You should compile and run easypdkprogtest and then check the output voltages reported from easypdkprogtest + measure the voltages on VDD and VPP.

To compile easypdkprogtest on windows, please have a look at the INSTALL file in the software repository:
https://github.com/free-pdk/easy-pdk-programmer-software/blob/master/INSTALL

(On Windows you need to install MSYS2 and install a compiler (gcc) for MinGW or MSYS2 : you can find multiple guides on the internet like this one: https://www.devdungeon.com/content/install-gcc-compiler-windows-msys2-cc)

Hi freepdk,

Thanks for all those links, I have installed MSYS2 and all suggested packages
I finally succeed to compile
Now reading vdd 4.97 vpp 4.90 vref is 3.3 on screen
REAL are vdd 4.98 vpp 5.00
what should be the value ?

Launching easypdkprog probe always give me "Probing IC... Nothing found."
I try a PFS 154 then PSF 173 (fresh new) same result
What next ?

from easy-pdk-programmer-hardware.

@Skywalkerf34 :
VDD = 5.00V / VPP = 5.00V are the values easypdkprogtest sends.

Your values are 100% good. This verified that >98% of the PCB is working correct.

The remaining things on the PCB which might be wrong are just the resistors R18,R19,R20,R21,R22 (which is very very unlikely) or the soldering of the STM32 / the header is not good.
=> This should be easy to verify with a multimeter (check for shorts between the data lines on the header, check for continuity to resistors / resistance to the STM32).

After that said, it might just be that all your PCBs are working correct and you have a problem with the socket where you place the IC inside. Also make sure to place the IC (PFS154 / PFS173) at the bottom of the socket...

@freepdk
Thank you so much for your support
I have checked the MCU and resistor to header carefully and everything is right
But still same answer :-0
the "only" thing I didn't check are those adapter PCB design for PFS and PMS do you know if are they right about the design (schematic) ?

from easy-pdk-programmer-hardware.

@Skywalkerf34
Which adapter PCBs are you refering to? The programmer is designed to use of the shelf sop16 adapter to be plugged in the programmer directly: google search "sop16 adapter" => https://www.google.com/search?q=sop16+adapter

@freepdk
those here : https://github.com/free-pdk/easy-pdk-programmer-hardware/tree/master/adapter-pcbs
I think I put the finger on...those are for SOT6 :-5

from easy-pdk-programmer-hardware.

Better read...10 times
I put the question seeing that PCB was exactly pinout form PADAUK DATASHEET and remembering designing those PCB crossing pin...

@Skywalkerf34
Unfortunately I don't have any experience with the adapter from here: https://github.com/free-pdk/easy-pdk-programmer-hardware/tree/master/adapter-pcbs
For me it looks like you need the exact same socket as the creator of the adapter PCBs used. In case you just have a similar looking socket the pinout of the socket might be different.

I created a wire based adapter myself in the past... It took me also some tries to get the wiring right. So maybe something is wrong with your adapter / socket.

@freepdk

My mistake!
I was stupidly thinking PADAUK did different pinout for the PFS and PMS series, so the adapter was necessary
As I solded my SOP 16 adapter to the universal I just make a "reverse" for bottom to plug on the programmer and...

TADA.... IT WORKS !!!!!!

The so call adapter are only necessary for the small SOP6 models but I didn't paid so much attention about PADAUK datasheet PINOUT nor the "SOP6" indication on the adapter page....I shoud have read more carefully again and again and again

@Skywalkerf34

TADA.... IT WORKS !!!!!!

Great. Closing this issue now :-)

from easy-pdk-programmer-hardware.

@freepdk
Now I got one working I can fix the few other programmer I have left
Maybe the next step would be for me to re-design a little the PCB with some change (diode really too small; OSCILLATOR could be SMD etc...
But you already do a GREAT JOB !!!!
thanks again for this great support

from easy-pdk-programmer-hardware.

There is already a re-designed PCB (called "lite") which reduced parts (no diodes at all).

The OSC and many other parts been chosen just by "lowest price" on LCSC almost 2 years ago... Back then the complete BOM was <US$2 :-)

Things changed a bit.
