No. I mean the EXTINT.1, EXTINT.2, and VPBDIV.1
workarounds which in fact don't always work.

The external interrupts are broken. However
certain specific configurations do work. Search
the list. This has been discussed some weeks ago.

Hey Gilles Faurie,
i checked the Errata sheet and build in the workaround.
Ive modified my Code to this:
void init_interrupts(void){
SCB_MEMMAP = 1; //interrupt vectors reside in flash
toggle_led(28);toggle_led(28);toggle_led(28); // Function Start -
Blink 3 times
VICProtection = 0; //No Protection
VICIntEnClear = 0xffffffff; //Clear all Interrupts
EnableIRQ comes from the armVIC.h , which is in the example dir of
WinARM.
My problem is, that the System hangs now on the execution of
"enableIRQ()".
Could it be, that there are some Problems with my Startup Code ?
I use the Startupcode from the UART Example included in WinARM.

Hello,
For a LPC 2294 i had a problem with EINT2. When i was configurating EXTMODE
(EXTINT in your example) register my program was hanging.
I found solution in errata sheet. There is a problem with EINT2 and VPBDIV.
to program EXTMODE you must follow this procedure :
sauve_VPBDIV = VPBDIV;
VPBDIV = 0;
EXTMODE = 4;
VPBDIV = 4;
VPBDIV = sauve_VPBDIV;
Perhaps you have the same problem on LPC2124 see erra sheet of philipps.

Hello everyone,
ive got a problem with the configuration of the external interrupt
EINT2(P0.15). The controller hangs up after
"VICIntEnable = (1<<VIC_EINT2); // Enable EINT2".
Here is the pinselect:
PCB_PINSEL0 = (1<<0)|(1<<2)|(1<<31); //UART0 TXD/RXD ,EINT2 on
P0.15
And the define for VIC_EINT2:
#define VIC_EINT2 16
I cant recognize any toggles of the LED.
Thanks for your efforts.
