Arduino for STM32

Hi ALL, my first post; the STM32 seems interesting and should ease my life as I would like to build
A RGB LED matrix and a LED cube. Before sourcing, which means great sacrifice, I need to be quite sure of what to do. I extracted the following from BROKKING´s video.


Hardware Board + FTDI USB to serial
Download and install Arduino IDE v1.8.13 ( latest )


Open IDE, Tools - 32bit ARM Cortex M3 – Install
Ater installation, close Arduino, goto Github / Roger Clark / STM32
Download ZIP file, unzip and copy Carpeta to Arduino/Hardware
ALL SET, ready to upload

Connect
FTDI 5v to STM32 5v
FTDI Rx to A9
FTDI Tx to A10
Connect USB cable to FTDI, LED should flash

If so, ready to upload sketches:

Open –Tools – Boards, select STM32F193Cc series
Variants, select 64k flash
CPU Speed, select 72 MHz
Upload Method, select Serial
Select Comm Port

Open – Files – Examples – STM32 Examples
Digital – Blink
Change PB1 to PC13

Change position of top jumper

Press RESET
Click – Upload, done

To ReUpload, press RESET again
After satisfied, return jumper and RESET. Your STM32 is READY.

Now, I have been usng a USB/UART cable to upload sketches to a standalone 328p
It´s installed with ARK MICRO driver. I doubt it uses an FT232 chip because it doesn´t have DTR,
so I use MANUAL RESET. I believe it should work, I don´t see DTR connection from USB o STM32.
I use an external 5v power supply for my 328p.
So, if I follow these instructions, using external 5v to 5v input, I shouldn´t have problems, RIGHT?
Isn´t the bootloader need? He never mentioned it. Sorry, couldn´t figure how to attach a .png file.
THANKs

And what exactly is your problem? Which step is not working?

Excuse me, Steve; THANKs for answering. Thought there wasn´t anybody out there.
I haven´t yet received my board but I´m sure I should get some confidence with it.
I´d just like somebody to assure that the tutorial IS correct,
but if something´s wrong or missing, let me know so I don´t suffer too much-

It should work.
If it doesn't then let us know.

So many posted projects... have a look-see:

Good luck. I strongly recommend the purchase of 2 boards... test both, put one aside for project and use one for code development... bad things do happen during prototyping, having 2 boards keeps you going.
