Support for BCM953012HR board?

How do I build the images for BCM953012HR (Broadcom Northstar Reference board)?

Hello,

You need to create a Buildroot configuration that matches your platform, i.e that defines the target CPU, the Linux kernel version and configuration, the filesystem image format you need, etc. Once this configuration is defined (which is obviously the difficult part), build it with "make" and enjoy the build results in output/images/.

Best regards,

Thomas

Hi,

I took care of adding upstream Linux support for a few Northstar hw components. Current support is quite complete except for:
1. Hardware NAT acceleration
2. Broadcom SoftMAC wireless chipsets

I planned to add buildroot support for Northstar boards but it takes many months to get my patches reviewed.

My initial WiFi firmware patch was accepted after 5 months:
[PATCH] package/linux-firmware: add options for Broadcom BCM4366 Currently I'm waiting for lzma-alone decision:
[PATCH] package/lzma-alone: new package

Once I get lzma-alone somehow merged I'm planning to add Northstar boards support.

Until that you can check OpenWrt project. It has target called "bcm53xx" that handles Northstar devices. There are only few downstream patches needed to get those devices running:

Rafa?

Thanks for your valuable suggestion. I have checked the targets supported by openwrt for Northstar processors. It provides kernel and rootfs builds for Northstar based boards. (tried MR32)
I am unable to find the u-boot build for the Northstar based SoCs. How do I enable the u-boot build as well for any of these boards?

It would be great to see the support for Northstar boards in the buildroot
as well.

I've never seen Northstar device using u-boot. I heard about some rough plans for porting u-boot to it, but I thought they got abonded.

Can you provide bootloader log from your board?

Rafa?

Please find the attached bootlog (This is a custom board, based on
BCM53016).
