there is already a platform_info ROM generated by core (roottask), which would collide with this one (so only one of both would be accessible). The one option is to add this information directly to the generated platform_info in core, e.g. look for Platform::_init_additional_platform_info() in repos/base-hw. The other option is to name your platform_info differently and use the re-labeling feature of Genode's init to refer to your version of the platform_info, e.g something alike:

Hope it helps,
Thanks .. it did help for the driver ,but I am still facing memory errors:
