I am using an LPC2214 and trying to run from the flash. The only way I can program the chip is through the Keil Ulink connector. I use the LPC2000 256k flash programming algorithm provided with the SW. When I program the flash, nothing runs. When I enter the debugger, it is stuck in a loop inside of the boot loading code in the 0x7ffff252 range. For some reason it is looping until it sees a one on the Rx0 line. Does anyone know why it is doing this? Can you change the boot code by using the JTAG connector provided? Thanks
Thanks for the help. I had to break out the voltmeter for this one. Our systems guy thought the pin had an internal pull up like the tace,debug and boot0 and boot1 pins, but it does not. Luckily he attached a jumper to the pin so i can force a high on it. Thanks for the help.
