Hello,

I've been working on an NXP LPC1768, and this afternoon I started getting an error "Error reported by the DTC (Data Transfer Component)". The program in question is just blinking LEDs and seems to be working fine.

I'm using;
Ride7: 7.26.09.0351
RKit-ARM for Ride7: 1.24.10.0050

So I suspect that I may have inadvertantly put something in the code that is making the chip not work with the RLinkPro. I'm not sure but I don't think I'm doing anything strange to the debug port. I am however mucking around with the oscillator and power up configuration.

I was able to program the chip and at some point the RLink started giving me this error. We pulled the chip and put on a fresh LPC1768, I was able to load code into it (and the code is running). As soon as I loaded the code into the fresh chip, the RLink started giving the error, and I could no longer talk to the chip.

I'm also unable to talk to the chip using RFlasher (Pressing "Reset and Run", gives the same error message).

I have no idea what this error is, or how to resolve this problem. What is a DTC error? What causes it? How do I resolve it? Is there a JTAG script I need to set up or something?

Here's the clock config code I loaded;
#define CLOCK_SETUP 1
#define SCS_Val 0x00000020 // main OSC is 1-20Mhz, Main OSC is enabled
#define CLKSRCSEL_Val 0x00000001 // main oscillator is source
#define PLL0_SETUP 1
#define PLL0CFG_Val 0x0000000B // 2*12*8/1 = 192Mhz
//#define PLL0CFG_Val 0x00000011 // 2*18*8/1 = 288Mhz
#define PLL1_SETUP 0
#define PLL1CFG_Val 0x00000000 // not enabled... only feeds the USB interface
#define CCLKCFG_Val 0x00000001 // 192Mhz/2 = 96Mhz
//#define CCLKCFG_Val 0x00000002 // 288Mhz/3 = 96Mhz
#define USBCLKCFG_Val 0x00000000
#define PCLKSEL0_Val 0x00000040
#define PCLKSEL1_Val 0x00000000
#define PERIPHERAL_ENABLE 1 // configure peripherals
#define PCON_Val 0x0000001C // This is what is in the mbed
#define PCONP_Val 0x04A887DE // This is what is in the mbed
