APC Laboratory – CNRS / IN2P3


Board features

• CPU ARM core• Home made power supply: flexibility(1 or 2 batt, 8V to 34V), low cost• Power control system: fully configurable (‘analog’ PLD)• Slow Control (SPI devices):

– 8 DACs /12 Bits– 32 ADCs /12 Bits– 28 configurable digital I/O

• SDRAM 128 Mo• USB Key flash memory (with Linux system)• Low cost/consumption new Cyclone II FPGA : Time Tagging, FE interface/trigger, IP cores …• GPS connection (Models in study)• Telecom port (RS232, USB, ...?)


CPU Core

• ARM920T based microcontroller (80 MHz i/o / 180 MHz core)

• several interrupts• USB ports: 1(2) UHP (host) and 1 UDP • several UARTs• 4 SPI (for Slow Control and boot ROM)• Serial Synchronous Controller:

high speed serial line up to 20/40 Mb/s• Time Counters • JTAG port (In-Situ Test facility with

boundary scan)• SDRAM controller• Data Bus (32) & Address (26)• Optional Ethernet (for software

development) with an external PHY

Hardware status and schedule

Dvlpt Kit evaluated and used > 1 year Physic specification needed, e.g. event tagging, size, … Home made Power Supply :

Prototype in qualification Station controller board:

Conception doneRouting easy (serial buses, FPGA)Prototype: end 2005

use ‘south’ GPS receiver

Cyclone Firmware : in progress. Home made fake Front End board

for test: spring 2006 (south site like)

Anyhow, we are designing

and building a prototype:

missing specs replaced by

‘south’ specs.


Software Development Tools

• Cross compilation / PC Linux: gnuarm (asm, gcc, c++...)

• GDB for Linux process. (gdb on host and gdb-server on target).

• JTAG/ICE probe (BDI2000) with GDB for the kernel.

• OpenEmbedded. Tools to create a full Linux base for various embedded systems. (Use by OpenZaurus, Familiar, OpenSIMPad, OpenSlug...)

EMBEDDED (RT) Linux is the Base Line


Embedded Linux Distributionand Real Time

• Currently, we use a "Linux From Scratch" based on Busybox v1.0 ( 7Mo used ).

• Other distributions may also be used : OpenEmbedded based, Montavista, etc…

• Adeos portage done (with home made patch).Adeos is a kernel patch allowing easy intercept of IRQs and

events before (or after) the Linux kernel and, if necessary, to pass them to the kernel (Pipeline). Adeos is the core of the new RTAI version. We measured a latency between 5 and 10 us.

• RTAI : An official version for Arm920T exists, but temporarily only on one sub-architecture (EP9301).

• Possibility to use the Fast Interrupt (FIQ) “outside” the Linux Kernel.


Software StatusDrivers Available

– SPI– RTC– Ethernet/TCPIP– MTD (flash memory access).– USB (host/device ports, USB key).– Compact Flash interface.– Timers Counters (module with Adeos) has been developed and

tested: periodic tasks on IRQ of different TC. – Internal DMA (tested with SSC).– SSC (module with Adeos) : tested up to 30Mhz .– Driver for I2C (TWI) exists, must be tested.– Kernel 2.6(.12) for AT91RM9200 is in development. In test.


Software Status

• Boot– Boot on flash.

– Boot via tftp (Ethernet)

– Boot on Compact Flash Card.

– Boot on USB Key.

• Acquisition– To be Done !

– New architecture (from OS9000 to Linux)

– Comms ?


The future of the AT91RM9200

• Development around the AT91RM9200 is very active, specially with Linux. There are several commercial boards (Cogent for example), and Windows CE BSP also supports the AT91RM9200DK.

• It seems that, for embedded systems, the number of ARM processors has overtaken the number of x86 and PPC processors (source: LinuxDevice.com and WindowsForDevices.com, March 2005)

• If Auger North delayed, new (but similar) products will appear– Faster

– Lower consumption

– ….


Pending questions• Front End

– Sample Rate 100 MHz ?

– Time window ?

• GPS Receiver– Where is M12 ?

• Cant find it any longer !

– Galileo ?

• COMMS ?– Band width
