I have a problem with programming CY8C3866AXI-040ES2 on my own pcb board.

When i go to program menu (ctrl + f5), i can see that my device is seen, but ther is also message: "Avaible fo use Unacquired."

When i go with pointer on device name, it shows also massage: "Unable to read memory, Debug anable is not set, Click Port Acquire to to reset the chip and enale debug. When I do it, nothing is happening, still the same error."

And last think, when i double click on device on this programing menu i've got: "Unable to read the silicon revision for target device 'unknown target'. Click Port Acquire to reset the chip."

I have no idea what can I do now.


Please help,

What are the pin connections that is made for programming the device on your custom board? Also, did you know that we have a production version of the silicon for PSoC3. We would recommend you to move to this vesion of the silicon.
