When running my application I still manuql an error when initializing the serial port to 2. This morning when I powered up the whole stuff, I could read the device ID but minutes later the chip didn’t respond again.

After that check for glitches and ripple on the power supply, reset XTAL pins, etc. Have you considered peeking in a startup file to see what it does? Didn’t you speed the notes on how to post source code? I’d have the Main Oscillator as my Clock Source. The frequency range of the main oscillator is 1 MHz to 20 MHz. Correct waveform shape and timing is needed to enter ISP mode. Once you program a hex file Flash Magic places the interrupt vector checksum at location 14H.

I need this constant frequenz, so i can configure my PLL. Did you put your scope on the reset and ISP entry pin? See lp2c378 thread elsewhere on this forum to catch up. Osc shows that the chip isn’t responding any more. If this becomes active some parameters will be saved into the internal flash memory and normally after that the system dies.

Message 5 of This sounds very similar to a problem I’m having with an LPC Lpcstk user manual schematic shows a trace connector, but one is not included on the board. But once programmed it’s not possible to enter ISP mode again. Using uxer site arm forums and knowledge articles most popular knowledge articles frequently asked questions how do i navigate the site.

Now I take an completely erased hardware and the ISP FlashMagic tool works fine until I use this watchdog for the first time, after that I can’t enter the boot loader mode again. Message 4 of Are you going to transfer data in both directions? Up to kb onchip flash program memory with insystem programming isp and inapplication programming iap capabilities. The nxp lpc family consists of six series of microcontrollers. There must be something that I am missing or not understanding.

That should get rid of the error that you are seeing. This is very spooky, It seems to be a difference if the system powers up or only the RESET was active with all voltages already present.

Applications Engineer National Instruments. There is no need for any!!

Sometime it was possible to communicate and program the device, but I didn’t find out what’s wrong. I’m ignoring the last 3 posts for now, as I’m trying to eliminate the error I get llc2378 initializing the serial port. Or something close to 0V?

Click on the nxp lpc cpu support package link to view the package and its contents. Hi, I have been having a similar problem with LPC processors.

LPC2378 User Manual location?

The lpc, lpc, lpc, lpc0 series are based on the cortexm3 arm processor core. Nobody is likely to be willing to help you unless you post your code using the format tags. If not then the device is not in ISP mode for some reason.

Message 6 of I haven’t come across a problem like this before. Plz go through datasheet of AT45DB dataflash.
