PCI card firmware

Download

These S-record files should work with any reasonable EPROM programmer:

• U0105 (latest) - http://e-mode.phas.ubc.ca/~mhasse/mce/arc_pci/SDSU_RevU0105.s
• U0104 (stable) - http://e-mode.phas.ubc.ca/~mhasse/mce/arc_pci/SDSU_RevU0104.s

The full source code is available in these archives (it will not compile unless you get the correct assembler and stuff):

• U0105 - http://e-mode.phas.ubc.ca/~mhasse/mce/arc_pci/arc_pci-U0105.tar.gz
• U0104 - http://e-mode.phas.ubc.ca/~mhasse/mce/arc_pci/arc_pci-U0104.tar.gz

The subversion tree can be obtained like this (you may not have access to this repository; contact UBC);

svn checkout svn://e-mode.phas.ubc.ca/arc_pci

It is laid out roughly as follows:

/trunk       main line of development
/releases    tagged versions of code 
/tools       debugging tools
/clash       stuff for making CLAS work with wine and linux
/docs        useful (though maybe not to you) notes

Firmware version notes

Next version: U0106 (testing)

• Backward compatible with U0104 and U0105.
• Fixes bug introduced in U0105 that prevented handling of some PCI bus errors.
• Introduction of command to update PCI burst size.

Current stable version: 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.

First version with non-realtime linux support : 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.
