Cyclic USB connection

[zaxtone]

Hello. Burned chip U6 SPARTANXC3S100E, also burned U10 FTDI FT245RL.
I replaced it with new ones.
Made the FTDI firmware as specified here
Now the computer sees KFLOP but in the program it tries to connect cyclically

Hi zaxtone,

Have you tried performing Flash Recovery?

Hi zaxtone,

It seems other things on the board have also been damaged. Possibly outputs from the DSP used to enable and reset the FTDI chip. Or possibly a regulator (1.2V, 2.5V, 3.3V). I can't tell from your video if the board is resetting. You might try using an external 5V supply in the unlikely case that USB 5V isn't supplying enough current.

Sorry it isn't normally cost effective to attempt repair of these boards.

After the U6 was burned and U10 was first replaced with U10, the connection was, but U6 did not all the axes work and some messed up.
Then I changed U6 to a new one. Now I have this problem.

Hi zaxtone,

That would somewhat indicate that the replaced U6 (XC3S100E-4TQG144C) was bad or not installed correctly. The USB data passes through that device. Did you check carefully for bad solder connections or solder shorts?

In addition, all the conclusions were lost, stopped blinking. Now there are such messages

Hi zaxtone,

I don't understand. Those messages are different. What did you do differently?

They indicate the hardware is all working correctly. You only need to Flash the New Version.

Regarding your Private Message we are in Pacific Standard Time (California).

Is it possible to send a new board without elements.
I would reinstall them to a new one
I suspect that internal conductors could be damaged

Hi zaxtone,

I'm not sure I understand. But no, we don't sell bare boards without components.

Hi zaxtone,

Congratulations
