Why do I see the HPS on Intel Agilex® SoC devices fail to boot, or observe some unexpected functional failures at run time?

Description

Due to a problem in the device manager firmware, you might fail to read/write certain RAMs on some Intel Agilex® SoC devices. Impacted HPS RAMs include L2 cache, OCRAM, CCU, USB, CoreSight, and EMAC.

You might observe the following HPS boot failures:

• HPS hangs at dcache memory write and read after executing the dcache_enable function in FSBL
• UART printout stops after “DDR: 8192 MiB”
• UART printout stops after “Loading Environment from MMC… ***”
• UART printout stops after “Verifying Hash Integrity … crc32”
• Various unexpected functional failures depending on the faulty RAM location

Resolution

To resolve this problem, update to the latest device manager firmware for the Intel® Quartus® Prime Pro Edition Software v21.2, 21.3, 21.4, 22.1, and 22.2. 

 

The latest device manager firmware is available from the following link:

This problem is fixed beginning with version 22.4 of the Intel® Quartus® Prime Pro Edition software.
