From 8dae933293223e28648ec72ac818ab2a98ee2482 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Thu, 17 Sep 2009 07:26:08 +0000 Subject: Add an app.lds and some stub functions for the Nano 2G - this isn't enough to make rockbox.bin compile, but it's a step towards it (more commits coming soon). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22714 a1c6a512-1295-4272-9138-f99709370657 --- firmware/target/arm/s5l8700/app.lds | 150 +++++++++++++++++++++ .../target/arm/s5l8700/ipodnano2g/audio-nano2g.c | 59 ++++++++ .../target/arm/s5l8700/ipodnano2g/power-nano2g.c | 56 ++++++++ .../arm/s5l8700/ipodnano2g/powermgmt-nano2g.c | 65 +++++++++ firmware/target/arm/s5l8700/usb-s5l8700.c | 47 +++++++ 5 files changed, 377 insertions(+) create mode 100644 firmware/target/arm/s5l8700/app.lds create mode 100644 firmware/target/arm/s5l8700/ipodnano2g/audio-nano2g.c create mode 100644 firmware/target/arm/s5l8700/ipodnano2g/power-nano2g.c create mode 100644 firmware/target/arm/s5l8700/ipodnano2g/powermgmt-nano2g.c create mode 100644 firmware/target/arm/s5l8700/usb-s5l8700.c diff --git a/firmware/target/arm/s5l8700/app.lds b/firmware/target/arm/s5l8700/app.lds new file mode 100644 index 0000000000..812bce8cbb --- /dev/null +++ b/firmware/target/arm/s5l8700/app.lds @@ -0,0 +1,150 @@ +#include "config.h" +#include "cpu.h" + +ENTRY(start) + +OUTPUT_FORMAT(elf32-littlearm) +OUTPUT_ARCH(arm) +STARTUP(target/arm/s5l8700/crt0.o) + +#define PLUGINSIZE PLUGIN_BUFFER_SIZE +#define CODECSIZE CODEC_SIZE + +#ifdef DEBUG +#define STUBOFFSET 0x10000 +#else +#define STUBOFFSET 0 +#endif + + +#define IRAMORIG 0x0 +#define DRAMORIG 0x08000000 + +/* End of the audio buffer, where the codec buffer starts */ +#define ENDAUDIOADDR (DRAMORIG + DRAMSIZE) + +#define DRAM_SIZE (MEMORYSIZE * 0x100000) + +#define DRAMSIZE (DRAM_SIZE - STUBOFFSET - PLUGINSIZE - CODECSIZE) +#define CODECORIG (ENDAUDIOADDR) +#define IRAMSIZE (0x20000) + +/* Where the codec buffer ends, and the plugin buffer starts */ +#define ENDADDR (ENDAUDIOADDR + CODECSIZE) + +MEMORY +{ + IRAM : ORIGIN = IRAMORIG, LENGTH = IRAMSIZE + DRAM : ORIGIN = DRAMORIG, LENGTH = DRAMSIZE +} + +SECTIONS +{ + loadaddress = DRAMORIG;
