Arduino for STM32

is it possible to reset the board (or mcu) by code, instead of pressing the connected pin "reset" button?

at this moment I think I have solved the problem. Monday I'll check.
I solved the problem by turning on the board by holding down the UT button, which allowed STM32cube programmer to connect to the board via STLINK, after which I reinstalled the "mini_maple_boot.bin" booloader.

now i tried with STEM32Cube programmer and with connection STLINk the error is the same.
with UART give me this error:

Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...

the connections are OK.

until yesterday, using arduino ide with bluepill f103cb, i had uploaded regularly. today after some changes to the code, when I upload it gives me the following error:

Sketch uses 32960 bytes (25%) of program storage space. Maximum is 131072 bytes.
Global variables use 1304 bytes (6%) of dynamic ...

I have a doubt regarding the physical positioning of the adxl345 and hmc5883L break boards.
By physical location, I mean putting the card with the sensor on a horizontal plane, or I can mount it vertically.
Is it enough to swap the values of the x, y, and z axes in relation to what is printed on the ...

Ok. I reset everything with stm32cubeprogrammer.
Now everything works, but I'm struggling with another kind of problem due to the mcufriend_kvb library, which I'm checking out.
anyway thank you.

the card and the pin are those included in the previous link

I'm on my first and a half project with STM32. the first I tried to do it with "blue pill" with 64k, but unfortunately I ran out of memory resources, and then I switched to using the mini marple with 128k.
With the blue pill everything was fine for the upload, but with the mini maple the problems ...

I am a retiree, and I studied electronics (40 years ago) and now that I have free time, I am dedicating myself to building projects using STM32 and programming simple web pages.
I joined the forum hoping to have some help on my current project, (which was too big for arduino), related to an ...
