Hello Simon, U-Boot HEAD qemu-86_defconfig cannot discover an IDE disk with one FAT partition in qemu-system-x86_64.
By bisection I found this patch. b7c6baef2891ce8978cbfddb66e944943473ac21 x86: Convert MMC to driver model With this patch I get IDE: Bus 0: OK Bus 1: OK Device 0: Model: QEMU HARDDISK Firm: 2.5+ Ser#: QM00001 Type: Hard Disk Supports 48-bit addressing Capacity: 128.0 MB = 0.1 GB (262144 x 512) ** Can't read Driver Desriptor Block ** Device 1: not available Device 2: Model: QEMU Firm: 2.5+ Ser#: QEMU DVD-ROM Type: Removable CD ROM Capacity: not available Device 3: not available => ide info => Without the patch I get=> ide info Device 0: Model: QEMU HARDDISK Firm: 2.5+ Ser#: QM00001 Type: Hard Disk Supports 48-bit addressing Capacity: 128.0 MB = 0.1 GB (262144 x 512) Device 2: Model: QEMU Firm: 2.5+ Ser#: QEMU DVD-ROM Type: Removable CD ROM Capacity: not available I think we observe two independent errors here: - The hard disk Device 0 is not read. - The ide command stops at the first device that is not available. I guess only the first is caused by your patch. Best regards Heinrich _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
