Today I had a strange trouble after adding this line to a very small Gadgeteer project:
display_N18.SimpleGraphics.DisplayImage(Resources.GetBitmap(Resources.BitmapResources.PriceScreen), 0, 0);
The Hydra continues to reboot and therefore I can’t be able to connect to the mainbord for erasing the application.
I tried to reset the Hydra, I also tried to power it with an external USB power supply… but nothing changed.
Then, I assumed that I may had damaged the Hydra with some ESD and I tried with another new Hydra, but the problem happened even with the new mainboard.
Therefore, I tried to reload the firmware following the instructions in:
- Grounded pin 8;
- turned on the Hydra;
- removed the pin connection
and the Hydra was recognized as “GPS camera detect (COM10)”
Unfortunately my project is in VS2010 - NETMF 4.2 (for legacy reasons), but anyway, I have found the Loader in
Program Files (x86)\GHI Electronics\GHI OSHW NETMF v4.2 SDK\FEZ Hydra\Firmware\FEZ Hydra TinyBooter Updater
Running the UpdateFEZHydra.bat as Admin, it shows the error: “SAM-BA_cdc” is not recognized as an internal or external command…
then I added the line
[em]cd C:\Program Files (x86)\GHI Electronics\GHI OSHW NETMF v4.2 SDK\FEZ Hydra\Firmware\FEZ Hydra TinyBooter Updater[/em]
to the .bat.
Running the modified UpdateFEZHydra.bat as Admin, the result was:
-I- Waiting …
-I- TCL platform : Windows NT
-I- SAM-BA CDC 2.10 on : windows
-I- Retrieved arguments from command line :
-I- argv 0 : at91sam9rl64-ek
-I- argv 1 : TinyBooterLoader.tcl
-I- argv 2 :
-E- Connection at91sam9rl64-ek not found
-E- Connection list : com10
the only reference to at91sam9rl64-ek is a sub-subfolder:
that contains 2 files:
Now, the questions are 2:
- I’m wandering around chasing butterflies or this maybe the right way to resolve the “root” problem?
- If the firmware “reload” maybe the right choice, I have done some mistakes for the 4.2 firmware upload? (The Loader update procedure for 4.2 seems to be no longer available from Hydra resource page)
Really thanks in advance for any help and sorry for the very long post… :-/
Have a good day!
