PIXEL conference

• 11th PIXEL Conference
• Caribou abstact got accepted for a Poster
• Date: 18 - 22 November 2024

 

Caribou Users Meeting

• Soon a call for Users meeting will be sent
• Objectives:
  • 1 meeting / month
    • Maybe to frequent. Either specific calls or reserved slot with 2-days prior decision
  • Latest updates/releases in hardware, firmware and software
  • Feedback from users
  • From time to time, invitation directed to users to present their latest developments/results using Caribou

16:10 → 16:35 Hardware

Speakers: Eric Buschmann (Brookhaven National Laboratory (US)), Shaochun Tang (Brookhaven National Laboratory (US)), Tomas Vanat (Deutsches Elektronen-Synchrotron (DE)), Younes Otarid (CERN)

CaR board v2.0

• Still working on the test-board
• Mostly finihsed with the schematics
• No estimate for the layout

 

Follow-up on Carboard v1.4 from DESY with broken connector repaired at CERN (Tomas, Eric)

• Connector repair was successful, but board had issue with powering afterwards
• Found a broken line under an AND gate on the board. Fixed by placing additional wire. 
• Damage to line could have happened during repair (heating up of the PCB), but difficult to be sure about it
• Similar issue was once seen on a Carboard in the testbeam at CERN, which suddenly failed. Should try to find it back and see if it has the same cause.

 

 

 

16:35 → 17:00 Firmware

Speakers: Eric Buschmann (Brookhaven National Laboratory (US)), Tomas Vanat (Deutsches Elektronen-Synchrotron (DE)), Younes Otarid (CERN)

Boreal firmware:

• New Boreal architecture finalized
  • Improved versatility using modular architecture relying on Vivado Block Designs (BD), chained AXI interconnects, and packaged IPs
• New architecture tested with LED blinking firmware and Peary control:
  • Succesfull on both ZC706 and ZCU102
• Currently working on porting H2M design as pilot project for the new architecture
  • Targetting a test-beam at the end of September to test it
• A detailed presentation describing the new architecture and workflow will come very soon

17:00 → 17:25 Software - OS

Speakers: Eric Buschmann (Brookhaven National Laboratory (US)), Mathieu Benoit (Oak Ridge National Laboratory (ORNL)), Simon Spannagel (Deutsches Elektronen-Synchrotron (DE)), Younes Otarid (CERN)

Peta-Caribou

• Improved image building workflow now covers all needs for the standard Caribou system use.
  • Create, configure and build petalinux image
  • Update, build and deploy recipes (ie: EUDAQ, Peary)
  • Package and load image onto SD card, including bitfile
  • Dynamic bitfile modification now possible and uses uEnv.txt file as was done in the meta-caribou workflo

• All the workflow is easily managed by the Peta-Manager tool
  • Refer to the User Manual
• Successfull build of images for ZC706 and ZCU102
  • Remaining issue: ZCU102 MAC address seems to be overwritten during u-Boot. Currently investigating the reason. 
• Prospects:
  • Support of Mercury+ ST1 board and XU1 SoM. 
  • BSP file provided by Enclustra is only compatible with Petalinux 2022.1. Investigating how to make/get a BSP compatible with Petalinux 2023.2

 

Peary

• Clean up to prepare porting to 64bit systems
• Implementing multi-device support
