CMOD A7 Quad SPI Flash Program Fail - won't program again

[JXS]

Hello 

 

I tried to program my CMOD A7 through quad spi flash. Somehow the process failed (sorry that I didn't get a screenshot). When I power cycle my FPGA and PC, I can't detect hardware server in Vivado. 

 

Does this mean my A7 is bricked? Is there a way to keep using it?

 

Thank you

I power cycled PC/FPGA a few times and finally got hw_server back.

I encountered this error in quad spi flash write. any idea what is wrong?

 

Thank you

Hi @JXS,

The bests solution that I can offer would be to use a different/better quality usb cable; there is a collection of other threads on this particular topic with the Cmod A7 on this thread here:

Thank you for your very prompt response. I changed the cable and was able to program it properly.
