Flash download error when in deep power down mode

Benoit Chiron over 15 years ago

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

maybe you can hold the processor in reset using an external pin, release it (or not...?) and quickly erase the flash using JTAG/uv4...?
