STM32F429AGH6, delete a loaded program

[CarlosG]

I am working with the STM32F429AGH6 card, at first I had some problems to flash it, I managed to solve it using the boot mode 'hot plug' and I loaded a program that was sure to work and everything was perfect, then I tried to load a modified program which only added a new structure, but the card when I reboot it, no longer stays on more than half a second, and does not allow me to reprogram it if it is not on, so I am looking for a way to delete the loaded program or reboot it.

Use Connect under Reset, or pull BOOT0 High, and erase / mass-erase the part.

Today I was able to solve it. To turn on the board and to be able to program it again I need to give an external power supply of 0.62 v in TP3013
