  1. AT91RM9200 Software delivery

  2. Software delivery Basics Linux UBoot • Initialization and core management • Several simple peripheral drivers • Patched kernel source and binary • Ramdisk containing basic binaries and demos (http server, nano-X, ViewML…) • Uboot performs primary init of the chip • Allows to load operating systems • Cross compilers (gcc, g++) • ARM Linux libraries

  3. Basics • Basics are simple programs that run several parts of the chip • Initialization and core management • clock setting, SDRAM, MMU, interrupt configuration, core mode switching • Simple peripheral drivers and programs • Flash memory through EBI • SPI dataflash and keyboard • EEPROM through TWI • Graphic display • UHP and UDP • EMAC • USART • I2S • MCI • ROM services

  4. Linux • ATMEL’s Linux offer is made of two complementary elements • Patched kernel in two forms : source and binary • Integrated patches • Processor core, RTC, Watchdog, Serial, SPI, dataflash, I2c, USB ohci, Ethernet, Nand flash • Ramdisk that contains basic Linux binaries and demo programs • HTTP server • Nano-X • ViewML • Shared libraries

  5. CD-ROM content Documentation Software Tools • ARM920T core documentation • AT91RM9200 peripheral documentation : MPD • AT91RM9200DK external components : • video controller • RMII phy • finger chip • Serial dataflash • SMC interface • etc… • Linux application notes • Basics • Linux • Uboot • Cross-compiler and ARM libraries • Tools directory contains tftpserver and useful files for AXD
