ZCU208 Board Not Booting from SD Card During SoC Blockset Hardware Setup

Hi

I was setting up the SoC Blockset Support Package for AMD FPGA and SoC Devices with a ZCU208 RFSoC board, but the board fails to boot from the SD card during hardware setup.

I followed the MATLAB hardware setup wizard to write the SoC Blockset image onto the SD card after formatting it. I set the board to SD boot mode before powering it on. However,the DONE LED remains red, and the serial console (PuTTY @ 115200 baud) shows the following error messages:

Retry time exceeded; starting again

When I try to load other images provided by AMD, the board boots and responds normally. Any help is appriciated. Thank you!

Hi @Aiswarya,

I faced a somewhat similar issue. You can try out these few troubleshooting steps:

• Check SD Card Compatibility: Use a reliable SD card (8–32 GB, Class 10 recommended). Some cards may fail during boot.
• Inspect Boot Files on SD Card: After flashing, confirm that the SD card contains BOOT.BIN, image.ub, and boot.scr in the root directory. Missing files will trigger PXE boot errors.
• Update SoC Blockset Support Package: Make sure you have the latest version of the SoC Blockset Support Package for AMD FPGA and SoC Devices installed.
• Close Conflicting Applications: Ensure no other application is using the serial port while MATLAB communicates with the board. Close such apps and retry the step.

I hope it helps.
