp,delay; /** -Delay Parameter */ delay = 0x100000; /* Set HET port pins to output */ gioSetDirection(hetPORT1, 0xFFFFFFFF); while(1) { /* Set HET port pin 1 high */ gioSetBit(hetPORT1, 05, 1); gioSetBit(hetPORT1, 25, 0); /** -Simple Delay */ for(temp=0;temp<delay;temp++); /* Set HET port pin 1 low */ gioSetBit(hetPORT1, 05, 0); gioSetBit(hetPORT1, 25, 1); /** -Simple Delay */ for(temp=0;temp<delay;temp++); } } /* GIO Notification function not used, but required by compiler */ voidgioNotification(intbit) { return; } I debug this script, but here CCS stops and the following errors show up: CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0 due to System Reset CortexR4: Error: (Error -2063 @ 0x0) Unable to reset device.
