STEVAL-CTM010V1 couldnt able to connect with PC via rs232

[AJijo.1]

I am working with ctm010v1 got this communication error, Any documents available for communicate the eval-board with pc.

I just done following steps :-

1. created project and uploaded the firmware successfully by using st utility.
2. Just for checking without giving ac supply. By giving external 5v to the 3.3v regulator input and getting proper 3.3v in all 3.3v points for trying to verify the board got connected.
3. kindly correct me where i am doing wrong.

 

with regards,

JIJO

Did you solved it, and if, what was the problem?

Haha,it's just not true!

There is a mistakenly soldered components on the board.

R99 should be 4k7, but 220R is soldered.

It is an optron pull-up, and the signal is just unable to go to '0'...

Lets see how many surpises exist ot that board...

ST, this is ridiculous!

Hi

I have the same problem, but still no solution. I have already tried STLink-V2, STLinkV3, I2C. No connection possible. So I can't upload the firmware.

(I use MCW 6.3 - select the Ribgt board and my motor - have generated the code - everything is fine, except for the upload)

 

kind regards
