Implement possibility to specify options for --start and --download arguments. These options are implemented as lists to better fit STM32CubeProgrammer programming model. This options are required to enable the programming of STM32N6 in USB-DFU mode, which requires "-d my.bin 0x1 -s noack" arguments list. Signed-off-by: Erwan Gouriou <[email protected]>
Flashing in BOOT-SERIAL mode with stm32cubeprogrammer doesn't support using serial number. Signed-off-by: Erwan Gouriou <[email protected]>
When flashing STM32N6 in USB-DFU mode, as required when running test automation using twister, it is first required to power-off/power-on the board to set board ready for USB-DFU (thanks to specific BootROM configuration). Provide a script that performs this operation using STM32CubeProgrammer. This scipt could be provided in twister map.yaml file on 'pre_script' property of board entry.

This option should be used to load and run binary using "serial boot" configuration for boot ROM. Signed-off-by: Erwan Gouriou <[email protected]>
On STM32N6 based series, there is no flash available and tests are performed using load and run in RAM. From twister point of view, we should consider a flash is available with the same size as RAM. (We may tune these values later as the RAM will actually be shared between code and variables). Signed-off-by: Erwan Gouriou <[email protected]>

Twister should only be passed on the serial boot target, so remove the supported peripherals from the standard yaml file. Signed-off-by: Guillaume Gautier <[email protected]>

There was a problem hiding this comment.
This PR adds the support on STM32N6 of the following peripherals:
- DMA
- SPI
- CAN
It also enables the MPU and add test overlays for the new peripherals.This is based on top of #84869, so do not merge for now.
In the interest of having smaller, easy reviewable PRs, please split this into separate PRs. There's no reason for submitting 24 commits in vastly different areas in one PR like this.

Technically 10 of them belong to another PR so that makes "only" 14 :) |
It is not only the number of changes, but also the responsibility. We have different maintainers for each of the drivers. It is easier to see if the maintainer approved if only one subsys is touched in a PR. |
