Hi, I have a Mini54zde chip in an application. I programmed it and everything was well quite a few times. Recently I uploaded a code revision and I think I boot looped the core. It starts and reboots almost immediately causing keil to display no target connected or internal command error.
How can I halt CPU execution immediately at start so that I can flash new code.
Doesn't sound very Keil.
I guess you'll need to figure out how to select the boot rom modes, IAP/ISP, etc. Look at what tools Nuvoton offers.
Would suggest you put a trap-door in your code in the future so you can sense a GPIO state early in the reset process and go into a safe mode.
