Glad Pi Shop got it sorted for you! That is stellar service!

No _you're_ the best!

@@JeffGeerling yes I'm , cause I watch your channel

It gets easier the 50th time you do it :D

Do you live in mexico?

I have a blog post just for you! www.jeffgeerling.com/blog/2020/usb-20-ports-not-working-on-compute-module-4-check-your-overlays

@@JeffGeerling Excellent!!! Thx you 🙂

@@JeffGeerling Hi, man! Thanx for all your videos and so simple instructions! I'm lame at all this RPi stuff yet, so I'll ask few silly questions: If my CM4 has a built-in eMMC then does it means that using an SD card is useless inside CM4IO + CM4 eMMC setup? Will I be able to make a dual-boot on eMMC? I have the max. of 32 Gb eMMC. It seems that was a right choice. P.S. I've blamed myself few times that I've didn't bought a simple Raspberry Pi 4B+ instead of this combo! :)) Firstly I've got a very stiff sockets combination between them so I've got few silver hairs when finding a way to install this CM4 into CM4IO. And now I understand that I've ordered this combo because "wow, eMMC and SD Card and full size HDMI ports for practically the same price as Rpi 4B+!" :D Now I think that the only good reason to have it is that it has a big board and probably this will make it less hot. I've bought Waveshare's USB3.1 Hub and I guess now that I will have only USB 2.0 speeds out of it. Another silly question: what if eMMC will become corrupted? Is it basically the same memory as in SD Card or much more "long-life"?

I can't wait either!

Good point... I think I must've just run through it at a point where that was the recommended version, and I've never updated my notes since!

I like 4GB RAM and 16 GB eMMC as a sweet spot. Only get more if you know you'll need it.

No, unfortunately they don't quite work that way (though it would be pretty awesome!).

Same here. Is there a way to update EEPROM just from CM4 itself, like on usual RP board, or does it involve rpiboot and flashing again? Confusing...

This would be super helpful =

Ok ChatGPT says yes. This makes perfect sense, I just wanted to be sure.

Unfortunately that's now how the clustering of multiple Pis work-you can run a workload across Pis if it can be split up, but adding Pis to each other doesn't combine all their CPU, RAM, and GPU together so it can be used like one big unit.

Oops, in fact i have forgot to unplug the micro usb connector. It's fine now !

Suppliers are supposed to be getting them in stock, but from the ones I know, they said they are starting to see Compute Modules in stock, but no IO boards currently :(

as in you rip out the old motherboard and replace it with a custom pcb ? maybe look for the the design files for the cm4 dev-board and remove any hardware you would not need.

@@jyvben1520 yup i am looking at all the pin outs and chips i need for lcd , keyboard , trackpad , battery and usb ports .. + i will keep the pci 1x slot in form of m.2 so i can just remove the ram hatch and connect a m.2 to pcie board and use the 1x slot for experiments . i will reuse the existing cpu cooler and battery & it will take a lot of prototyping . i will first get the laptop keyboard , trackpad , lcd and battery working before implementing rpi compute module .

I think the best option could be like an IO Crest board like amzn.to/43gAZFE with two ports - that is, if you want SATA. For dual NVMe, it's a little harder. There are a few boards that split a single PCIe lane into two or four, but those kind of boards can get a bit pricey.

@@JeffGeerling Thanks Jeff. Yea, that really is the rub eh.. splitting the lane...I suppose. And...I'm doing this with no particular need. Not even making the "check out what I just got working" videos like you...lol. which...we all enjoy and appreciate. I've got OMV installed on the new CM4 on the Raspi IO board. Kinda cool seeing how fast the thing boots to Bullseye or OMVs Debian. Seems even faster than an SSD to USB 3 on the Raspi 4B. Guess that makes sense. I can always run two OMV servers. I have like 50+ devices on the network with all the Home Assistant IoT stuff...what another server lol. Use a 2TB SSD on the new OMV and have like 4TB slower access storage on my existing OMV. PEOPLE...if you need SSDs or have a future project in mind...it's a buyers market! Seems they are the one thing manufacturers have an overstock of and they are super cheap! Like 2TB Western Digital for under $120. Can find slower cheaper 2TB for under $85 on Amazon. Crazy! Thanks Jeff!

It's a special character in my PS1: github.com/geerlingguy/dotfiles/blob/master/.zshrc#L16  (Shift + Option + K on a Mac).

Hi! Was this problem caused by a power failure fixed? Sorry if I'm touching a painful topic!

wut

I'm still doing all these videos with pre-production units... I ordered two more on launch day, and am still waiting for them (no ship date yet on my order at the Pi Hut).

Unfortunately no, as the eemc on the pi compute module is non removable.

If its a "pitray" make sure the "boot emmc" switch is in the ON position if booting from a microSD card or eMMC and the OFF position if trying to flash the onboard eMMC... It makes no sense but its the opposite of what you would think it would be.

You can't use the micro SD slot and eMMC at the same time. The micro SD slot is only intended for use with the CM4 lite versions. However, starting from a USB drive should work, and flashing the eMMC maybe also.

@@R4C3R I wasn't aware of that limitation, sorry. But for USB to work the emmc needs to be clean otherwise it will boot. In theory one could create a boot image for usb that after installing the OS automatically changes the boot order so that later installs work. But that's probably more work than what it saves.

You'll need to do this: www.jeffgeerling.com/blog/2020/usb-20-ports-not-working-on-compute-module-4-check-your-overlays And it has to be in the boot/config.txt file when you mount the eMMC onto another computer like your Windows 10 computer.

@@JeffGeerling Hi Jeff. I am not seeing the boot/config.text file on my Windows computer when I mount the eMMC. Sorry for all of this. I am a newbie to Raspberry Pi. There is no boot folder on the mounted eMMC disk

Heh, multiple a computers and multiple io boards! I think there was some volume flashing utility or setup mentioned in the Pi forums once, though.

@@JeffGeerling so a fleet of flashed compute modules running PI OS or Windows 11 it is I guess

@@JeffGeerling figured it out. There’s two pins ( on the carrier board ) that if jumped tells the computer it’s just an sd card. Then you can use balena etcher to flash them all at once. Now to remix the open source carrier board so I can daisy chain them with the usb c; basically make a usb c hub/ carrier board.

There are two camera connectors exposed on the CM4IO board.

@@JeffGeerling Yeah, i know. I’m just dropping a hint, that setting it up should be your next vid ;)

It would be really nice if it were just a little GUI app that worked like the Pi Imager. Open it up, plug in the CM, click 'mount' or whatever.

Ha! They'll return. I only had one little gaffe in this one, surprisingly, but I don't feel like a 3 minute video does the bloopers justice.

also not working on a regular MacBook. `make` results in an error

It's useful advice regardless of whether you can get the modules. Pretty much all recently released tech items are difficult to get, whether they be Pi Compute Modules, graphics cards, CPUs or games consoles. None of that is Jeff's fault!

Right? There were like 3 module configs that were gonna be the bulk of the orders. They could have prioritized production of those first.

I'm trying to put out a bunch of content so that when people finally do get theirs (I'm still doing all this with a preproduction copy... waiting for my order from The Pi Hut still!), they'll be able to get up and running quickly and learn from my mistakes.

@@johnm2012 Not blaming Jeff. Blaming the Hype Machine. Jeff consistently produces excellent content. It's just frustrating when I go to burn plastic and find that I am thwarted by Covidiocy and supply chain throttling.

@@JeffGeerling Calm thyself Kimosabe. Your work is not in question. I too suffer from slow delivery from Pishop, PiHut, Canakit, Sparkfun and Amazon. Frustration #Over9000 !

@@TechyGuy17 maybe not, might just split your tv ... free double vision ... ;-)

@@jyvben1520 That would be cool tho, hope he signs one of the halves xD

Did you ever fix this problem? I've got the same issue

My mistake -- missed the 1.0-0-dev. Sorry. End of a long frustrating day.

The eMMC flashing occurs over a USB 2.0 connection, so it's limited to a maximum of 35 MB/sec or so. If you flash a modern (good) microSD card over a newer USB 3.0 card reader, you can get 3-4x faster speeds (or even more in rare cases).

@@JeffGeerling Thanks for the reply. My flash speed is limited to 4-5 MB/sec on different linux and windows computers. I'm not expecting the max USB 2.0 speed, but I was hoping for more. It seems that the Pi team put a limit on the flash speed. www.raspberrypi.org/forums/viewtopic.php?t=307347
