memory allocation while using a GUI to alter this change or technically programmi

Ok, Here is the situation as follows.

You know where you are required to program your MCU. Technically speaking, having the following memory locations:

0x20003200

0x20003202

.

.

.

and you need to assign the following characters to each memory locations.

0x20003200 ==> '|'

0x20003400 ==> 'f'

.

.

.

and you can easily use IAR or other IDEs to program it and get what you want.

However, I am not willing to use any IDEs to program this specific parts of the memory?

Having said that, I am not going to completely refrain from using the IDE. I would like to flash it and then rewrite the memory with an external source to meet my need.

Therefore, I would like to make a GUI to detect the micro type that I have on my board firstly, then picks the characters of my choice and write it into my MCU.

What tools should I use? What is most important thing that I should care of?

These are the questions that I need to cope with.

To give you a better picture of this here is should be ended up with.

Choose your characters: [=,t,:,|,@,♯]

Choose the memory locations: [0x20003200, 0x20003202, 0x20003204, 0x20003206, 0x20003208, 0x20003210]

Thank you in advance!

p.s. And please don't advise me to get Elprotronic in order to do this! With all do respect! :)

The System Loader in ROM also permits connectivity via USART1, and provides a protocol to read/write memory. There are also MCU DBG DEVID registers which can be used to identify the STM32, Core, along with ROM based constants for RAM and FLASH.
