/sbin/depmod: Command not found

[IniterWorker]

Hello,

I'm using the warrior revision of poky. I don't think it's a big deal in this issue. I'm wondering if you know about this issue of /sbin/depmod: Command not found. Do you have any idea about the dependency problem?

I tried to install the native kmod package from my docker container. I walked one step forward but I didn't get a full build because now the build uses the native to compute the target depmod operation.

[LetoThe2nd]

Looks very much like you the Makefile of the kernel modules you are trying to backport needs fixing. Especially the hardcoded path to /sbin/depmoddoesn't only scream for trouble but actually cause you the headcahes that you are seeing. I suggest to get rid of about everything besides the actual compile command, and let bitbake figure out the module packaging, we have mechanisms for that. Find more inforamtion here

[IniterWorker]

@LetoThe2nd, I'd like to thank you a lot for your advice.

I got a build. But, I don't have much time to handle the test. I have some trouble with sysupgrade. I don't know how to use it correctly. Because I have tried to flash an ubifs, but I didn't get a boot. Some shitty magic code maybe unallowed by the u-boot of the product provider. Maybe, @micro-iot, could you share some examples about flashing your device?

B.r

[LetoThe2nd]

@IniterWorker I would love to help, but flashing procedures are highly board specific, and I have never used that board, not even touched anything MIPS for over 10 years - Sorry. Your best chance is to reach out for @micro-iot as they seem to have experience concerning that board.

[micro-iot]

@IniterWorker Linkit Smart 7688 needed only downloading via TFTP and flashing (option nr. 2) in u-boot console, which was the original one supplied by Mediatek.

[IniterWorker]

@micro-iot, can you describe a bit of your procedure in terms of command line? I don't have the mt7688. I have the mt7620.

Thanks for your advice.
