Help in setting up RDP for STM32H750B_DK

[MaazSk]

I tried some tests in zephyr/tests/drivers/flash and they worked. But I was unable to use zephyr WRP or RDP protection. I want to setup a RDP (readout protection) on my stm32h750b_dk but I am unable to set the same.

I am unable to set
CONFIG_FLASH_STM32_READOUT_PROTECTION=y Even if I set I am unable to use struct flash_stm32_ex_op_rdp as it is used in the Extended operations api.

Is there a example to set Readout protection to 0xBB. I am attaching a sample code that I was trying to use it is from my earlier discussion provided by @FRASTM.
flash_h7.zip

I am getting the following error

[FRASTM]

could this be an explaination : in the drivers/flash/Kconfig.stm32, the FLASH_STM32_READOUT_PROTECTION is not settable for the stm32H7 serie.

config FLASH_STM32_READOUT_PROTECTION
	bool "Extended operation for flash readout protection control"
	depends on SOC_SERIES_STM32F4X || SOC_SERIES_STM32L4X || SOC_SERIES_STM32G4X
	select FLASH_HAS_EX_OP

There is a PR for adding the RDP to the stm32F7 serie : #76097
And I guess it probably requires one for the stm32H7 serie

Okay, I'll just check and if possible will create the PR, thank you! for the support.

Maybe as an extension of the PR for F7 : does it make sens to add the stm32H7 serie at the same time ?

[MaazSk]

I think yes, just let me know if we can do that. I am not sure how to do it as an extension but will look into that as well

[FRASTM]

I put a PR #76640 to complete the #76097

Can you please check if it answer your question ?

[MaazSk]

Sure will do that, thank you!

Hi @FRASTM,
I have not yet tested it but wanted to know when that PR will change it's state from Draft to complete?

[MaazSk]

Hi @FRASTM,
just wanted to know if we planning to merge the PR now or any other changes are also required?
Thank you!

Just want to know in which release we will have this PR merged?
Thank you!
