DLPC3437: What does FPGA keying failed mean?

Jason Chang51

Part Number: DLPC3437

I read FPGA status via composer and find FPGA keying(register 6Fh) failed. I checked DLPC3437 software programming guide and there is no description for this. What does FPGA keying failed mean? What I should do to fix this issue? I attached DLPC3437 software programming guide. Thanks.

Hi Jason,

FPGA Keying failed means FPGA handshaking protocol fails in bootup process. Please check you are using the correct FPGA binary and respective DLPC firmware.

Could you please let us know, are you using the TI.com EVM or your own designed board. If you are using your own designed board, are you using the same FPGA part suggested by TI.

Thanks,

Navneet
