Hi,
I have an armada 370 device, and the commit on 2019-03-25 (commit id: 8dcc1087602e2dd606e4f6e81a06aee62cfd4f4c) caused the my device got a kernel panic, and this commit is effecting all the gcc versions (gcc 7.4, 8.3 and 9.2)

Any idea about this? Thanks.

Works here with Armada, as well as everybody else have it working, so please run "make dirclean" and compile everything from scratch. This change requires one to recompile ALL the source with no exceptions. Please make sure build_dir and staging_dir empty before starting compilation.
Preferably remove all customizations and do clean build from upstream source.

Thanks for reply.
What I've tried with no success:

1. make dirclean;
2. change gcc version (7.4, 8.3, 9.2) with make dirclean;
3. change the build host system (opensuse 15.1, ubuntu 18.10) with fresh git clone;

What I've tried with success:

1. change hardware floating to software floating;
2. change the gcc back to before commit 2019.03-25 (gcc 8.3.0 with hardware floating).
4

There was a change to the .config options, which required doing as stated in the commit message you specified above.

5

I wonder where this comes from?

WARNING: Variable 'network' does not exist or is not an array/object
WARNING: Variable 'lan' does not exist or is not an array/object

seems like something very wrong with your configuration or ubus scripts, I would guess due to the changes made to default OpenWRT default configuration.

6

These warnings caused by the libjson-c.so.4.0.0, I tried to replace the libjson-c.so.4.0.0 from old build, and the warnings were gone.

7

So sounds like your problem are around libjson, not sure why.
Which branch are you using?

I remember there was an issue with ubus for some packages some time ago that was causing similar errors.

8

I'm using the trunk branch, acctully I've tried to replace the libjson-c from openwrt's latest prebuild version, and I got the same issue (even though I replaced the old libjson-c, the kernel panic was gone, but still a lot of program got "Illegal instruction" like dnsmasq...)
So I guess the commit break the hardware floating (maybe only for armada 370).

9

Well, OpenWRT mvebu target assumes Cortex A9 CPU, but no datasheet I could find says that Armada 370 is Cortex A9, the only thing could find is that it s ARMV7 architecture but that is not good enough, you might need to get documentation from Marvell on which CPU it actually is.

10

I'm an end user, so ...
But my device is working very well before that commit.

11

Maybe this can help:

EBU Armada family

Armada 370 Flavors:

  • 88F6710
  • 88F6707
  • 88F6W11

Core:
Sheeva ARMv7 compatible PJ4B

link:https://www.kernel.org/doc/html/latest/arm/marvel.html

12

Yeah, you're most likely running into issues because of that. The kernel config might also be a bit wrong for that platform.

I guess you could try chainging https://github.com/openwrt/openwrt/blob/master/target/linux/mvebu/cortexa9/target.mk#L12 to marvell-pj4 and remove subtype no idea if it helps however.

13

Thanks. I'll get a try.

14

15

You forgot to leave subtype blank. This is why you hard-float issues.

And I am not sure other parts of OpenWRT makefiles understand marvell-pj4 correctly.

16

And you need to remove FPU from features, on mvebu Makefile. 1 level up.

17

But the armada 370 acctully have FPU....

18

Yes, sorry I misread the error message. The error was that FPU enabled, but no FPU type (subtype). For this CPU subtype should be vfpv3 as before.

19

I've tried the marvell-pj4 with vfpv3, and build the openwrt successfully, but my device still got the same issue:
