Very urgent question about kobs-ng

[shun12a]

the uuu scripts: when i was used FBK: ucmd kobs-ng init -x -v --chip_0_device_path=/dev/mtd0 /tmp/u-boot-dtb.imx it will be show up

[shun12a]

Is there anything I didn't configure? I'm using the official kobs-ng

[allenxh]

Any uuu side log?

It appears in uuu unable to create a temporary file,But the previous xml did

[allenxh]

Please try uuu built-in nand command “-b nand” to burn this uboot, to see if it works.

built-in nand command “-b nand” will still appear

I'm using the 2019 SDK version of MX6ULL,But I replaced kobs-ng, is it related to the version

[shun12a]

Do you have any ideas? There is a real urgency to this problem

[allenxh]

I haven't used the tmpfs, please check if the patch can fix the problem.

[shun12a]

It has been solved. I hope I can have some ideas for you. I need to enter the tmp directory before I can perform burn writing

[shun12a]

I don't know why, but I can execute it directly in nand mode

[shun12a]

Thanke for your help

[allenxh]

Glad to help!
