Critical Issue
In v13.1, even if UART0 is disabled in the HPS component, the preloader generator turns on spl.performance.SERIAL_SUPPORT (UART0 serial I/O support).
In v13.0, even if UART0 is disabled in the HPS component, the preloader generator turns on both spl.performance.SERIAL_SUPPORT (UART0 serial I/O support) and spl.reset_assert.UART0 (UART0 reset support).
As a result of these errors in preloader settings, when the preloader passes control to the bootloader, the bootloader might not run correctly. For example, U-boot hangs.
Depending on whether UART0 is enabled, manually enable or disable the following preloader settings:
- spl.performance.SERIAL_SUPPORT-UART0 serial I/O support
- spl.reset_assert.UART0-UART0 reset support
