CC2745P10-Q1: CC2745R10E0WRHARQ1 issue

Part Number: CC2745P10-Q1

Tool/software:

1. About programming HSM FW issue

The above method for programming HSM FW comes from"SWCU195-CC27xx-TRM-for-FCS2.pdf"

There are a few questions I would like to ask about this programming method：

  1. “SACI HSM FW provisioning command” Cannot find this command in the document,I would like to know detailed information about this command.

  2. About programming HSM FW provisioning via SACI command,The description in the document is not very detailed, for example: I don't know which address to program HSM FW to, how to verify if the programming is correct after programming is completed, and so on;Can you provide a detailed and complete example of programming HSM FW through SACI?

  3. About HSM FW size,My chip version is PG2.0, does that mean that the last 128KB of flash is reserved for HSM use?But the document "SWCU195-CC27xx-TRM-for-FCS2.pdf"said that the HSM FW consumes at most 96KB of main flash.

    4. About HSM FW version and rollback ID,How should we use them in programming?

    5. Programming order for flash, CCFG, SCFG, and HSM?

2. About SCFG programming

I want to know how to program the SCFG region through SACI command,Because the currently provided documentation(SWCU195-CC27xx-TRM-for-FCS2.pdf) does not provide a description of programming SCFG.

3. About SACIdebug/control command 

In CC2745x CCFG region (debugCfg),In the hw_ccfg. h file of the SDK, there is no password id configuration here.I would like to know if there have been any changes to the debug command for cc2745x?

Currently, I am using commands "SACI_CMD_DEBUG_EXIT_SACI_HALT" and no protection applied to flash,but when reading Flash, all returns are 0,why?

    Hello,

    The next iteration of the TRM will have all the information needed to do HSM and SCFG provisioning. As of today, this information is not available. 

    The authenticated debug is not supported currently, and will be supported sometime after TRM. 

    I will notify you once the next iteration of the TRM is available.

    Hello,

    What PG2.0 device do you have? Can you please update to the latest SDK?
