Nucleo SWD + MBED to reprogram StorM32 Controller

Description

So how can i explain how i came to the idea to reprogram the gimbal controller...
First of all i was looking into the usage and programming of bldc motors and i search for integrated brushless controller. Than i saw the Storm32 gimbal controller on e..y which is using three DRV8313 on one board. Cool! Which mcu?... ah a STM32F103. Hey i am using MBED Nucleo boards with STM Controller :-) and really there is the Nucleo board "NUCLEO-F103RB" an d it can be programed in the MBED environment! So lets cutt of the programmer of a nucleo board and use it as a external SWD programmer to hack the board.
And what can i say...yes it works fine and now i have a perfect development platform for brushless motors and this is how i have done it!

Note: This project shows not how to reproduce the gimbal functionality. So if you flash the board you FLASH the board :-) I didn't try to reflash it to the initial as-delivered condition but normally it should work

MBED Side:

Hardware

Each Nucleo Board has a programmer STLINK V2 on board.

Remove the jumpers on CN2 and connect the SWD on CN4 to the SWD of the Storm32.

I connected the Strom32 to the PC via USB therefore only GND from SWD is needed

CN4:

1: NC

2: SWCLK

3: GND

4: SWDIO

5: NC

6: NC

UART:

Close the Jumper JP4 (maybe you have to resolder it) to enable UART

Connect TX from Storm32 to RX of the programmer

Code and Pin: "Serial pc(PC_10, PC_11); "

Programmer STLINK V2 on Windows:

Install Drivers: en.stsw-link009 on Win64 bit use dpinst_amd64.exe to install

Flash Device: en.stsw-link007 --> AllPlatforms --> STLinkUpgrade.jar

Now you should be able to upload projects from MBED Online platform

Create Software and download it to the MCU:

- Now create a project in the MBED Compiler online tool.

- Bush the "RESET" and "BOOTO" button simultaneously on the StorM32

- Store it on the mounted MBED Nucleo drive

--> if you succeed a window will appear with one file in it "Details.txt"

! before storing the file bush the "RESET" and "BOOTO" button simultaneously on the StorM32, otherwise you will get a "FAIL.TXT" in the Nucleo folder.

Hi Mark. How can I use this code in Arduino? Or if there is anyone hero who can help me. Thanks

Are you sure? yes | no

some notes i gave to marc. Maybe someone finds it helpful

- if the SWD is not connected to the STORM than the fail.txt comes up.

- connect programer and STORM with SWD and both need a 5V USB plugged in into the PC (first programer is red and than the LED is turning its color/ after succe color is green)

- (i dont need this) but maybe you?? push BOOT and RESET down at the same time for 5sec

- store the mbed progam on the controller

the Storm Controller has UART. If you connect them to the programer (TX and RX) u can read out serial eg in hterm

Are you sure? yes | no

Sorry for my late reply, didnt get a notigfication....do still have the problem?

Are you sure? yes | no

Hey! Nice one. can you unplug the programmer after uploading to run the storm32 alone?

Are you sure? yes | no
