Hi,
Just to make things clear, what I meant was that I was wondering whether I am actually to dump the contents of the Rom FS without having to know the names of each ROM file ahead of time (which is what happens in boot up). From what I can see, when I create a rom dataspace capability, I have to specify the file that I want to access, which is not exactly what I want to do every time just in case new components are added. More specifically, I want to obtain the names of the ROM files and their addresses as part of sample processing. I also don't understand how the nested configs will help me achieve this task as well.

I noticed that as part of booting up Genode that the contents of the rom FS is printed (provided the variable is set for enabling verbose printing of boot information). Is there a way of having access to this data in my profiling environment? Having access to this information would greatly help with my system profiling.
Indeed, ROM files can be accessed via ROM sessions. Please have a look at

We kept the service as simple as possible and, therefore, do not provide readdir()-like functionality. If you need this feature, you could use the nested config support. An example can be found in the Genode sources
os/config/nested_config
