Temporary modification: resistor parallel to C94

Hi
I noticed one small but important anomaly regarding adding the resistor in parallel to C94 (it is about MCU stand-by current consumption).
On this page:
https://www.amateurfunk-sulingen.de/wiki/doku.php?id=ovi40build:uiboardbuild
when reading in German it is written to add 56 kOhms in parallel to C94. When the same page is changed to English the "K" is gone and it reads: "Please try 56 ohms as the value".
Then I tried to find which is the proper resistor value by examining the mentioned F746 Discovery board schematics but all I see there is 10k resistor going from NRST to + 3V3 while in the OVI40 the C94 goes from NRST to the GND (so would the suggested resistor in parallel connect to the GND).
To keep it short, my question is: which is the right one resistor, 56 kOhms or 56 Ohms?
I also suggest to rename the current text "Temporary modification: to C94 resistor in parallel" to read as follows: "Temporary modification: add resistor in parallel to C94". The rest of the text also needs some amendments for more clarity.
Additional observation, if I may:
OVI40 documentation is rather weak and at certain points needs more clarity. Wiki in its current form is hard to follow and some translations bring more questions than answers. Often I go back to German language and I put the original text into the Google Translate, but sometimes even that doesn't help - and it is time consuming. In order for the OVI40 to be successful project proper documentation is as important as the product.
Please don't take this words as criticism but as a wishful user comment.
Kind regards,
Janez, W4/S58J

yes, the „k“ was eaten during Google Translation
56 kilo Ohm (56000 R) is the correct and tested value

The Wiki articles exist in 3 languages - German, English and French
Using Google Translate to machine/translate the German article to English usually makes matters worse.
This is why the articles have been manually translated. As Andreas said any contributions are highly welcome.
Please check the flag symbol in the menu bar of each Wiki page. Use the flag icon to change to the English Wiki articles, as explained here:
https://www.amateurfunk-sulingen.de/wiki/doku.php?id=en:ovi40wiki:wikihowto
You may either do changes in the article directly or, at your choice, leave your observations on the bottom of each Wiki page. Either case will generate a notification and your observations / modifications will be noted.
Best
Gerd.
