Hi,
We built a custom board based on the Rubik Pi 3 to use more peripherals (UART11 and SPI6).
To enable them, I cloned the Ubuntu kernel source, updated the DTS node configurations, and built combined-dtb.dtb.
However, after flashing the DTB, the system fails to boot. The error logs are attached below.

rubikpi-issue-spi6-cut.txt (3.2 KB)
According to the TurboX UART and SPI Development Guides, this issue appears to be an “Identify TZ Configuration Issue.”
Since we don’t have a way to modify and build the TrustZone (TZ) firmware ourselves, could you please advise on how we can address or work around this problem?
Our FAE suggested posting this issue on this forum for further assistance.
Thank you.
