Part Number: TMS570LS1224
Other Parts Discussed in Thread: HALCOGEN,
Tool/software: TI C/C++ Compiler
Dear TI Experts,
I decided to post to this forum, as I could not find an appropriate forum for posting HALCoGen questions.
HALCoGen Version: 04.07.01
I have been analyzing the HALCoGen generated code for the TMS570LS1224, in particular the sys_startup file.
When checking the power-on reset condition, the last "else" statement is supposed to cover the case when the CPU reset was caused by software. One would expect a "User Code Begin" block there, however there is none. It is only after the squiggly bracket after closing the "else".
Here is the section of code I am referring to:
/* CPU reset caused by CPU self-test completion */
else if ((stcREG->STCGSTAT & 0x1U) == 0x1U)
{
/* Self-Test Fail flag is set */
if ((stcREG->STCGSTAT & 0x2U) == 0x2U)
{
/* Call CPU self-test failure handler */
cpuSelfTestFail();
}
/* CPU self-test completed successfully */
else
{
/* clear STC global status flag */
stcREG->STCGSTAT = 0x1U;
/* Continue start-up sequence after CPU STC completed */
afterSTC();
}
}
/* CPU reset caused by software writing to CPU RESET bit */
else
{
/* Add custom routine here to handle the case where software causes CPU reset */
}
/* USER CODE BEGIN (21) */
/* USER CODE END */
}
/*SAFETYMCUSW 139 S MR:13.7 <APPROVED> "Hardware status bit read check" */
else if ((SYS_EXCEPTION & SW_RESET) != 0U)
{
/* Reset caused due to software reset.
Add user code to handle software reset. */
My presumption is that the "/*USER CODE BEGIN (21) */ should be inside that "else" statement above it, otherwise any user-written code would be deleted when generating code from HALCoGen.
Thank You for taking the time to look into this!
Kind regards,
Mihail
