The program can run normally when it is burned into RAM. In this way, the program needs to be burned in again every time the power is off, while the flash program still exists and can run normally when it is powered on again after the power is off, but the program cannot execute the relevant interface functions of the algorithm library in flash.
Hello Nigel_Zhu,
It is recommended that you check the memory mapping file of your compilation environment and link the program to the memory address corresponding to flash.
