• Status of the integrating ADCs
  • He has tested 16 of the full delivery of the modules (all of them differential inputs so far), and found only one issue (one of the ones which had the sockets replaced). He hasn't revisited that board yet, but has been going through the rest of the boards
  • Michael will be sending a few boards to W&M, so that two can go to Bryan and William at JLab and at least one kept at W&M for detector testing
    • He'll try to get the shipment ready today, but it might be Monday
  • Michael is going to purchase a few more FPGA modules; he asked Daryl if there would be any issue with the FPGA modules, as they would have some changes, but Daryl thinks we're not sensitive to the changes
• Daryl
  • Chris spend last week getting familiar with the firmware build chain and Bryerton's notes. Daryl thinks he has everything he needs to finish the firmware work
  • Michael asks if it might be possible to flash the EMMC to be able to boot from it instead.
    • Daryl says that is the plan, but they were waiting for the firmware to be finalized.
    • Daryl says the Bryerton had tested booting from the EMMC once, but for development it is faster to work from the SD card
    • Daryl says there is a switch on the board to select what the default boot is from the SD card or from the EMMC
• Bryan
  • He's still working on getting a distribution together. He was hoping to have it ready to use with Dustin's rev1 board, but it may be after getting the rev2 board
• Chris
  • Armen has all the chassis parts.
  • Once Michael has packed the boards. we should get a corresponding number of chassis parts brought up to W&M to do the test fit, and then go ahead and package all of the boards.
• Bryan and Dustin talk about testing his rev1 board with the CODA distribution.
• Arindam has gotten the Cisco network switch back from the CC
  • Note that the Cisco switches need a high current power supply to support all of the POE ports, and have a special AC cable and plug
  • There is also a standard AC cable which is probably fine for using a small number of POE ports
  • Simona will meet with Arindam and Lawrence to figure out how to support the special AC plug in the hall and possibly also in the test lab
