I running an application that enter to secure mode (without). I definitely know that the processor entered to mode :

SECURE_SYSSWT : 00009802 - my first command in the secure function to config the register to enable all dmas & jtag .

SECURE_CONTROL : 000E

SECURE_STATUS : 0062

 

section("L1_data_a_msg") void secure_function(void)/

{

  /* Enable JTAG */

  *pSECURE_SYSSWT = 0x00009802;

  ssync();

 

  log_authentication_results();

}

after  I configured the SECURE_SYSSWT I wasn't able to stop the program at the next command :"log_authentication_results();"

farther more the program is reaching to "__unknown_exception_occurred"  :

 

SEQSTST : 0000E021

EXCAUSE : 21

HWERRCAUSE : 03

 

is there someone who is familiar with that problem?

Thank in advanced

Alon
