After 3-4 days don’t power up on the card, this problem is happened when plugging Ethernet cable, I use USP DP, I have readed the topic My Spider Gadgeteer is not stable at https://www.ghielectronics.com/community/forum/topic?id=12191 but I don’t think the power is the original problem because my project runs fine 1 week ago. I have to make a demonstration soon. I’m very frustrated :((. Pls help - me !.

please tell us about what power supply you’re using with the DP module.
I’d suggest disconnecting modules individually and try at each point. I assume you mean that if you don’t have the Ethernet cable connected at startup, this problem doesn’t show?
[quote]@ Brett -So really, you’re just using USB power? Running a display on that is asking for trouble.
So what has changed since then? Code ? New cables ? Different PC? Different USB port ? [/quote]
I try every things, but it 's ok when I try to plug only one Ethernet J11D module in Spider board. Maybe it is a power problem like Gus said.
[quote]@ Gus - I bet it is a power problem even if it worked before. [/quote] How can i debug without USB cable ? :’(
and how can I resolve it using this USB client DP ?
@ hoavinh -
Hi,
I would try the following things:
Take a new Gadgeteer Cable between USB DP Module and Mainboard.
Remove all other modules including the display module.
Re-Deploy the mainboard firmware.
Deploy an “empty” application with no modules connected.
Connect the display cables and deploy an “empty” application.
Then connect the other modules and try your original application.
@ Mike - It’s great ! I see in Google there are many product, can you give me an example for USB hub product it’s worked fine with enough power. Can I take any USB hub ? Sorry for my bad experience about it
@ RoSchmi - I try your method but not run :’(, I hope too much but … Finally to check whether it is enough power ? I have to deploy without using debug mode, unplugging usb cable and then using an external power 12V, that works fine now.
So how to resolve definitively this problem ? Some one has solution ?
@ Mike - If buying a usb Hub on which I plug USB Client DP, that is enough power ? 5V will provide the later ? or 12V ?
