I’ve buy a UberBoard V2, LPC2148.
I try to use microSD with FW.SFE to do bootloader, but windows not detect storage device, and i cannot test my own applications…
The Test aplication included in basic firmware works correctly with hyperterminal…
Who use usb bootloader with this board?? not is automatically preinstalled??
Thanks in advance.
P.S: Sorry for my poor english.
I’m having similar problems. I have the UberBoard V2, with the 1GB SD Card from SF. Every time I plug the board in (USB) XP pops up the “Device not recognized”.
Followed the tutorial step by step and still no luck, any suggestions?
-thanks
See here:
Could it be that all the Uberboard V2’s that SFE has sold are faulty and don’t work with the provided code??
Is there anyone out there that was able to step through the tutorial and get the UberBoard V2 working?
I believe you can solder a pull-up resistor from the D+ line on the USB to the Vbus line on USB and the problem will be taken care of.
Tried a 1k between D+ and USB Vcc and still no luck, any other suggestions?

It is supposed to be 1.5k between D+ (for a full or high speed device) and 3.3v (which Vcc just happens to be on this board).
Beyond that, I don’t know. I’m a USB guy, not an LPC or Uberboard guy. Judging from that other thread, though, it seems like pretty much exactly the same deal as with SAM7S chips. There is no pullup at all on the schematic. I don’t know how they could have ever expected it to work. I think that some USB chips have a switched pullup built in, but the aforementioned thread seems to indicate that this isn’t one of them.
Even if you do get it to work with a permanent pullup like that, there is a potential problem related to the controller not being able to disable the pullup at certain times, since you’re tying it permanently high.
