Re: CM3 eMMC override?

Hi. What is the use case you are trying to deal with?

In general, if an end user was to replace the compute module within a product it is unlikely to directly work (e.g. because the on-board eMMC is blank), so why do you think the end user would try this?

Re: CM3/CM3L boot modes

Yes I believe if I wanted ethernet boot I would have to use the LAN9514 family for it to work.

Is that OTP flag settable post-manufacture?

CM3/CM3L boot modes

Reading through the new datasheet for the CM3 & CM3L I see mention no mention of alternative boot modes (i.e. non-eMMC/SD and USB host). As they are using the newer SoC should they also support USB mass storage & ethernet boot (if using the correct USB ethernet chip)?

Re: unique number

I think what Dougie is trying to say is that the MAC address because it is generated from the serial number is no more unique than the serial number is.

Re: Connect internet with CM

The Compute Module isn't designed to be used "off the shelf" instead it is designed to be used within a custom designed host board. That host board has access to things like the USB interface from the CM, so that can be used as well as things like the serial connection for WiFi, GSM, Ethernet or wha...

Re: CE compliant information

CE doesn't just apply to electrical parts of a product, but shows that all European products rules are being complied with. So if a RPI was embedded within a toy the CE mark would not only indicate the electrical safety aspects & radio interference aspects but also adherence to the Toy Safety Direct...

Re: Breakout board

Be cautious of the compute module. Broadcom has an agreement with the Raspberry PI foundation, but may not deal directly in limited quantities to individuals, kickstarts, or small enterprises. You may need to order a couple of thousand modules ! Availability might be tight. This has happened before...

I would have though most users of the CM would be using a custom Linux with their own software, etc. (e.g. based on buildroot) rather than expecting users to install their own distro of choice?

The image file contains a formatted Linux filesystem within partitions so there is no need to create partitions or format any of them - they will just be overwritten each time you do the dd command.

Re: Wonder about jack audio

I think it would depend on how the headset pins are connected. My understanding is that most have the tip & the first ring as stereo audio, but then differ on the other two rings (mic & ground in opposite orders). The B+ puts ground on the 2nd ring and the video on the 3rd/sleeve, so if the headset ...

Re: Getting the Compute Module to work

They are talking about the computer you are using to program the module rather than the module itself.

RPI machines (of all types) don't have a BIOS, but your desktop will and may need settings changing to allow the USB programming of a module to work correctly.

Re: Can we use a usb stick to Flash eMMC

Unlike a standard PC the rpi doesn't have a BIOS/bootloader which gives you the option to do a PXE boot or from an external mass storage device (i.e. USB stick). The only options are either the internal eMMC or if you set the correct state for one of the ports it will allow you to force the CM into ...
