RDI Support

High-speed BDM/JTAG Interface for RDI compatible debuggers

bdiRDI adds JTAG based debugging to RDI compatible debuggers (e.g. ADW/AXD from ARM Ltd  or EWB from IAR Systems). With the BDI1000 and BDI2000, you control and monitor the microcontroller solely through the stable on-chip debugging services. You won't waste time and target resources with a software ROM monitor, and you eliminate the cabling problems typical of ICE's. This combination runs even when the target system crashes and allows developers to continue investigating the cause of the crash. A RS232 interface with a maximum of 115 kBaud and a 10Base-T Ethernet interface is available for the host interface.
The configuration software is used to update the firmware and to configure the BDI1000/BDI2000 so it works with the RDI compatible debugger.


  • Source level debugging ARM7/9/9E, ARM11 and XScale
  • Assist in bringing up new hardware
  • Ethernet debugging also with target systems without network capability
  • Internal break register supported (allows debugging of code running out of a read only memory)
  • Fast download speed up to 340 Kbytes/s for ARM7/9TDMI and 320 Kbytes/s for XScale
  • No target communication channel (e.g. serial line) is wasted for debugging purposes
  • Easy to connect on target, eliminate the cabling problems typical of ICEs
  • Host access via RS232 (uo to 115 Kbaud) or Ethernet (10 Mbit/s)
  • 3 years hardware warranty
