I tried to run a WebServer example from Keil on my non-Keil LPC2378 board. Since then, I am receiving Could not stop ARM device error when I try to program it with ULINK. I read in some other thread, that I should use ISP programming software, but even the bootloader isn't responding and I am receiving timeout errors. Is there anything I can do?
I tried anything, even with 5kHz, but it didn't work. I tried pressing the RST button on my board together with pressing the load button in uVision and after a few tries, it even worked! But I am afraid to use this sample again, not knowing if I will be able to do this again.
I have the same problem. After reducing the JTAG clock to 100 kHz I managed to download code to the flash of my LPC2378 on a Keil MCB2300 board ONCE. After that I get the error message "No JTAG devices found", regardless the JTAG clock speed. What has gone wrong?
Hi mark,
Are you using latest uV download 3.04 ?
Also Is your UART0 connected to PC serial port? If so did you disabled the USRT0 reset jumper on the board ?

Using the newest FlashMagic version (http://www.flashmagictool.com/) it is now possible to recover LPC23xx devices that have been incorrectly configured.

Thanks for your replies. I have downloaded the newest FlashMagic and followed the instructions from the link www.keil.com/.../mcb2300_fp_flash_alone.htm. I have checked my jumper settings, but still no luck. Any more ideas?
Thanks, Marc
