OpenOCD on LPC2103

Development Boards MicroMod

Hi,

I recently purchased LPC2103 prototype board ( http://www.sparkfun.com/commerce/produc … cts_id=668) .

When I tried to run OpenOCD on this board, the scan_chain returns 0x4f0f0f0f .

scan_chain

TapName Enabled IdCode Expected IrLen IrCap IrMask

0 lpc2103.cpu Y 0x4f0f0f0f 0x4f1f0f0f 4 0x01 0x0f

Is this IdCode correct ?. If so, why does the lpc2103.cfg ( comes with openocd ) file has the different idcode ?.

0x4F1F0F0F is the correct code for the LPC2103, AFAIK. There might be two different versions, of course; I remember Atmel changing the code for one of their AVR chips.

Is there any reason why I am getting 0x4f0f0f0f instead of 0x4f1f0f0f .

Thanks

A change in the chip is the only reason I can think of. It doesn’t look like a problem with your hardware or software. I’ll dig out an LPC2103 board of mine and see what I get.

I get 0x4F1F0F0F.
