Hi, I'm using Keil (UV3) with the Olimex LPC-H2294 board and I just can't get any of my programs to work. I made a very small program to turn on a led in the board using the Keil suplied Philips startup ASM file and just 2 lines of C code to setup the IO0DIR and to clear the desired pin. The program complies fine and the HEX file looks Ok (as far as I can tell) , I use the Philips LPC2000 Flash Utility V2.2.0 to upload the file and it works ok, but when I do a "Compare Flash" the Philips LPC2000 Flash Utility tells that the "file compare failed" and the program does not run on the board. I have upload to the board (using the Philips LPC2000 Flash Utility ) the HEX file with the exemple program suplied by Olimex and I DONT get "file compare failed" and the board works fine. So, the board is in perfect working condition. Can someone please give me some sugestion on what is going wrong , is there any special issue with Keil and the ? Thanks Paulo A. |

Once or, maybe, even more in this forum was mentioned, that the Philips Flash Utility has a bug, it does download, but do not work with "Compare Flash" function. Buy the way, V2.2.1 is now available, but again the bug is not corrected, though, if Philips open its source code, any programmer can easily correct this bug.

Hi Varuzhan, Thanks for your reply. The strange thing is that the Philips Flash Utility works fine when doing a "Compare Flash" with the Olimex suplied example HEX file. Ok, ignoring the "Compare Flash" error with my program I still dont understand why a stupid simple program like this: #include <LPC22xx.H> int main (void) { // define P0.30 as output IODIR0 = 0x40000000; // bring P0.30 low (led is conect betwen VCC and P0.30) IOCLR0 = 0x40000000; while (1); } which uses the Keil suplied startup ASM file for the Philips LPC22xx does not work. Any ideas ?

Paulo P0.30 defaults to AIN3 at powerup. You need to set its usage to GPIO in PINSEL1 before using it.

Bill, Stupid me, I skipped that part in the datasheet :( Everything is OK now and my program is up and running :) Thanks to you and to Varuzhan.
