'git besect' shows that commit 898ed91 breaks the things. A debug version of U-Boot log is: => sf probe uclass_find_device_by_seq: 0 0 - -1 -1 - not found spi_find_bus_and_cs: No bus 0 uclass_find_device_by_seq: 0 0 - -1 -1 - not found uclass_find_device_by_seq: 1 0 - -1 -1 - not found Invalid bus 0 (err=-19) Failed to initialize SPI flash at 0:0 (error -19) Command failed, result=1=> Regards, Bin _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
