[LEDE-DEV] ubi images with lantiq

[Florian Eckert]

Hello Lede-Team

We have developed an own layout with the lantiq xrx200 soc. For now we
are useing the openwrt 15.05 Branch.
I have evaluated the lede tree on our board.

After some try an error the system is now booting with lede but only
with jffs2 support

mtd layout openwrt with ubifs
- uboot
- uboot_env
- kernel
- ubi

mtd lyout lede with jffs2
- uboot
- uboot_env
- fimware

I have enabled to build an ubi based firmware, but the firmware is
always an jffs2?

Does lede decieded to standardize only have jffs2 support for alle
arch targets? Who can i get ubifs support back on image generation?.

Regards

Flo

[LEDE-DEV] [PATCH] procd: instance_stop causes a call to instance_removepid via instance_exit, no need to do this already when the instance will be stopped.

Re: [LEDE-DEV] MT7621: 2 or 4 CPUs?

[Gaetano Catalli]

Thanks Daniel,

I also found it in the datasheet:

MIPS MT Application Specific Extension (ASE)
  - Support for 2 Virtual Processing Elements (VPEs) per CORE
  - One Thread Context (TC) per VPE

Regards,
Gaetano

MIPS MT is similar to Intel's HyperThreading on x86.

[LEDE-DEV] MT7621: 2 or 4 CPUs?

[Gaetano Catalli]

Hello,

I'm a bit confused about the number of CPUs of MT7621 SoC.
>From the MT7621 datasheet:

"The MT7621 router-on-a-chip includes a 880 MHz MIPS 1004Kc CPU dual-core ..."

So why does /proc/cpuinfo show 4 cpus?

Regards.

Individual kernel-configs would again increase the number of build
configurations, so that's not an option.

OK, I guess it makes sense to have router/nas subtargets then.

In the image building code, a Device/* section can override the
filesystems that are built for the device, using the FILESYSTEMS variable.

ramdisk images might still be useful.
