Help to debug it (Almost there!)

Hi, I've soldered all components, and flashed the manna-harbout driver correctly, but the trackpoint doesn't work yet, so I'm measuring with a multimeter. This is the current I get:

On the driver board

RST (0.0V)	GND (0.0V)	VCC (4.33V)	CLK (4.33V)	DATA (4.33V)
2u2 -		2u2 +
100k	100k
		4k7 1/2		4k7 1/2
		4k7 2/2	4k7 2/2
	GND (0V)	VCC (4.33V)	SCK (4.33V)	SDA (4.33V)

On the trackpoint's 4 pins I get:

0.93V 0.93V 0.0V 1.93V

From this results, I find weird RST has 0.0V. Is this normal? On the trackpoint everything looks about right, but I don't have data to compare.

I flashed the drivers with the instructions you provided BTW

sudo make clean && sudo make crkbd:manna-harbour:avrdude-split-right MH_MODULE=trackpoint MH_AUTO_BUTTONS=yes MH_RGB=matrix LTO_ENABLE=yes
sudo make clean && sudo make crkbd:manna-harbour:avrdude-split-left MH_MODULE=oled MH_OLED_MODE=static MH_OLED_IMAGE=qmk.c MH_RGB=matrix LTO_ENABLE=yes

Just to be sure I made another driver board, and this time I'm getting this values:

driver board

RST (0.0V)	GND (0.0V)	VCC (4.25V)	CLK (4.25V)	DATA (0.05V)
2u2 -		2u2 +
100k	100k
		4k7 1/2		4k7 1/2
		4k7 2/2	4k7 2/2
	GND (0V)	VCC (4.25V)	SCK (4.25V)	SDA (0.05V)

trackpoint's controller:

DATA     RST     VCC       GRD     CLK
0.05v    0.0v    4.25v     0.0     4.25v

On the trackpoint's 4 pins I get:

0.0V 0.0V 0.0V 0.0V

driver board to controller: Most likely ok. Controller to trackpoint: Seems to be failing.

Researching...

EDIT: Nah, I think I fucked up the controller. It gets current but it doesn't reach the tp pads. At least the driverboard should be fine now. I'll tell you in 1 month when I get new trackpoints.

Also, I'm using unpolarized ceramic capacitors, that's probably causing problems too. I'm gonna try with "3216A 16V 2.2UF 225C" instead.

Meanwhile I've made the screen in inkscape so anyone can just print it. corne-screen.zip
