Lpc2000

Hi to all.
I have a board from Olimex with LPC-2103.
My first problem - I can't download program to the
board with ULINK and JTAG. I receive the message -
"Cannot load flash programming algorithm" I use
algorithm "LPC2000 IAP2 32kb Flash". If I use Philips
FLASH utility via RS232 all works fine. And JTAG
download works correct with other ARMs (STR7).

And second and bigger problem - For external
interrupt0 I write the folowing:

PINSEL1 = 0x1;//Set P0.16 to EXT Interrupt
EXTMODE |= 1;// Edge
EXTPOLAR |= 1;// Rising
VICIntSelect &= ~0x4000;
VICIntEnable = 0x4000;
VICVectCntl1 = 0x2E;
VICVectAddr1 = (unsigned long)EXT0_isr;

It should give me rising edge interrupt. But I receive
FALLING edge. It seems like EXTPOLAR register doesn't
matter. Whatever I put in it - I always receive
falling edge interrupt. Is it a bug?
Thanks.

Problems is fixed. Sorry, I found these solutions
accidentally (after 2 days stuck). 
First, with flash programming - I need to reduce JTAG
frequency to 100 kHz in Keil setup.
Second, with polarity - I need to reset interrupt
flag:

while(EXTINT & 1){
EXTINT |= 1;
}

after setup EXTMODE and EXTPOLAR
Sorry and thanks
