Pprogramming FPGA

Jump to solution

Hi,

1.We are trying to program our custom board (XC7Z014clg484 -2) , once we connect the hardware, JTAG detects a hardware device of speed -1(i.eXC7Z014clg484 -1) which is not our custom board, eventhough we choose the correct custom board part number .

2. Later, If we program the device, it shows error like "  program_hw_devices' failed due to earlier errors "  , we checked all the components regarding Fpga its getting proper voltage, we even tried changing cables. 

3.We created a code with  speed -1(i.e XC7Z014clg484 ), where the JTAG detected hardware with speed -1 ,we dumped it worked first time but when we reprogram 3-4 times it failed with above mentioned error.

Hi,

Check if you have a correct read from the XADC( i.e. the temperature value of the FPGA). This issue happens to me. Was a problem in the PCB layout of the board. 

If you have another board , check if you have the same issue.

When ever you get 'failed due to earlier errors' error, the better approach is to redesign your whole project.

Is the part traceable?
