[Resolved] Elbert V2 - bricked (after half year of using it)

Hello,

after using Elbert V2 for almost half of year and succesfuly created many projects, yesterday I "bricked" this board.
I was experimenting with simple VGA Arcade game on it. I made a mistake in ucf (user constrained file) and wrongly mapped clock pin. After loading bin file with this game to Elbert it stopped been properly recognized as USB device in OS (I tried it in Windows10 and Linux).

There probably is issues with clock for PIC ucontroller. I tried to attache MISO pin of eeprom(pin 2 in U3 circuit) to GND during start of powering board, but without any result.

Neither in Linux Os nor Windows device is not recognized as proper USB device (the Elbert board).

Is any chance to turn Elbert to 'life' - if yes how to achive that.

Thanks in advance and regards

 

Hi,

Elbert is alive again. It is after little "brain surgery" - I broke path from PIC clock (connection beetwen crystal and C14) leading to FPGA clock.
After that Elbert was again seen by OS as a proper USB device, and I was able to program it with proper bin file (proper project).
After that I again joined broken path and Elbert is working properly - I checked it with few earlier proper projects.

All owners of Elbert V2 bewaare of making mistake with mapping clok pin of FPGA pin because you got into troubles like me.

Regards

 

Hello rohit,

I am also glad that I came away unscathed from that issue
