AM2631: Trouble using the am263x otp key writer

Part Number: AM2631

Hi Experts,

I have trouble using the otp key writer for am263x. I am seeing below issues, I summarized it in the  pdf  e2e_am263_security.pdf 

For the record, I summarize them in below items, please find details in the pdf.

Certification generation:

  1. The command in the guide seems using incorrrect path
  2. When using git bash, I am seeing file not found error.
  3. Since I am not able to run .sh successfully with git bash, I run the .py with windwos console
  4. The example command in the guide is incorrect.

Example compilation:

  1. The include path in makefile is incorrect
  2. The path for imports.mak in the makefile is incorrect
  3. The path for bin2c in the makefile is incorrect  

I fixed the below issues based on my understanding. Now I have the otp key writer example compiled successfully. The next step should  be loading the image to the Flash. I'd like to comfrim if I am ok to move on since I changed a lot from the guide (because I am not able to follow it)

BTW: can I test this function with LP? The guide saids it's only tested on control card 

SDK version is 

  • mcu_plus_sdk_am263x_11_00_00_19
  • otp_keywriter_am263x_SR_11_11_00_00_02 
  • tifs_am263x_11_00_00_01
  • CCS2030
  • sysfoncig 1.25

Could you please help looking the issue?

  • Hi Hang,

    May I know which documentation are you referring for OTP KW?

    Please refer the README in the package

    Here, the paths are updated correctly in the build section.

    Could you follow this procedure?

    Thanks and Regards,
