Hello all,
just see with current HEAD of u-boot on an imx6ull based board with SPI NOR and NAND following behaviour:
=> mtdparts
device nand0 <gpmi-nand>, # parts = 1 #: name size offset mask_flags 0: ubi 0x08000000 0x00000000 0
device nor0 <spi1.0>, # parts = 5 #: name size offset mask_flags 0: spl 0x00010000 0x00000000 0 1: u-boot 0x000c0000 0x00010000 0 2: env 0x00010000 0x000d0000 0 3: env-red 0x00010000 0x000e0000 0 4: rescue 0x00710000 0x000f0000 0
active partition: nand0,0 - (ubi) 0x08000000 @ 0x00000000

until here all is fine, for example an "ubi part ubi" works as expected ... also doing this command n times, no problems.
Now:
=> sf probe SF: Detected s25f064l with page size 256 Bytes, erase size 64 KiB, total 8 MiB => mtd list List of MTD devices: * nand0 - type: NAND flash - block size: 0x20000 bytes - min I/O: 0x800 bytes - OOB size: 64 bytes - OOB available: 0 bytes - ECC strength: 8 bits - ECC step size: 512 bytes - bitflip threshold: 6 bits - 0x000000000000-0x000008000000 : "nand0" - 0x000000000000-0x000008000000 : "ubi" * nor0 - type: NOR flash - block size: 0x10000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000000800000 : "nor0" =>
All MTD devices on nor0 are gone ... also the previous working "ubi part ubi" fails ...
Adding debug code:
mtd_for_each_device(other) printf("%s ===== %s\n", __func__, other->name);
shows only:
get_mtd_device_nm ===== nand0 get_mtd_device_nm ===== nor0
?
Anyone sees this behaviour too?
Any hints?
