I accidentally programmed all flash to 0 (but did not enable flash read protection), and then the chip debug function encountered an exception; I want to know what happens to the chip if Flash is programmed to 0.
Thanks!
Hello @Lu888
How about programming a simple example?
If still can't work, please enter ISP mode, using Flash Magic erase all. Then try again.
"A LOW level after reset at the PIO0_1 pin is considered as an external hardware request to start the ISP command handler either via UART, if present."
