Contents
1.4.1
- Filename : bc_v01040001_25jan2008.sof or .pof
- Feautres :
- added card_type and scratch commands
- integrated fw_rev and slot_id as part of all_cards
- added provisions for safe state machines to fix the reset problem.
- added lvds_tx = 0 so clock-card can check whether the card is plugged in using this spare lvds line.
1.4.0
- Filename : bc_v01040000_14dec2007.sof or .pof
- Feautres :
- added flux_fb_upper command to be able to test the mcev2 subrack and set bias only for the upper 16 channels
1.3.7
- Filename : bc_v01030007_07mar2007.sof or .pof
- Feautres :
- fpga_temp bug is fixed.
- Bugs :
- Sometimes the card is not responsive after a reset. This was diagnosed as being related to non-safe FSMs.
- Sometimes the wb bias command only loads half of the value to the DACs, i.e. the voltage is half of what expected on the MDMs. This is resolved in 1.4.1.
to-do list
- the DAC clocks are driven through a counter, but they should be driven off a PLL 12.5MHz
