====== CUPID µTCA Settings ======


**CUPID = Control Unit for Profile and Image Data**

The microTCA based DAQ for this type of measurements consists of:

  * Native R2 6 Slot MTCA.4 chassis
  * CCT AM G64 Xeon CPU
  * Vadatech AMC217 GbE switch
  * Nat-Phys-80 MCH
 
To optimize the setup following configuration settings were applied:

on Vadatech AMC217:
  * connect via local LAN (192.168.40.230) on web browser e.g. with old Linux laptop with IP 192.168.40.200, Gateway 255.255.255.0 and DNS 192.168.40.1 
  * disable spanning tree
  * disable Port 1 on mTCA backplane

on NAT MCH:
  * provide web access via console (DHCP on)
  * via web access disable port 1 and activate Port VLAN
  * disable in Port VLAN all connections from AMC1-6 to FRT1 and CPU1
  * enable only link between FRT1 and CPU1 and UPDB and CPU1.
  * A working config can be loaded {{ :projects:cupid:nat_mch_running_cfg.txt |here}}.

====== MCH Hub Module AVR Update ======

Please check on MCH web access under Board Information, Hub Module Information, the Microcontroller Version number. It should be V1.8 or higher.
There has been a bug with V1.7 which led to complete PCIe Links loss after setting VLAN parameter, e.g. by loading the nat_mch_running_cfg.txt file. 
To update the AVR for the Hub Module use:

Update via Web access: {{ :projects:cupid:mch_pcie_webupdate.tar |V1.8}}
Use the MCH web access, there Update MCH. Upload the tar ball.


Update via script: 

The hex file for V1.8 is offered at fsl00c tftp server under /lobi/firmware/mch_pcie_x80_avr_pcb1_2_v1_8.hex
An example script also can be found in the same folder via asl740:/common/tftp/lobi/firmware which needs to be edited before usage.
The script requires telnet access without pw to the MCH.

Update manually via CLI on MCH:

Have the {{ :projects:cupid:mch_pcie_x80_avr_pcb1_2_v1_8.hex |hex}} file.
Go to MCH command line interface (CLI) and enter diag.
The select 11, 2, 3.
Enter 140.181.134.236:/lobi/firmware/mch_pcie_x80_avr_pcb1_2_v1_8.hex

Reboot MCH. Check new Firmware version under web access/ board information /Hub module information
