Firmware version notes
Latest release: U0105 (2009-06-08)
- Backward compatible with U0104.
- Support for MCE STOP commands and commands-on-the-fly.
- Accelerated MCE command code (along with Quiet-RP this increases commanding rate to ~6 kHz).
- Quiet-RP simplifies the protocol for MCE reply handling.
- Low-level improvements:
- CON is done as PCI burst
- Fibre-optic FIFO is emptied with timed read instead of polling.
- Hand-shaking for interrupts instead of host command to clear INTA and HC3.
- Non-interrupt context code disables interrupts when performing PCI transactions.
- Host vector interrupts are otherwise enabled, so PC doesn't have to force with HNMI bit.
Last stable version: U0104
- Implements quiet transfer mode! Remains backwards compatible with A1.4.
- Fixes the 64k boundary crossing issue
- Moves parameters that enter via interrupt out of registers and into variables
- Version reporting tag-along to RDM command (sending 'VER' to RDM's vector address returns the code version).
- Maximum burst length is reduced to 64 bytes, and is configurable.
- Reset (RST) clears the fibre fifo
Oldest UBC release: U0103
- Minor modifications of SCUBA2's A1.4 firmware, to improve PCI stability.
- Not compatible with non-realtime systems.
