U-boot integration fails on custom i.MX35 board

Sorry for bothering again, my original problem seems not to have been resolved. If I set

MENDER_STORAGE_DEVICE = “ubi0”

then everything compiles and bootes fine, but when I run mender from the command line, there is following error:

WARN[0000] Could not resolve path link: ubi0_0 Attempting to continue module=partitions
WARN[0000] Could not resolve path link: ubi0_1 Attempting to continue module=partitions

This is no wonder, as I can see in the auto-generated mender.conf that the paths are wrong:

{
“InventoryPollIntervalSeconds”: 1800,
“RetryPollIntervalSeconds”: 300,
“RootfsPartA”: “ubi0_0”,
“RootfsPartB”: “ubi0_1”,
“ServerURL”: “https://docker.mender.io”,
“TenantToken”: “dummy”,
“UpdatePollIntervalSeconds”: 1800
}

changing from ubi0_0 to /dev/ubi0_0 omits this error, but then mender -rootfs will not work.

If I otherwise set

MENDER_STORAGE_DEVICE = “/dev/ubi0”

I get the error described in my first post.

How can I correctly set different paths to the UBI volume for Linux and U-boot respectively ?
Searching through the docs made me think adding

MENDER_UBOOT_STORAGE_DEVICE = “0”
MENDER_UBOOT_STORAGE_INTERFACE = “ubi”

would do the trick, but there is no difference.

Do you have any advice ?
