Special QSPI boot considerations for XQ family?

Jump to solution

We have a design that works with a XCZY6CG-FFVB1156-1L-i. We're trying to migrate to an XQZU9CG-FFQB1156-1l-i (extended temperature grade). That latter refuses to boot from QSPI. Is there something we need to do differently on the XQ family to allow booting from QSPI?

When we try to boot from QSPI, nothing appears to happen. Xsct shows that the procsesors are held in reset. We are able to boot from JTAG and download and execute an FSBL. The FSBL was generated in XSDK from a hwdef file for an xczu9cg-ffvb1156-1L-i, because we can't find the XQ9CG family in the supported parts in Vivado 2018.3. Using the program_flash tool, we are able to program and verify the boot image.

Does the XQ family perhaps have anti-tamper protection features turned on at the factory that prevent QSPI booting from an unencrypted image?

We figured out our problem: looks like user error. We re-generated HDF and FSBL from scratch, and things started working.
