About the development of ST's 8032 core microcontroller uPSD3234A-40u [Copy link]

Regarding the development of uPSd3234 chip, I use an 80pin chip with external memory interface, and it also has main Flash and secondary Flash inside. I use Keil to develop. I configure P1 and P3 according to the 51 program, and download it to the secondary Flash of the chip, but the program does not run! ! !
How to set the startup mode of this chip? Does it run the program from the external memory by default? How to change it to run from the secondary flash? How to configure it?

This should be explained in the device manual.
