RT3662 NAND support
Hi, I'm trying to add support for an older ZWave bridge, the MiCasaVerde Vera Lite (similar or equal to SERCOMM NA300). It's based on RT3662, 64MB RAM and 32MB NAND flash - and this is where I'm currently stuck. The rt3883.dtsi does not define a NAND controller and I'm unsure whether there actually is a suitable driver. How can I best find/add a NAND driver for RT3662, or is it not worth the effort? Thanks ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Good question, especially without the datasheet or any piece of code to look at. If you are up for a lot of hard work, a starting point could be here: https://github.com/openwrt/openwrt/pull/597 MT7620 was the successor of those SoCs, I would guess the NAND controller is probably very similar to this one. MT7621 is a more different design of NAND controller which came after, and as you can see in the PR, the "old" MT7620 NAND was never cleaned up nor merged into OpenWrt. For you it could still be worth the shot, if you find the full datasheet of RT3662 somewhere you can compare with MT7620 (which is easy to find).

Unfortunately, you just confirmed my suspicion that there is no easy way to have NAND support. My impression is that there is very little interest in these older Vera devices, so I'll go for initramfs + extroot for now (fortunately, there is a USB port).

Hi little of topic but are there some z-wave bridges that are already supported by the openwrt? And if you boot openwrt to vera lite via USB, are you able to see/use the z-wave controller from that device?

I can give you a partial answer: I'm also working on the SERCOMM NA502 and NA502s that are also sold as Vera Secure, Smart Home by Hornbach, A1 Smart Home Gateway and a few other brands (I have the A1 branded version). Basically, I've got ZWave running, you can track the status here: https://forum.openwrt.org/t/adding-support-for-sercomms-na502/22495 Regarding the Vera Lite, I'm still investigating the possibilities and have not yet booted any custom firmware. I don't see a reason why the ZWave controller shouldn't be visible (it's attached to a UART). However, I found only limited information in whether this particular controller is supported by OpenZWave or Z-Wave JS. My ultimate goal with both SERCOMM devices is getting ZWaveJS2MQTT running so that a home automation software can talk to the gateway.

Or you can also just buy an usb based aoetech z-stick or similar and use that instead, for example on a pi. It is already working well with zwavejs2mqtt plus home assistant and doesn't need any hw/sw hacking to get it working so probably less effort but of course costs a little compared to something you might already have. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
