Hi everyone iam new in programming ARM microcontroller i have a problem in programming STM32F407VG in assembly using keil 5 MDK the problem is concering store data in memory. my code is :
MOV R0,#5 MOV R1,#3 STR R0,[R1]
there is no error in keil but the last instruction can not change the memory in debug mode i can read from memory via LDR instruction but i can not write i think there is a problem in memory organization but i can not solve it thank you in advanse
