-DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE in comand line causes error due to malformated string

[MTB]

Hello

I would like to sign an image temporarily with west CMake options as described in Enabling a bootloader chain using sysbuild using the comand line: 

-DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE=\"priv.pem\"

In it's final state I would like to specify an absolute path, where the keyfile is stored. It seems as if I am not able to provide the proper format for the path value "D:\priv.pem".

I applied this also to the example "sysbuild\with_MCUboot" and use the nrf sdk v2.7.0. The result is still a malformat for the string. 

 

PS C:\Users\User1> west build --pristine  --sysbuild  -b nrf52840dk/nrf52840 with_mcuboot  -d with_mcuboot/build -- -DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE=\"D:\priv.pem\"

setting the absolut path in the sysbuild.conf (SB_CONFIG_BOOT_SIGNATURE_KEY_FILE) compiles without error. I tried a lot of combinations but don't seem to get this to work.Also placing the priv.pm in the west topdir and using the example =\"priv.pem\" os not working.

Any idea what I am doing wrong?

Hello,

The cases you referenced look valid, and the patch suggested by one of the customers works as well. In another thread, I recommended this patch, and the customer successfully implemented it.

From reading your thread, my understanding is that you managed to get it working by specifying SB_CONFIG_BOOT_SIGNATURE_KEY_FILE with an absolute path in sysbuild.conf. The issue seems to occur only when using the command line,please correct me if I'm wrong. So I believe your issue is a bit different from what was explained in the other threads.

Additionally, when reviewing the logs you shared in the original query, I noticed a mix of both forward and backslashes in one of the generated paths.

Kind Regards,

Hi, yes your understanding is correct. However, I have the same behaviour no mattter if specifying absolute or  relative path. But yes, there seems to something else wrong.

The forward and backlashes I saw as well. Do you know what that could be?
