LPC2468 Flash programming problem ! strange one - zanakca - Nov 5 22:51:53 2009
Hi all,
I have a .hex file generated with IAR workbench. When I download the hex file with the flashmagic tool and then reset my LCD (24x4) doesn't init, but the other functionalities of my program works just fine, (UARTs, MMC, ...).
The strange part is when I send the Go command from flashmagic, the program starts normally and my LCD is initiated and display correctly.
What is wrong here ??
Thanks for your help

Hi,
Press go command from flash magic and also check the status of p2.10 and
reset pin.

The character LCD are bit slow in voltage rise. Insert a delay before
initializing the LCD.
The LCD initialization also needs to done properly, refer manufacturer data
sheet, and have at least 50% more delay.
