Provide error details in McuBoot.receive_sb_file

[robin-nitrokey]

Currently, McuBoot.receive_sb_file returns a boolean indicating the operation result. It would be useful to access more details about the error if the operation fails.

Hi, in case of a failure you can refer to McuBoot.status_code property for more details. You may get a stringified error message for the status_code using spsdk.mboot.StatusCode.desc(status_code)
In the next release, we plan to add a new property "status_string" that will return a status string message directly.

Another way is to use McuBoot with cmd_exception=True. With this setting McuBoot will throw an exception based on spsdk.SPSDKError in case of an error.

I somehow missed that, thanks for the pointers!
