Firmware Revision Listing
Revision 5.0.2 (lab use)
- Filename
- bc_v05000002_xxjan2010.sof
- Features
- build based on 5.0.1 for Rev. E cards
- Independent control for ln_bias lines 0 to 11
- Details
- If this firmware is loaded on a Rev. D card, it's harmless. The only functionality loss is that the bias command will not work as unfortunately DAC CS and CLK pins are swapped for the bias DAC between the two revisions of the card.
- To do
- fix combinational loops on read-ram register
- Bugs
Revision 5.0.1 (lab use)
- Filename
- bc_v05000001_19jan2010.sof
- Features
- supports the new low-noise bias lines (total of 12) introduced in Bias Card Rev. E
- card_type parameter is set to 5 (bias-card Rev. E)
- All DACs are loaded at once as oppose to previous revisions that loaded them one after next.
- DAC clock is now 25MHz and generated by PLL, previous firmware had 12.5MHz clock generated by dividing down.
- Details
- If this firmware is loaded on a Rev. D card, it's harmless. The only functionality loss is that the bias command will not work as unfortunately DAC CS and CLK pins are swapped for the bias DAC between the two revisions of the card.
- To do
- All ln_bias lines are controlled at once and this should be modified to independent control.
- Bugs
ln_bias_0 doesn't work, because the data line for ln_bias_0 is not connected in firmware.
Revision 5.0.0
- Filename: bc_v05000000_22dec2008.sof (tagged as sys_v05000000_22dec2008)
- To Do:
- Features:
- IMPORTANT: Must be used in conjunction with firmware v05000000 of all other cards!!!
- To allow enough data bandwidth, the spare LVDS line from each card to the Clock Card is now used
- Details:
- Bugs:
- None yet reported

Revision 1.4.2
There is no information on this.
Revision 1.4.1
- bc_v01040001_25jan2008.sof
Features:
- 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.
Bugs: None so far
