In the STM32 Daughterboards User Guide PB10-15 are mentioned to be connected to
jumper J2 as follows
PB15 J2.37
PB14 J2.39
PB13 J2.41
PB12 J2.43
PB11 J2.45
But I am finding that in the schematic that they are not. So if you
could please clarify.

I just verified on a STM32F103 daughterboard. It works fine.

Just ensure that you are using the latest RKit-ARM, as the schematics have been updated. However, these were valid in the older version so you should not have any problem.
Another thing is to ensure that you are not using an STM32F107 daughterboard, as the schematics are different.

Oh I am sorry I didn't mention I am using STM32F107 daughter-board . ReVa v3.3 boards and Ride7. Could you please verify for STM32F107

Hi Lokesh,

I verified on the STM32F107 daughterboard, it works fine as well.
Are you sure you are counting the pins/vias in the right order? :/

I am using STM32F107 board.
I checked with a multimeter the connectivity between the jumper and the pins and somehow
find the connectivity is not there for STM32F107.

Hi Lokesh,

I got the explanation of your problem: Our REva_User_Guide_STM32.pdf documentation had some invalid references. We corrected the document, which will be up-to-date in the next RKit-ARM release.

Here is the (corrected) chapter 4.6 named "Inventory of the STM32F107-DB connections (by I/O port)"

Anyway the *best* way to play with this is to use the dugtherboard and REva schematics: As they are in searchable pdf format, it is very easy to follow a given pin/signal by searching its name in the pdf.

i am new, but already used STM32F103 daughterboard file too. it seems quite interesting to me. but using with no run time error.
