I'd like to get OpenWRT running on my Arris NVG468MQ. It has a Broadcom BCM63148 as the main SoC, a Broadcom BCM43602 for the 2.4GHz radio, a Quantenna QT3840BC for the 5GHz radio, and an Entropic EN2810 for MoCA. Some source code is available. There are several conveniently-labeled serial ports on the board, although I haven't tried them yet since I'd have to solder onto them. The firmware doesn't seem to listen for SSH connections.
So... what next? Assuming one of those serial ports lets me break into the boot process, how do I go from there to installing OpenWRT? Are these components supported well enough to even bother? Will I be able to run a second copy of OpenWRT on that Quantenna chip once the main SoC is working?
The SOC will be rather slow (depends on proprietary acceleration, without it, routing throughput is 'limited'), 2.4 GHz WLAN should kind of work, in a limited fashion (brcmfmac), 5 GHz wlan is never going to work, nor is MoCA.
Indeed I would. Uh, you wouldn't happen to know if one of the existing targets fits the BCM63148, would you? It looks like bcm63xx was replaced by bmips, but this is an ARM SoC, not MIPS.
You seem to have a strange idea of 'fun', but hey a wlan 'driver' (qtnfmac) is already there, but it misses the hard-required corresponding firmware, which onsemi hasn't bothered to release in the last 7 years - and I feel pretty safe that you won't get to see it within the next 70+ years either.
…and for MoCA, you'd be starting with the birds and the bees.
Arris was kind enough to bundle the entire SDK for building the Quantenna firmware (mostly) from source, so aside from possible license issues I think that part's covered.
'Cool', no need to tell me when you realize that qtnfmac needs a different -still MIA- firmware blob, than the old vendor driver. While it might surprise you, this topic about QT3840BC might have come up before already.
