Hi-
After reading the official procedure from Raspberry Pi on flashing the compute Module 3 / 3+ eMMC on-board storage with Raspbian, I thought: There has got to be a less convoluted process.
And I found one. It's documented at the below link:
https://raspberrypi.stackexchange.com/ ... module-3-3
Hope it saves folks time & grief and gets them developing their solutions on a Compute Module more quickly- T

Thanks for the heads up, might add something like that to the docs.

May also want to mention in the docs that if you have a normal Pi running Raspbian, you can also just connect the CM board by USB and select the second option from the following pop-up screen you will get:
Can then dd your image to the new drive that will appear.

While we're at it, here's a problem I hit yesterday with a CM1 and its solution.
Despite having the drivers etc installed windows 10 wouldn't recognised the CM when connected. The solution was to boot it in mass storage mode from a Pi then, while leaving the I/O board powered move the USB slave connection from the host Pi to the windows PC.
Windows then recognised it as mass storage device.

@incognitum: That looks very elegant too: I hadn't tried that!
The documentation really does need to be updated to reflect the alternate- more elegant- ways of populating a Compute Module with an OS. The official method is unnecessarily complex & time consuming. Folks just want to get on with prototyping their solutions, not spending an age configuring their development environment.

Re: Easier way to Flash Compute Module 3 / 3+
Hi there,
i was wondering for a project i'm starting to consider, if there is a way to flash and clone multiple compute module 3... i'm not very good with rasberry and i'm starting to study but in the project i'll have 1 master compute module 3 and several module that need to get all the info from the master.
is there a way to speed up the process? is there an hardware to be acquired to do that? can someone help because i saw a cluster hardware to fit 7 module but i don't know if it works as a single node or can be used to speed up the process...
please help defining the process.
thank you so much,
Davide.

Re: Easier way to Flash Compute Module 3 / 3+
ive been wondering if the usbboot could be made part of the official rpi SD imager tool
it would then detect the CM, shove over a bootcode.bin+msd.elf, and then allow flashing a .img to it like it already does with SD cards

Re: Easier way to Flash Compute Module 3 / 3+
If you mean the Turing Pi then I'm not sure it would help you program CM but if you use one or more of either the official CM I/O board or my ClusterCTRL Single/Triple (I'd assume there are others too) then you could setup rpiboot to get them as MSD and then trigger writing the image with a udev rule or script something similar prompting you to switch CM when done etc.dadonelmondo wrote: is there a way to speed up the process? is there an hardware to be acquired to do that? can someone help because i saw a cluster hardware to fit 7 module but i don't know if it works as a single node or can be used to speed up the process...
