Compute module not talking

[svrsig]

I cannot get the Compute module (in its IO board) to listen properly.

The documentation is quite poor and gives no hints about troubleshooting. I don't have to reboot the Compute module to get it to appear as a mass storage device do I?

Raspberry Pi is now a mass storage device, use lsblk to find it.

Hmmm, that's odd
I've just tried the same on my Pi (previously I'd only run rpiboot on my desktop PC) and I get

Code: Select all

$ lsblk

(I haven't expanded either rootfs yet, which is why mmcblk0p2 and sda2 only show up as only 2.7G)

What output do you get from dmesg ?

What output do you get from dmesg?

I hope it means more to you than me!

Have you got a separate (quality) power supply for each of your Raspberry Pi and Compute Module?
Are you using a USB hub or anything? (although in theory that shouldn't make any difference)

[ShiftPlusOne]

I've had similar problems with other devices when there wasn't enough power to go around, so that's definitely worth checking.

Note that once rpiboot has done its thing, you can plug the compute module into any other computer to continue, as long as you don't unplug the power.

[svrsig]

Have you got a separate (quality) power supply for each of your Raspberry Pi and Compute Module?

Tried another power supply, no difference.

I have had a small success using a different Windows machine booted into ubuntu 10 - I can see the Raspberr y mass stoage device, format the master boot record, partition it, copy files to it. Move it to another machine and the folder appears blank. Look at it from the Pi using lsblk and no device is listed. There seems to be read errors preventing it from being recognised. Sometimes the Windows format tool can see the FAT partition size, sometimes it is not recognised. SD formatter complains 'this drive is not supported' or 'cannot get device geometry.

I am convinced it is a hardware fault on the Compute/IO module.

[svrsig]

This does appear to be a hardware fault so Farnell are sending a replacement item.

Thanks for all the help in diagnosing this.

[AndrewS]

Let us know if the replacement works any better

[svrsig]

Let us know if the replacement works any better

The replacement works exactly as per the documentation. Boring.

That is (of course) RISC OS cannot see the EMMC memory yet. I have tried commenting out the 'init_emmc_clock=1000000' line in config.txt but still no joy. The Pico image works (can't see the SD card but it doesn't try to during start up), and CTRL-BREAK works (with the Pico image). However the RC12a image fails on restart (if you type CTRL-SHIFT-f12 then 'restsrt' the screen just stays blank).

Yay, that's good news then

Well, that's obviously up to the RISC OS developers to fix - if they think enough people will want to run RISC OS on the Compute Module for them to spend the effort 'fixing' it

[svrsig]

It is (at least) possible that RISC OS has some attraction for embedded devices. The changes to the source code to talk to the EMMC (rather than to an SD card) are likely to be trivial - any clues from the Linux community please?

I think the relevant source is here:

Seems to be a general bad hardware build...

Or if they would preload the flash they would see that some boards just don't work...

[AndrewS]

Your error messages are slightly different to the ones that svrsig was getting...
Also, I think the xhci messages mean that you've plugged it into a USB3 port? Guess it wouldn't hurt to try using a USB2 port instead? *shrug*

[davorin]

That's the only thing I have..besides Vmware on top of iMac with USB2.0 ports...and that doesn't work either (o;

If it's a generell problem with USB3 ports, then this should be mentioned somewhere in a Wiki or the installation guide...

[davorin]

Well...also directly under OSX it won't enumerate with USB2 ports:

[AndrewS]

Hmmm, just done some tests myself, and I also can't get rpiboot talking to the Compute Module over a USB3 port. But I'm still running Ubuntu 12.04 (kernel 3.2.0) so I dunno if that's just because of my old kernel using out-of-date USB3 drivers
It (rpiboot) also doesn't work if I plug the CM into a USB2 hub into a USB3 port.

However rpiboot and CM work just fine in a USB2 port, or in a USB2 hub connected to a USB2 port. And as http://www.raspberrypi.org/documentatio ... lashing.md mentions, you can also run rpiboot on a RaspberryPi (which obviously doesn't have USB3 ports!)

[davorin]

That would have been my next try...using a RPi B+ for that (o;

Saw in the dmesg log that it actually assigned /dev/sg0...maybe I was too quick issuing "lsblk"...

[AndrewS]

Hmm...takes ages to dd to the USB device...still ongoing...

Apparently eMMC is optimised for small random reads/writes (that an OS would typically do), so perhaps it's slower than SD cards for big contiguous reads/writes (that a digital camera and 'dd' would typically do) *shrug*

[davorin]

Stopped it now after 2 hours....trying now to "dd" from the Raspberry Pi itself...

[davorin]

Hmm...can't be installing onto eMMC takes more than 2 hours???

When it does work (and the replacement board works perfectly), the transfer speed to the CM as a mass storage device should be about 7Mbytes/sec. Hence 10 minutes to flash 4Gbytes. Two hours is (IMHO) a hardware fault.

With the faulty CM board in its IO module, I found that lsblk on a Pi would consistently not see the mass storage device but Ubunto10 on a desktop machine would see it but (sometimes, and on other machines very quickly) threw write errors after a few files had been copied. It also seemed that I could only get that far if I used a 5V 2A power supply for the CM/IO board rather than a 1A supply.

The faulty board was replaced by Farnell by return of post and a reply-paid label brought to my front door a few days later to RMA the faulty device. Very good service!

[davorin]

Strange that both boards show this hardware fault...

Now even crashes when using an RPi as host:
