1  Hardware and U-Boot firmware / Hardware / Re: Is my sheevaplug dead ??? on: February 17, 2010, 01:03:53 PM
I'm trying to communicate with Globalscale for a RMA but they are just not responding. Seriously, this one month warranty is really a scam !!!

In Quebec (Canada), I could use the "legal warranty" which states that a product should last a "reasonable" amount of time (generally, at least one year). However, since, it is a U.S. product, I don't know if I can use this. Is there something similar in the U.S.

I mean isn't there anything we can do to just get a replacement Huh

I'd like to buy the guruplug (sheevaplug2) but what's the point if it won't even last a year

Cheesy

Thanks superpat for that quick and enlightening reply.

Again, thanks for your support. It helps me accept the death of my plug ...

$ sudo aptitude install libftdi1

Good point! I did that. But it still complains about the missing library. My guess is that it is searching for this library on the plug.
Code:
$ locate libftdi.so
/usr/lib/libftdi.so.1

$ sudo php ./runme.php nand
...
 ****   Burning uboot and environment variables ... This will take few minutes ...
openocd/openocd: error while loading shared libraries: libftdi.so.1: cannot open shared object file: No such file or directory
 ****   openocd FAILED
 ****   Is the mini USB cable connected?
 ****   Try powering down, then replugging the Sheevaplug

Also, plugging and unplugging the mini USB doesn't bring up any message in dmesg.

I think you are right. The brown stuff is probably elastomer to hold the components down. However it looks pretty much cooked Wink But I don't understand, you are saying you do or you don't have any elastomer on yours ? In any cases, the power supply still gives me an unstable 3v and putting a load of 10 ohm on it will clamp the output to 0v.

According to my 120v ac, it is pretty much stable and the ambient temperature is room (~23 C). I did piled the plug with my modem, router and external hard drive once. The temperature of this beautiful electronic pyramid climbed relatively high (~60 C). But, this was several months ago and since, I don't pile them anymore. It think that the power supply failure is more related to the USB power overload.

First, thanks for your replies Smiley

Second... I think my power supply is dead :S
(see attached picture). There seems to be melted stuff all over the place... Is this normal ? ? ?
I can't figure out which component melted and how could it spread like this. I wish I could find a picture of the power supply on the web...
I also measured the voltage with a multimeter and only got something really unstable, oscillating between 0V and 3V.

Trying to reinstall via the sheevaplug installer gave me this :
Code:
...
uboot/uboot-env/fw_setenv recover3 usb start\; fatload usb 0 0x00800000 uImage\; fatload usb 0 0x01100000 initrd

 ****   Burning uboot and environment variables ... This will take few minutes ...
openocd/openocd: error while loading shared libraries: libftdi.so.1: cannot open shared object file: No such file or directory
 ****   openocd FAILED
 ****   Is the mini USB cable connected?
 ****   Try powering down, then replugging the Sheevaplug

what ever I tried, I can't get the serial communication.

So ... here is my advice. Don't plug too many unpowered usb devices on the sheevaplug Wink

I'll try to change the power supply ... any advices ?

Hi my sheevaplug suddenly stopped working. I think that I somehow messed up the file system. I would like to reinstall it but, I can't communicate with the serial communication.

Everything I tried doesn't bring up /dev/ttyUSB0 (Ubuntu 9.10, 2.6.31-19-generic, x86_64)
Code:
modprobe ftdi_sio vendor=0x9e88 product=0x9e8f

Code:
$ cat /etc/udev/rules.d/85-sheevaplug.rules
# udev configuration for sheeva plug
ACTION=="add", DRIVER!="?*", SUBSYSTEM=="usb", ATTRS{idVendor}=="9e88", ATTRS{idProduct}=="9e8f", RUN+="/sbin/modprobe ftdi_sio vendor=0x9e88 product=0x9e8f"

Also when powering up the sheevaplug, the only thing I get, is the green led quickly blinking once per second (in synchronization with the rj45 leds). Does this mean it is dead ??

Can I have any hope ??


Edit:
The power supply is dead. Changing it for a good 5V 3A switching power supply solves the problem (~15$). 2A should do the trick but I suggest a 3A to avoid all problems.
