The #M5Stack #Cardputer Zero seems like a great small emergency #Linux device. And at the Super Early Bird price of £66 it's a no-brainer. Will be interesting how the #ComputeModuleZero performs.
-
#M5Stack is switching it up a notch with the #CardputerZero (more like a Walletputer at this point) - their proven cardputer format but with a #RaspberryPi #ComputeModuleZero (#CM0) instead. And the thing will be compatible with their 100+ M5 modules. Comes with: 320x240 display, WiFi, Bluetooth, USB-Host socket (USB-A and USB-C!), 10/100M Ethernet, 3.5mm audio out, HDMI, speaker, mic, MicroSD, etc.
"Lite" version (as above) for $59, normal version (adds an 8MP camera, gyro+accelerometer, 32GB MicroSD) for $89. But only if you pre-register. (Retail prices are going to be $99 and $149, they say.)

It took a while (thanks to UPS) but my "CM0 NANO Single-Board Computer" has arrived in the UK (from Digikey https://www.digikey.co.uk/en/product-highlight/e/edatec/cm0-nano-single-board-computer ).

@rpimag I've been playing with the forbidden :raspberrypi: .
I populated my test CM0 carrier which only has USB-C for data/power and a couple of pins to control power/RPIBOOT. Using rpiboot it boots the kernel and mounts a root NFS filesystem over USB Gadget Ethernet just like the rest of the family 😁 .

I received another batch of 10 CM0 last week. Combining the results from all batches I'm seeing a 25% "failure to boot from eMMC" rate which is less than ideal 😭 .

The rpi-imager problem was a red herring, after switching to dd I still can't get a [non-mangled] CM0 dev board to boot.
With the CM0 dev board on the left I can enable RPIBOOT, apply power, run rpiboot, write an image/sync, remove power, disable RPIBOOT, apply power, LED turns on after a couple of seconds and it boots from the eMMC.
But following the same steps on the other board when powering up after disabling RPIBOOT the LED never turns on (it was on whilst writing the image) and it doesn't boot. Even writing the image from the working CM0 doesn't boot (reading back after a failed boot still has the original sha256sum).
Anyone have any pointers?

Continuing my CM0 fun from last night where I removed the module from the dev board, soldered it to my carrier, reflashed 64-bit Lite RPiOS and it didn't boot, no LED, nothing. Checked the schematic, PCB for shorts, voltages, etc. and couldn't find anything so took it off and put it back on the official dev board where it also no longer worked so I figured I'd killed it.
Another one arrived today and it looks like I've somehow got rpi-imager into a state where it writes, verifies and configures OK whilst shafting it enough not to boot 🤦 .

In free air the #CM0 looks to hold it's own thermally and doesn't throttle running stress, stuffed in a cardboard box it happily throttled as expected.

The "Chinese market" Raspberry Pi CM0 has made it to the UK 🥳 .
Still seems a strange product, even the URL on the box ( https://raspberrypi.com/products/cm0-dev ) doesn't work 🙄 .
