Partial or Full chip erase before programming?

[Andrew Neil]

Keil (among others) allows the choice of whether to do a full or partial erase before programming:

Is it possible to do that in STM32CubeIDE ?

If so, how ?

Hi @Andrew Neil 

I don't think there is a nice GUI window as in Keil, I'm using the external tool configuration and depending on the argument you specify it can do either mass erase or only needed sectors:

For the sectors needed only, the argument is:
-c port=SWD mode=UR -d ${workspace_loc}\${project_name}\${config_name:${project_name}}\${project_name}.elf -v -rst

For mass erase instead:
-c port=SWD mode=UR -e all -d ${workspace_loc}\${project_name}\${config_name:${project_name}}\${project_name}.elf -v -rst

You can even skip the flash erase, or only some sectors. Everything is explained in the STM32_Programmer_CLI help.

Have a nice day,
Kraal

Thanks for that.

So is that all I need to do, or does it also need some reference to the "external tool" to be added/modified elsewhere?

[Kraal]

From the external tool configuration, the last tab "Common" there is a checkbox under "Display in favorites menu" that you should check (red box below) :

Your configurations will then show in the main menu in the IDE :

Note that you don't need to develop the drop down menu if you always use the same configuration, you can directly click on "Play_toolbox" icon (if you hover over it, the text shall say "use latest tool" or something like so).

Warning: in my case, I have to select the project I want to flash in the project pane for the tool to work OK. Otherwise it fails to convert ${workspace_loc}\${project_name}\${config_name:${project_name}}\${project_name}.elf into something meaningful and will comply.

Hello @Andrew Neil 

First let me thank you for posting.

This option is not available at this stage using STM32CubeIDE. However, plan to integrate similar feature in the tool.

(113782: this is an internal ticket number).

You mean the "Launch Group" mentioned by @Kraal ?

Is it this:

If your requirements are to specifically do this through existing options provided by the IDE - I can't help.

But CubeProgrammerCLT does give you fine control about what to erase and what to write:

CMD> STM32_Programmer_CLI.exe
Available commands for STM32 MCU:

 -e, --erase : Erase memory pages/sectors devices: 
 Not supported for STM32MP
 [all] : Erase all sectors
 [<sectorsCodes>] : Erase the specified sectors identified by sectors
 codes. ex: 0, 1, 2 to erase sectors 0, 1 and 2
 for EEPROM : ed1 & ed2 
 [<[start end]>] : Erase the specified sectors starting from
 start code to end code, ex: -e [5 10]
 -w, --write 
 -d, --download : Download the content of a file into device memory
 <file_path> : File path name to be downloaded: (bin, hex, srec, s19
 elf, stm32 or tsv file)
 [<address>] : Start address of download
 -w64 : Write a 64-bits data into device memory
 <address> : Start address of download
 <64-bit_data> : 64-bit data to be downloaded
 values should not be separated by space
 -w32 : Write a 32-bits data into device memory
 <address> : Start address of download
 <32-bit_data> : 32-bit data to be downloaded
 values should be separated by space

So with some tinkering, you could probably get what you want by that route.

 

Alternatively, the open-source flashrom project supports stlinkv3, so you could also hack a custom command into that.

 

Once you have a script/program that does what you want, you should be able to plug that into your IDE flow so that programming is done using that tool. Worst case, jerryrig a file-watcher util to launch your download script whenever it detects a change in the compiled binary, and tell your IDE not to download when you start a debug session.

At least the GNU tools have no idea. IAR toolchain seems to be smarter in interop between compiler and linker. (But I don't use it recently, as the customers migrate to "free cheese").
