Re: CM3+ Released with up to 32GB eMMC

Hi

Nice news, well done guys

Does the new CM3+ require any changes to the dtblob.bin setup file?

i.e. Will it key off the pins_cm3 section still or will it be looking for pins_cm3plus ?

Which OS and kernel/firmware revision is the minimum that will support the new Chip?

Thanks

Andrew

Re: New "gpio" config.txt command announcement

This is great!

We’re a step closer to not needing custom device tree blobs in our compute module application now :D

Any chance you can do something for camera (dual) configuration in a similar style?

Re: Moving Linux kernel to 4.14

Hi We're running a CM3 on a custom carrier board we've had for a few years now. Has been running quite happily up to 4.9.75, no problems. All Solid. I've just done a rpi-update running on Jessie to test out the new 4.14 kernel and the system hangs on next boot up : https://gist.github.com/anonymous/...

Re: external watchdog on GPIO output

What I mean is This sounds like if we have an external watchdog chip (e.g. STWD100PYW83F) hooked up to GPIOs 26 (Watchdog enable) & 25 (Watchdog input) we could use a modified version of the config in your posts to allow us to use the rather nice watchdog module, with the range of conditionals in /e...

Re: external watchdog on GPIO output

Hi Am I understanding this correctly that you can use any GPIO line (subject to default pull being correct) for external watchdog operation with this? i.e. the module doesn't make use of RPi PWM to do the watchdog pulse timer but rather this is controlled/generated by the Linux OS/Kernel So for exam...

Was that done by doing this :

Presumably that means you can also get the CM3 running the same way if you blank out the eMMC after running?

Does that mean you can boot Windows 10 IOT?

Re: Ethernet via SDIO

Ok, so how do you hang two LAN9512 controllers off a single 480M USB port while leaving all eight of their ports free?
I would start by extending the bus via a cheap USB hub chip myself, then connect up the appropriate combination of LAN9512/9514 chips as desired. :)

Re: Ethernet via SDIO

That would only give you 7x USB and 2x Ethernet (the second LAN9514 would have to daisy-chain of one of the USB ports in the first one. So it doesn't quite meet the OPs requirements.. You might have thought that, but that's not what I said... . Also, hanging 8 x 480Mb USB + 2 x 100Mb LAN off one 48...

Re: Ethernet via SDIO

I don't see why hanging 2 x 100M LAN9514 Wthernet controllers off a 480M bus is a problem, from what I've seen SDIO won't be any better.

The chips have an MTT USB controllers built in so USB bus contention isn't an issue

There's been a few changes since the CM1 Notably the device tree file for the CM1 is not compatible with the CM3, your best tack here is to get the source for the latest device tree file, add in your custom bits in and re-compile.
