Rockbox Player LittleObjectivesMake a simple and cheap DIY kind of prototype for be able to promote the Rockbox Player idea near to the companies that already produce and sells online electronics systems as the Olimex or Sparkfun. We are a few individuals who believes on possibility of building our own DAP from the scratch, since the hardware to the firmware. We don't own any electronics company and as that we just can build our hardware using cheap and world available electronics parts - final prototype will not look as good as any commercial device. We believe that then we can convince some electronics companies to build and sell our own player to us but with all the characteristic as any commercial device.Hardware![]() SoftwareThis section describes the RockBox port for the hardware. We are hosting our patch against Rockbox source here.BootstrapStatus -![]() Rockbox bootloaderThe Rockbox bootloader is an application that will be launched by bootstrap. The following was code was implemented: /* Initialize system */![]() system_init(); /* to initialize some peripherals. Bootstrap already did initialize the SDRAM controller, the SDRAM, etc, so not need to do much on this stage. */ /* Initialize the kernel */ ![]() kernel_init(); /* to initialize the Rockbox kernel. Kernel sleep() function is used on LCD, buttons and ATA drivers.*/ /* Initialize the LCD */ ![]() spi_init(); /* to initialize SPI bus communications. We use SPI to communicate with the LCD. */ lcd_init(); /* to initialize the LCD. */ /* Initialize the buttons */ ![]() button_init(); /* to initialize the buttons - configure the MCU IOs that connect to buttons, as digital inputs. */ /* Initialize ATA (SD card reader) and mount the FAT file system partition on SD card */ ![]() storage_init(); /* Initialize the SD card reader and the controller */ disk_mount_all(); /* Mount all partitions of SD card. */ /* Load Rockbox firmware and start it */ ![]() load_firmware(loadbuffer, _BOOTFILE, MAX_LOADSIZE); Rockbox firmwareThe firmware is loaded from the SD card by the bootloader and run it.
