1.9. Altera® FPGA SDM Firmware

Quartus® Prime Pro Edition Version 25.1.1 includes new SDM firmware features as well as fixes.

When regenerating your configuration bitstream, use the latest version of the Quartus® Prime Pro Edition software, which includes the latest firmware. You do not need to recompile your .sof to use the firmware from a newer version of the Quartus® Prime Pro Edition software. You can regenerate your configuration bitstream with the new version of the Programming File Generator.

General improvements and fixes for F-Tile devices. For devices with F-tile, .sof files and Quartus® Prime Pro Edition Programmer must both be upgraded to 25.1.1 when creating bitstreams for devices. Configuration N/A N/A
Reported UIB REFCLK timeout causes configuration to fail. For HPS First 2nd stage reconfigurations, a UIB REFCLK timeout may be observed, halting configuration due to a firmware issue. Configuration N/A N/A
Device may become stuck in configuration mode after successive reconfigurations. For the Avalon-ST (AVST) configuration scheme, in rare cases, successive reconfigurations may cause the device to hang. The fix includes an update to the firmware polling scheme to address this issue. Configuration N/A N/A
Intermittent configuration failure after many power cycles. In the Active Serial (AS) configuration scheme, repeated power cycles may cause the device to report an internal error and fail to configure. Configuration 00912060 N/A
