Hi, I have just tried to upgrade all my stuff to the MF 4.2 and I cannot seem to get my PC to recognize my cerberus board. I did a complete erase and install of the boot loader using STDFU tester, and everythign said “success” but when I reboot or reset the board it does not show up in the devices tab. I have tried a reboot, and tried uninstalling and reinstalling the USB drivers and no change. The only way it is ever recognized is when I jumper the boot pins. I am at a loss…
Thanks Gus, the machine is 64 bit windows 7, not USB3. Before the upgrade I was able to program my Hydra without problem. If I plug in my Hydra it shows up in devices, but the Cerberus doesn’t.
Try using a Powered USB Hub and please make sure you feed it with a really good 5V source with High Amp…
I’ve learned that even using a USB hub with cheap power supply can give you grief…
here is the Power Adapter I’m using with my USB Hub, I haven’t had an issue ever since… while before using that I was constantly having issues with deploy and all kinds of weird behavior…
cheers.
if my calculations are right I think the Adapter below puts out 400 to 500 mA right?
@ Jay Jay, you can power a hub with an appropriate supply. A proper powered hub has internal power regulation which means you’d typically need 6.5v minimum to guarantee stable 5v out. Appropriate means whatever is within tolerance for that particular hub; I’ve seen one (admittedly massive, 10 ports or something) that came with a 15v 1a supply.
Make sure when you update the board you follow the erase step. The board must be erased prior to the Tinybooter being updated. To perform the erase step press the “Create from Map” button then select the Erase radio button then press the “Go” button. After this follow the remaining steps as before. The Erase step is easy to overlook. The erase step tends to be the most overlooked step users face when updating the Cerb-Family of boards.
Do you have your windows update to search for drivers? Another person on the forum was having a similar problem with Hydra’s on-chip program. Here is a link to the forum post that may be of some use: http://www.tinyclr.com/forum/topic?id=10466&page=5
His reply is on page 5 but the main question is a few post back from the reply.
