Unable to read SE info: Se05x_GetInfo fails

[Riz]

Hi @Kan_Li , Hi @michaelsalfer 
The Se05x_GetInfo fails with below error.

smCom :ERROR:Can not select Applet=SE050:C'
smCom :ERROR:Failed (SW_FILE_NOT_FOUND) selecting Applet.  (Len=16)
      A0 00 00 03    96 54 53 00    00 00 01 03    00 00 00 00
sss   :ERROR:SM_I2CConnect Failed. Status 6A82
App   :ERROR:sss_session_open failed
App   :ERROR:ex_sss_session_open Failed
smCom :ERROR: phNxpEse_Transceive ESE Not Initialized
smCom :ERROR: Transcive Failed
App   :ERROR:Could not select ISD.
App   :ERROR:se05x_GetInfoPlainApplet Example Failed !!!...
App   :ERROR:ex_sss_entry Failed

Briefly checking the code, I could see the error originated from here (sm_connect.c).
Not sure what the comment "// Applet can not be selected (most likely it is simply not installed)" really means here.

Any hints?

if (sw == SW_FILE_NOT_FOUND) {
// Applet can not be selected (most likely it is simply not installed)
LOG_E("Can not select Applet=%s'", SE_NAME);
LOG_MAU8_E("Failed (SW_FILE_NOT_FOUND) selecting Applet. ", appletName, APPLET_NAME_LEN);
return sw;
}
else if (sw != SW_OK) {
LOG_E("SM_CONNECT Failed.");
sw = ERR_CONNECT_SELECT_FAILED;
}

Hi Kan,

This is on Linux platform and chip is SE050C.

Hi @vishwanchandapu ,

Thanks for the information! May I have the MW cmake configuration on the Linux platform? You may run "cmake . -L" in the building folder to have such info.

Thanks for your patience!

Have a great day,
Kan

@Kan_Li 

Can this be an issue of Applet not being installed at production?

Hi @vishwanchandapu ,

Actually I could only imagine this on SE051P, which comes out without any IoT Applet preinstalled. But later on even the card manager select failed. That is also quite strange. I think I would like to see a debug log with more info on the communication. Is it possible to have the cmake option "-DPTMW_Log=Verbose" in your building?

And I would like to know if this happens just on one sample or if it happened suddenly, does the error stay when using another board or after unpowering the IC?

Please kindly clarify.

Thanks for your patience!

Have a great day,
Kan

Hi @Kan_Li 

Small correction, the Chip indeed is a SE051C and not SE050C. Sorry for confusion.

According to the documentation, The Se05x_GetInfo should work with or without the applet installed.

However, the Se05x_GetInfo still failed. Do you know why this is?

We are suspecting an error during "applet upgrade" might have resulted in a corrupted applet or something which eventually causes failure in card manager selection.

Could this be a culprit?

Below is the chronology of what happened until now:

• We observed Se05x_GetInfo fails with "Can not select applet" error as reported earlier.
• Upgrade status with : sems_lite_cli_app --checkUpgradeProgress returned "1".
• A rerun of the applet-upgrade recovered the chip.

[Kan_Li]

Hi @Riz ,

A failed applet upgrade might lead to such kind of issue, but in case of a torn applet update on SE051 simply the same script needs to be run again. It will again install the applet and recover the backed up data. Did you do this already? Please also make sure the applet update file matches the product you want to apply, depending on the OEF ID.

Have a great day,
Kan

Hi Kan,

We were able to recover by running same script. 

Ideally as you mentioned get info should work without applet.

we looked into code the API "GP_Select" is failing.
  
App :INFO :No IoT applet found
smCom :ERROR: phNxpEse_Transceive ESE Not Initialized
smCom :ERROR: Transcive Failed
App :ERROR:Could not select ISD.

Vishwa

Hi @vishwaec08 ,

Is it possible to have the cmake option "-DPTMW_Log=Verbose" in your building? so we may have the full log starting from the beginning.

And I would like to know if this happens just on one sample or if it happened suddenly, does the error stay when using another board or after unpowering the IC?

Would you please clarify?

Thanks for your patience!

Have a great day,
Kan

Hi @Riz ,

May I have the info regarding the platform you run the demo on? Thanks for your patience!

Have a great day,
