Hello,
I am having a similar problem to the one mentioned originally (USB disk recognized initially, but freezes up when downloading new program).
Was the problem ever resolved?
Like Serge, the machine in question is also a Lenovo laptop, but an E520 model - has Intel 6 Series/C200 Chipset Family USB Enhanced Host Controller. OS is Windows 7 Home Premium.
I have not tried any of the various "tricks" to get it working on my Lenovo, because I also have a desktop PC that works fine, so I can recover the filesystem by connecting to that machine.
I have recently upgraded the desktop PC to Windows 7 Home Premium (previously running Vista), but interestingly it doesn't seem to have a problem with the mbed filesystem like the Lenovo does. For reference, the desktop PC has an Intel ICH8 Family USB Universal Host Controller.
Another clue (but perhaps not very helpful) is that if I wait long enough for the file copy operation it will eventually time out and pop up a message box with I/O device error 0x8007045D.
I see another forum topic that looks similar here http://mbed.org/forum/helloworld/topic/1722 including once comment about another user with a Lenovo, so perhaps this is a clue? In my case however it doesn't seem to have anything to do with the choice of browser, because I'm just copying a .bin file from my hard drive to the mbed using explorer, and it still freezes up.
Would be keen to hear if a fix was ever identified for this issue - would be nice to be able to use my mbed with the Laptop rather than being tethered to a desktop PC...
Cheers
Andrew
Hi Guys,
I seem to have an annoying problem working with my Mbed.
It seems that the mbed drive on my Windows7 machine is freezing when I try to upload a new program. The way I usually resolve this is disconnecting the Mbed and reconnecting it while holding down the reset button. When I try that a couple of times I can format the drive and upload my new program.
This is very annoying, as I loose my serial line when disconnecting the mbed.
I have tried another Mbed, but with same results.
What am I doing wrong?
Kind regards
Jesper
