I have a project with a Cy8C4013SXI-420. This is a SO8 part.
I have the programming configuration as:
1.6MHz (also tried slower)
3.3V
Power Cycle Mode
5 Pin Header
SWD
I have the following wires connected from the MiniProg3 to my target board:
VTARG to my 3.3V rail (PSoC supply). No other power applied to the board. There is no other significant load on this rail, maybe 30mA.
GND to GND of course
SCLK to PSoC pin 1 (P3_1)
SDAT to PSoC pin 8 (P3_0)
The programmer cannot connect. It takes a long time, like 30 seconds, then shows the target as "Cortex-M0", but won't connect. Sometimes it doesn't even show that.
Put a scope on VTARG and it is slowly cycling on and off to 3.3V.
I have changed the chip, same result.
I have had similar issues with the standard 5 pin programming interface before, but only when I have needed to put wires to extend the programming interface. I have found that it will NOT detect the target if those wires are more than maybe 2" long. So in this case, because I have wires, they are about 1 inch long.
Anyone have a solution for this?
Thanks in advance -
