[CC u-boot ML since it may not be a kernel only related bug(s)] Hi Richard, Artem,
I'm still playing with fastmap and I ran into something. It's involving u-boot's "ubi write" command and fastmap. What I'm doing is: - Flashing a mtd partition with a userspace.ubi image via u-boot - Booting linux one or to times - Flashing the UBI volume rootfs with a rootfs.ubifs image via u-boot - Booting linux one or to times. And, depending on fastmap not compiled/disable/auto I've got an ubi_assert that fails and a slowpath warning. Here's the story: U-Boot 2013.07 Kernel 3.11.1 NAND: - 128KiB PEB - 2KiB page - 2048 PEB - no subpage mapping is: 0x000000000000-0x000000020000 : "dtb" (128KiB) 0x000000020000-0x000000a00000 : "Kernel" (9.875KiB) 0x000000a00000-0x00000ff80000 : "UBI" (245.5 KiB) 0x00000ff80000-0x000010000000 : "BBT" (512KiB) 1- With Fastmap NOT compiled - Flashing the UBI mtd partition under u-boot: >fatload usb 0 0x20008000 /userspace.ubi >nand device ubi >nand erase.part ubi NAND erase.part: device 0 offset 0xa00000, size 0xf580000 OK > nand write.trimffs 0x20008000 ubi 35a0000 NAND write: device 0 offset 0xa00000, size 0x35a0000 56229888 bytes written: OK Booting a non-FASTMAP kernel: [...] [ 0.789062] UBI: attaching mtd2 to ubi0 [ 1.351562] UBI: scanning is finished [ 1.367187] UBI: attached mtd2 (name "UBI", size 245 MiB) to ubi0 [ 1.375000] UBI: PEB size: 131072 bytes (128 KiB), LEB size: 126976 bytes [ 1.382812] UBI: min./max.
