Why are GTS transceiver tests including PCIe* enumeration failing on the Agilex™ 5 FPGA E-Series 065B Modular Development Kit (MK-A5E065BB32AES1)?

Description

Due to a change in the Agilex™ 5 FPGA E-Series 065B Modular Development Kit (MK-A5E065BB32AES1) manufacturing test process, some boards have a corrupted FPGA image stored in the FPGA QSPI flash.  This corrupt image results in failures in transceiver operation even if a new image is loaded via JTAG.  Examples of issues include failure of the PCIe* to enumerate and SFP transceiver loopback tests failing.  

Resolution

To fix this problem, follow these steps

1. Ensure that the MAX® 10 FPGA POF image is updated as described in this KDB: Why does the GTS AXI Streaming IP for PCI Express* design example for Agilex™ 5 FPGAs fail to operate and enumerate in hardware when loaded from QSPI on the Agilex™ 5 FPGA E-Series 065B Modular Development Kit (MK-A5E065BB32AES1)?
2. Download ghrd_a5ed065bb32ae6sr0_hps.jic to a host computer with the Quartus® Prime Pro Edition Programmer v25.3 or newer to update the Agilex™ 5 FPGA E-Series 065B Modular Development Kit FPGA QSPI flash. 
3. Set the Agilex™ 5 FPGA Modular Development Kit carrier board switch S13-3 and S13-4 to "OFF" so the USB JTAG option is selected and the Agilex™ 5 FPGA is on the JTAG chain. See switch setting in this photo:

4. Connect the micro USB cable to the Agilex™ 5 FPGA Modular Development kit front panel JTAG connector (J35) and attach other end to host computer.
5. Bring up the Quartus® Prime Pro Edition (25.3 or newer) Programmer GUI, select "Auto Detect" .  Your display should be similar to the one shown below:

6. Select the A5EC065BB32 device, right click and change file to ghrd_a5ed065bb32ae6sr0_hps.jic.  Select "Program/Configure" and "Verify" for the MT25QU02G device as shown below:

7. Click "Start" to begin the programming process.  The programming process takes approximately 5 minutes to complete.
8. Power cycle the board for the new image to be loaded. 

 

This manufacturing problem is resolved in production versions of the Agilex™ 5 FPGA Modular Development Kit.
