Automate Production Programming

[bsuthar]

Hello Team,

To address mass Programming of Customized board , Looking help to have Batch File / Python Script which accomplishes Following Task :

1. Flash The Hex file

2. Set RDP1

3. Read UID (96-bit ) of MCU

4. Log UID and Time into CSV

I tried with batch File using STm32Cube Programmer CLI.exe , but Failed to connect with ST-Link.

yes, I am Using SWD Debug Interface. 

I am not sure uf any scripting Template is alraedy ready with CubeProgrammer. 

[Bob S]

Batch file with CubeProgramm CLI should work - we do it all the time.  Post your batch file and whatever output/error messages you get.

[bsuthar]

Hell @Bob S ,

Pls. find attached one Bat File FYR.

You can suggest related document / post already available to understand it.

1. Following is , When I run it with Windows PowerShell

2. When I run in CommandLine

3. CSV LogFile

4. Folder view on my PC , all file in same Folder

[Bob S]

And what does that error message lead you to?  I'm guessing the batch file turns off echo.  If so, enable it so you can see all the lines that execute.

Please post your batch file here instead of attaching it.  My work environment restricts ZIP file downloads.

[bsuthar]

Okay, Bob S

Here is the Batch Scripts , FYR. Error windows was shown in Previouse Post , 2nd Image.

That is not the same file that generated the error messages in the 2nd image you posted.  In the image, the prompt is "Enter board number", but in the file you posted it is "Enter board ID".  The file you posted also has echo lines that do not appear in the image.  And other differences.

So... back to my suggestion above:  Remove or comment out the "@echo off" line at the top of the file and then try again.  Look at exactly which line fails.

[bsuthar]

Hello @Bob S ,

Ok , removed Echo off and Run same code.

After Entering Board ID batch file closes immidiately. See below Commnad consol Msgs on Batch RUN :

Also, would it be possible to share Batch file Demo Code which Just reads UID from 0x1FFFF7AC and Store It to Flash From address,   0x801F3F0. Total 96 bit.

[Bob S]

There is nothing obvious why your batch file should just quit/exit after entering the board ID.  So debug that.  Divide and conquer - try removing everything after that "set" line and just add an echo.  Or try removing everything before that "set" line, see if that makes a difference (it shouldn't, but you never know until you test it).

Hello Bob,

Since you mentioned "Automate production programming through batch file you do all the time" , we were expecting some ready to go script / pointers if you can list out. 

Considering your suggeston for breaking down code path  , i have removed the Wrapper and just rewrite Short batch file step by step. 

See the New Batch file as Below , Firmware Download Works and RDP1 set works fine. But, UID Read/Write Fails
