Need help with CubeProgrammer CLI syntax

[NArnd]

Hello,

STM32L4+, CubeProgrammer 2.21, ST-Link V2, Windows 10

I need to do:

* Full flash erase

* Write Application image (.hex or .bin)

* Write Bootloader image (.hex or .bin)

* Set RDP level 1

* Start the application at the Bootloader start address.

-

I am successfully doing this with the CubeProgrammer GUI, but I fail to get it to work with CLI.

The "-e all" command works and says "Mass erase successfully achieved":

C:\"Program Files"\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -c port=SWD ap=0 -e all

-

However, I have tried numerous variants of the following command (and its separate parts alone) without success:

C:\"Program Files"\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -c port=SWD freq=3900 ap=0 -e all -w C:\SVN\Path\More_path\hex\Application.elf -w C:\SVN\Path\More_path\hex\Bootloader.hex -ob rdp=0xBB -s 0x08000000

I have also tried with .bin files and their respective start addresses.

The only response I get is the header:

-------------------------------------------------------------------
STM32CubeProgrammer v2.21.0
-------------------------------------------------------------------

-

The command "-c port=SWD freq=3900 ap=0 -s 0x08000000" gives a complete (failure) response:

-------------------------------------------------------------------
STM32CubeProgrammer v2.21.0

I have tried to find a tutorial or a list of CLI command examples but um2237 is a wee bit brief and I haven't found much on the internet.

Grateful for your input.

It's not possible to do the last step. You can't run flash in RDP 1 in debug mode. The chip needs to boot up normally.

Thank you TDK,

So, I need to do:

> * Full flash erase

> * Write Application image (.hex or .bin)

> * Write Bootloader image (.hex or bin)

> * Start the application at the Bootloader start address.

This works in the STM32CubeProgrammer 2.21.0 GUI. (And setting RDP to level 1 as an individual step.)

The log from the GUI using JLINK (omitting the RDP change) is:

It should be mentioned that both when using ST-Link V2 and JLINK Ultra+, I now sometimes need to do the above procedure twice to get it to actually succeed with "Run after programming".

I've continued testing various approaches with CLI without success:

* CubeProgrammer 2.17.0, 2.20.0, and 2.21.0 with ST-Link v2 (latest FW)

* .elf (with and without address) and .bin, .hex, and .srec with address

* Segger JLINK ULTRA+ (latest FW)

* Files generated by CubeIDE 2.0.0 in both debug config (debug level 3, no optimization) and release (no debug info, optimization for size)

The common behaviour is that the commands that don't involve -w seem to be accepted and processed.

Just issuing

C:\"Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe"

doesn't respond at all (although some internet sources claim that this should respond with a list of possible actions).
