I have programmed an LPC1768 to be nearly always in deep power down mode. It is waken periodically by an RTC alarm
Since I did this, I cannot reprogram the processor using the programmer included in Keil's microcontroller development tool kit.
What is the solution ?
Best regards
Some more information : programmer/debugger's name is U-LINK ME
Error message is : "Error: Flash download failed - Target DLL has been cancelled"
The processor runs its program normally from what can be seen with an oscilloscope.
maybe you can hold the processor in reset using an external pin, release it (or not...?) and quickly erase the flash using JTAG/uv4...?
Thanks, but, it does not work
