Regular ContributorHi,
1) Keep tweaking the programmer settings and trying to flash the memory?
It looks like the FPGA is not able to communicate with the Flash. The device ID is for the flash
2) Order brand new flash chip, replace it and hope that it should work properly?
It might not help. It will depend on what type of damage.
3) Order brand new FPGA chip together with flash chip and replace them both?
This might be an option but it will not be cheap.
4) Any other option?
May I know how do you connect the Arduino to FPGA. I would like to understand the connection to determine what might be damaged.
May I know if you still need to use the FPGA with the flash?
Thanks.
New ContributorI will provide some pictures of arduino and FPGA. Thats the best way to explain how did I try to connect one to another. On the other hand. I used the arduino Uno headers on the FPGA just like one would use to connect standard arduino uno shield, except I used arduino itself.
At some point flash memory usage is inevitable in my application. I need to preserve the FPGA code after power off.
