MCE firmware

Critical Notes

• In v5+ firmware, if you update firmware on any readout card, the card doesn't reply to any command unless the Clock Card is also reprogrammed.

• Always cleanly reset the MCE after a power-up or a reconfiguration! If not, MCE communication with the PC or Sync Box may not work. On MAS prompt, type: mce_reset_clean

• After an mce_reset, not all of the DAC outputs are set to zero. In addition, values written to RAM-based registers are not reset. A full reconfiguration is required for a proper reset. You may power-cycle the MCE remotely if the MCE is equipped with a PSA (UBC switching supply) by issuing mce_cmd -x rs psc cycle_pow 1 and then mce_reset_clean

Releases

All firmware can be downloaded from http://e-mode.phas.ubc.ca/mce_firmware/. Release notes for each firmware release can be found below:

• Clock Card (CC)
• Readout Card (RC)
• Bias Card (BC)
• Address Card (AC)
• Power-Supply Unit Controller (PSUC)
• Sync Box Firmware

Firmware Upgrade Methods

There are two ways to upgrade the MCE firmware:

1. Remote firmware update over the MCE fibre interface
2. Using Altera-supplied Hardware/Software and MCE Front-panel Connector
   • step-by-step instructions
