Abstract: Systems, methods, and computer programs are disclosed for providing patchable read only memory (ROM) firmware. One method comprises receiving source code to be used as input for building a read only memory (ROM) image stored on a system on chip (SoC). One or more of a plurality of ROM functions in the source code to be made patchable are identified. The source code for the one or more of the plurality of ROM functions to be made patchable is modified by generating and inserting patching code into the corresponding source code. The patching code comprises a link to a fixed location in random access memory (RAM) for calling the corresponding function.
