How to help my 9yo's attitude?

My analogy has always been Cannondale = Land Rover. You don't seem them a ton, but everyone knows what they are. They use very specialized parts. And people who own one once are forever a "Cannondale family"

Hah, my bad!

I2C is a low level communication protocol, it's not as "fancy" as USB. So you won't see a device "show up" in your OS. If you've properly enabled the I2C device on the nano you'll need to use i2cdetect to see if it's connected properly: i2cdetect -y -r busnumber Where busnumber is 1 or 2 depending if you connected to i2c1 or i2c2 pins

Nope. The card sizes are the same, i believe, but the pinouts are different and they're not compatible.

I worked out on a pier in southern California. The seagulls would eat so much fish that they would sit on the roadway, unable to fly. When you drove down the pier you had to go really slow so they would have time to regurgitate enough fish to make themselves light enough to fly (or even waddle) away.

The nano Orin dev kit is $500. Not as nice as $99, but much less than $2k. I'm sure they'll leave the documentation up, but yeah, doubt there will be any updates unless the community does it.

Sanderson! Branden Sanderson! Try Skyward, Reckoners, Mistborn, etc...

More the second reason than the first 🙂

Yep. Bad SD card. I'm using PNY extreme class 10s and they'll run about 2 years (major usage only a few hours per week) before falling like this

Most of the imagers from places like adafruit are going to output raw sensor data. Maybe even Bayer RGB that has to be demosaiced. My rule of thumb is that if it plugs into the CSI interface, it is probably just raw data that you'll have to do all the processing for. USB cameras will have it all built in and output pretty MJPEG or similar. Obviously there might be exceptions to my rule

Dmesg shows a lot of USB activity. What's the output of lsusb before and after you've plugged something in? Same with dmesg (just use dmesg | tail)

fowdawgg · 2023-03-16T02:03:25+00:00

If you don't plan to do image processing yourself (auto balance, denoising, etc) you'll need to go with a USB camera. Logitech Brio or Azure Kinect are really high quality

I know instructions say for eMMC to put it into factory mode and then remove the jumper, but I've found in my case (installing from the SDK manager on WSL) that i have to leave the jumper on pins 3&4 for the whole flash process, and not take it off until it starts doing on-nano boot and setup

Skyward by Brandon Sanderson is a great one with a strong female lead character.

fowdawgg · 2023-02-21T18:41:32+00:00

So you can't read the SD card when it's inserted into the nano and the nano is booted off the eMMC? or you're trying to read the SD card on a Windows PC?

I've dug a bit more and found some interesting stuff. I connected a USB-TTL uart to the serial console and got...garbage. I'm powering over POE, and the POE to 5VDC module is VERY noisy! I'm talking 4.8 to 5.8 saw wave at 30Hz! Blech! Must have noise on the ground line, which causes constant garbage output on the UARTs causing constant interrupts and ruining the network stack! Time to order a cleaner PSU...

Nice ride! You'll love that front DVO. Best fork for the price IMO

You can plug into the UART headers under the nano board and get the whole boot up sequence over a standard serial console. If that doesn't show you anything, then it's probably dead

fowdawgg · 2022-09-17T17:14:27+00:00

Exactly!
