some days ago i got access to a rockchip player including the RK260x chip. i took a look on it and found a way to extract the first 0x200 bytes of the first block inside the RFW firmware file (you don't need any informations by the manufacturer to do this, just investigate their protocol and you know how to do it). anyway, i still have problems to understand the RFW file format. against s1mp3 players format, these files don't contain any text strings which would simplify analysis a lot. i investigated the file header and found several entries which point to different blocks inside the file. i also recognized one of these block is the ressource file (e.g. similar to UI30.RES on s1mp3 devices), while others contain program code of the firmware. if anybody can give me more detailed information about the RFW file header and structure, i guess i will be able to write a firmware extractor for the RK260x series. btw. which machine code get's used for the controller, are there any disassemblers?
