4. JampII-mini Function Blocks 4.1. EP9302 JampII-mini Single Board Computer uses the Cirrus Logic EP9302 as the core processor on this development board. The top-level features of EP9302 processor are the following: · ARM920T RISC Core Processor · 200 MHz / 200 MIPS Performance · 16 Kbyte Instruction Cache · 16 Kbyte Data Cache · Linux and Windows CE enabled MMU Note: Cirrus Logic to supply either a Linux port or a Windows CE port, including the respective board support package (BSP).
The EP9302 features a unified memory address model where all memory devices are accessed over a common address and data bus. The EP9302 can support a minimum of 1 to a maximum of 4 banks of 16-bit 100 MHz SDRAM. Additionally, JampII-mini installed with 32 MB SDRAM density. 4.3. FLASH As previously stated, the EP9302 features unified memory address architecture. The EP9302 can support either NAND or NOR types of non-volatile flash memory for program code storage.

6. Development Tools 6.1. Overview This chapter provides a brief introduction to development tools that are available for the EP9302 System-on-a-Chip processor. The central processing core on the EP9302 is a 200 MHz ARM920T processor. The ARM920T RISC processing core is supported through various toolsets available from third party suppliers. The typical toolset required for the code development is a compiler, assembler, linker and a source-level code debugger.
3. Set up the directory path variable # export PATH=$PATH:/usr/local/arm/3.4/bin:/usr/local/arm/3.2.1-elf/bin The above command can be included in the shell resource file so it is executed every time you login. For bash shell, a good place to put is in .bashrc in your home directory. 6.6. Loading Redboot The following procedure will allow in-circuit programming of the flash memory via the EP9302 processor: 1) Power the board off. 2) Connect serial cross cable to UART1.

RAM: 0x00000000-0x02000000, 0x00041e68-0x01fdd000 available FLASH: 0x60000000 - 0x60800000, 64 blocks of 0x00020000 bytes each. RedBoot> A slightly different message will be displayed if the FLASH memory has been initialized and programmed before.
6.7.3 Load Root File System The default configuration of JampII-mini is using part of SDRAM as RAM disk for Linux root file system. The ramdisk image must be stored in the on-board FLASH memory and loaded by Redboot for the Linux kernel. The image must be loaded into dynamic memory before it can be stored in the on board FLASH memory.
6.8.1 Configure Redboot Configure Redboot In the ecos directory, executing the following commands, # cd ./work/cirrus-arm-linux-2.0.2/ecos-2.0/ # export ECOS_REPOSITORY=$PWD/packages # export PATH=$PATH:$PWD/tools/bin/ # mkdir redboot # cd redboot # ecosconfig new ep9302_a redboot # ecosconfig import $ECOS_REPOSITORY/hal/arm/arm9/ep93xx/v2_0/misc/redboot_ROM RAM.ecm # ecosconfig tree 6.8.
7. Application Development 7.1. Compile Application After setup the ARM Linux Development software package, you can use command Larm-linuxgccM, Larm-linux-g++M and any linux-tools for arm-machine. Test simple application by hello.c # cd ./example # arm-linux-gcc -o hello hello.c # file hello hello: ELF 32-bit LSB executable, ARM, version 1 (ARM), dynamically linked (uses shared libs), not stripped *you can check file type by command LfileM 7.2.
