Picozed FMC carrier card with Picozed 7015 SOM is not working

nithinsteffy 3 months ago

Hi Team,

I've been working with Picozed FMC carrier card with Picozed 7015 SOM for the last few weeks, it was working fine.

Recently i found that the clock was not getting properly on the PCLK pin, which was allocated for clk_out in my vivado design

And now i'm unable to flash my code via JTAG , it was not detecting the board. Even the D3, D4 LEDs was not indicating any.

What may be the reason?

Give the board to board connectors a nice IP wash. See if that helps as well.

Hi Aswin,

I tried it, but the problem remains same. And also i can't find any short circuit or visible damage.

How to solve the problem?
