Bootloader Fails to Run with UART0 Disabled - Bootloader Fails to Run with UART0 Disabled Description 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. Resolution 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 Custom Fields values: ['novalue'] Troubleshooting novalue True ['novalue'] ['FPGA Dev Tools Quartus II Software'] novalue 13.0 ['Arria® V FPGAs and SoCs', 'Cyclone® V FPGAs and SoCs'] ['Embedded Dev Tools SoC Suite'] ['novalue'] ['novalue']
