Compatibility

Version 1.5 of the AIO-16 FPGA requires version 1.5.4 or later of the AIO-16 firmware. Although version 1.5 of the FPGA might work with earlier versions of the AIO-16 firmware, it might also result in the AIO-16 card continually resetting.

Updating the FPGA image

• In AZedit, go to Status | Software Versions | IO Cards.
• Download version 1.5.4 (or later) of the AIO-16 firmware to the target cards.
• Wait for the cards to reprogram themselves and reset.
• Verify that the cards are running the correct version of firmware. Verify that they report the expected FPGA version.
• Download version 1.5 of the FPGA to the target cards.
• Wait for the cards to reprogram themselves and reset. (The cards will still report that they are running the earlier version of FPGA.)
• Manually reset each card that has been downloaded (which forces the FPGA to be reloaded).
• Verify that the cards report that they are running FPGA v1.5.

Version 1.5

A problem in FPGA v1.4 results in the MCII-e recording excessive control bus errors when trying to communicate with the AIO-16, especially when the active controller is the one in the default-standby slot (the right-hand controller in ADAM frames; the lower controller in ADAM-M frames).

FPGA v1.5 fixes the control bus errors.

Version 1.4

With older versions of FPGA, a timing violation when accessing the SRAM memory device could cause memory corruption. This would typically result in a keypanel connected to port 7 or 15 to stop responding, and display "****" on all keys. Because of the random nature of the memory corruptions, other symptoms were also possible.

The timing problem only affects AIO-16 cards manufactured after August 2007.

FPGA version 1.4 fixes the timing violations and eliminates the memory corruptions.
