Having trouble acquiring target
I have played around with the evaluation kit for a while and now made my own target board but have trouble connecting to it for debug and programming.
The device is CY8C888AXI-LP099
Using Creator 3.0 (SPI) and Miniprog3 (version 2.2).
The Target is powered by 3.3V
The connections seem to look ok when I compare with schematics of the 5LP module board.
The following pins are connected to debug (I have tried setting JTAG 4-wire, and SWD in software but neither connects. When I attempt to acquire, I get error, unrecognised device).
The 10 way header has pin 1 = 3.3V, 3,5,7 and 9 = GND, 2 = TMS (P1.0, pin 20), 4 = TCK (P1.1, pin 21), 6 = TDO (Pin 1.3, pin 23), 8 = TDI (P1.4, pin 24) and 10 = XRES (XRES_N, pin 15).
The 3.3V is connected to pins 26, 37, 50,63, 65, 75, 88 and 100)
GROUND connected to pins 10,12,13,14,38,64,66 and 87
VDIOx all have 0.1uF close to IC, Va and Vc have 1uF, Vdd and Vda have 0.1 uf and 1uf. Vc only connects to other Vc pin and is decoupled (pin 39 to 86)
There must be something here I have overlooked or got wrong. Or maybe there is a setting in the software that needs to be setup before attempting top connect?
Any help much appreciated as I have some more boards for other projects need fabricating later this week and would like to include revision of this one if there is a wiring issue.
The debug socket is close (5 or 6mm from edge of 5LP). I have no External crystal connected and not using USB pins.
I suspect there may be a few of you who have found some "gotchas"on first attempt at using your own target and hope there is somehting common I have overlooked that is easy to fix
Thanks in advnce
