Read/Write flash section using CLI

[Mkuma.7]

Hello,

I was trying to program STM32 using CLI, I want to READ/WRITE the memory flash section of STM32

I tried STM32_Programmer_CLI -c port=/dev/ttyS0 -w memory=flash readfile=HS_read.bin address=0x08000000 size=16

STM32_Programmer_CLI -c port=COM15 these commands, but it was showing the following error

Can you help me with what going wrong here?

And also can you help me with the correct STM commands?

[Javier1]

are you using an Stlink? did you tried with CubeProgrammer already?(just checking)

Hello Javier,

I am using STLINK itself, and verified with CubeProgrammer

[MM..1]

COM USB and other interfaces is designed to use with internal system bootloader, not for direct flash.

This CLI can only over stlink

"C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=SWD mode=UR -d yourbuild.elf -v -g

"C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=USB1 -d yourbuild.elf -v -g
 
here need be MCU in system or compatible bootloader mode

ofcourse many switches instead -d is possible ...

What exactly I was doing that I need to read the memory flash section and store it in a bin file?

And also How to write a specific value to STM32?

Can you help me with the proper STM32 commands?

How you connect ? This isnt arduino...

run cmd CLI without params and search your syntax, right is

-r 0X80YYYY 16 store.bin

write is more complicated, need erase etc. Based on pages and sectors.

Do what i write run only CLI without params and read showed info.

Do you know How to read FUS version using STM32 CLI?

[Remy ISSALYS]

Hello,

According to UM2237, there isn't any command to read FUS version using STM32 CLI.
