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
Yes, or your understanding of it, like flash memory mapped at zero?
Please review the part reference manual, and perhaps some materials on the Cortex-Mx cores. ARM has technical reference manuals, and this chap called Joseph Yiu has written several books on them.
The RAM is situated at 0x20000000, try writing to that.
