Hi,
I got following error message when using U-Boot as payload of Coreboot on Intel DNV-NS platform. I am checking if my dts file was incorrect configured for SPI flash device. Can anyone help? Thanks. Errors: Invalid bus 0 (err=-19) Failed to initialize SPI flash at 0:0 (error -19) ==================================== My dts dump: aliases { serial0 = &serial; spi0 = &spi0; }; config { silent_console = <0>; }; chosen { stdout-path = "/serial"; }; tsc-timer { clock-frequency = <1000000000>; }; pci { compatible = "pci-x86"; u-boot,dm-pre-reloc; pch@1f,0 { reg = <0x0000f800 0 0 0 0>; compatible = "intel,pch9"; u-boot,dm-pre-reloc; #address-cells = <1>; #size-cells = <1>; spi0: spi { #address-cells = <1>; #size-cells = <0>; compatible = "intel,ich9-spi"; intel,spi-lock-down;
