Discovery 2 power problem

[Andrzej]

 Do you have the whole pcb layout?

Hi @Andrzej

If you are looking for the board size, see the 3D models at the bottom of the page:

For troubleshooting:

For fixing information with some layouts:

Thanks for your help .After replacing the FT232HQ chip I get such an error.Is the description of these errors?

Hi @Andrzej

Probably other ICs on the device are damaged as well, like NC7SZ126 and/or the FPGA.

On software connection the FPGA done flag is verified through JTAG. This bit should be low but in your case it looks like it is read as high. The DptiIO communication fails since with ERC 2 the FPGA is not programmed but I don't see the cause of the following connection retry error of 3077.

You could try "Force programming" under right-click or Options in this Device Manager. This will skip the done flag verification and program the FPGA but this will probably also fail.

Thank you .
