Hi i get this message in the initial startupscreen when i have a SD-card inserted:

 

cat: cant open `/sys/block/mmc/removable` : No such file or directory

sh: bad number

cat: cant open `/sys/block/mmc/device/model` : No such file or directory

 

When i tested Openatv with  SD-card inserted there were no errors.... But i like Openpli and i just prefer to use it.

 

all is working but it is possible to get rid of this error message in the startupscreen or maybe some other setting i can do.

I hope someone has a solution.

The above quoted enigma2 log is from the H5 OpenATv image. So the same error is listed in both images. The only difference is you do not see it in the ATV image start-up or boot screen.

 

IMO, this is no big deal unless you want it to be. It would be nice if the little disk could be named and have a model number, then these errors would not exist?

Attached is a screenshot of the error message. This message is visible on my Zgemma for a second or two. This error is not hurting the function of the sd card and exists in both images.

Two completely different set of error messages.

 

The OpenATV messages shouldn't be visible in OpenPLi, our Harddisk.py catches these exceptions. The messages in your OpenPLi boot screen are from the mdev mounter (https://github.com/O...ev-mount.sh#L60).

 

Can you dump the directory contents of /sys/block/mmc and post that here?

[Taapat]

The problem is in the fact that is used $DEVBASE, which is only the first three characters from the $MDEV: https://github.com/O...ev-mount.sh#L22

 

Of course, the /sys/block/mmc does not exist, exist mmcblk0:

I think that everywhere in mdev-mount.sh need change /sys/block/${DEVBASE} to the /sys/block/${MDEV}.

@Taapat,

 

makes sense, but that change is above my paygrade I'm afraid.

[el bandido]

That file I posted is the wrong image!
 Will post the correct file in a few minutes.

[el bandido]

This is the correct one.

I think the result for the H5 will be the same as for the H3, which Taapat posted.

 

edit: yeah, looks like a bug in the mount-script.

DEVBASE build is assuming that we are using the [hs]d[a-z] devices.

Now that's is no longer true. I think that we need to review the DEVBASE construction algorithm.

[WanWizard]

Job for MiLo?

[Taapat]

Why, I think for all of us .

[Dimitrij]

	def getUserfriendlyDeviceName(self, dev, phys):
		dev, part = self.splitDeviceName(dev)
		description = _("External Storage %s") % dev
		try:
			description = readFile("/sys" + phys + "/model")
-		except IOError, s:
-			print "couldn't read model: ", s
+		except:
+			pass

[Taapat]

No, here we need exactly the same fix in the splitDeviceName to properly get dev and part: https://github.com/O...arddisk.py#L814

Fixed? i think so.
No longer see the error message at boot.

Now able to format sd card as hard drive. Could not do this before!

Thanks! EB
