AMC13 IP Address Assignment

Changed:
<
<
The AMC13 has three PCB Tongues. Tongue 1 (T1) and Tongue 2 (T2) each has their own FPGA (Virtex6/Kintex7 for T1, Spartan6 for T2) and therefore each has their own IP address.

The AMC13 has two PCB Tongues. Tongue 1 (T1) and Tongue 2 (T2) each has their own FPGA (Virtex6/Kintex7 for T1, Spartan6 for T2) and therefore each has their own IP address.
  There are several schemes in the midst of being implemented when it comes to AMC13 IP Address assignment. The following procedures are those which I know of at the moment.
Line: 13 to 13
 
  • Final Byte for Virtex/Kintex Chip = 255 - 2*SN

2. Via MMC SPI EEPROM

In this scheme, the MMC sends a configuration packet which contains the IP address to be assigned from non-volitile EEPROM to the Spartan and Virtex chips at powerup. For information on how to load new configuration information into the SPI, see the MMC software page

3. RARP from a software daemon. This is not yet implemented (until we update our IPBus firmware) but may be come the preferred scheme.
