使用ADS软件编译程序卡住在40%，此时显示编译已经基本结束，CPU(因特尔i9-13)占用率从80%降低到5%，说明此时CPU基本已经停止编译工作。但是编译无法正常结束，卡住一小时后不得不停止编译。且查看不了正确的报错信息。编译ADS自带的TC297工作例程，也出现了类似的问题，只不过卡在16%，并且显示芯片的cpu0~cpu2都编译完成，但是还是卡住了...

Hi All,

I was using Aurix TC387 

When I completely erase and flash the application software there was no protection hook and software functionalities are working, when i perform shutdown the CPU and given the reset and try running the software getting protection hook showing alignment error in DSTR and DEADD showing the flash address.

what could be the reason getting alignment error after performing shutdown and run the software, as there was no alignment error when i erase completely and flashing the software.

Hello Champs,

I am facing an issue in UART working.

MCU - TC397

so I am printing logs using TERA TERM. I am using standard code as below:

void print_f(const char *p_frm, ...)
{
va_list p_arg;

va_start(p_arg, p_frm);
vsprintf(ubOutputBuf, p_frm, p_arg);
va_end(p_arg);
buf_to_screen(ubOutputBuf);
}

I am able to print the characters and constants values such as below,

print_f("\n\nRESULT_START\n");

but when I am using anything such as

test_print++;

print_f("\n\nRESULT_START value = %d\n", test_print);

Then everytime in Tera Term I get RESULT_START value = 1, the test_print value isn't changing!!!

Am I missing anything here.


Thanks in advance!

Could anyone help to understand the root cause?

Hi everyone.

I would like to ask you how I can measure the execution time of a function using the STM module.
Would it be possible to measure it via the BSP default timer by assigning two variables of type Ifx_TickTimer, respectively the start and stop variables the number of ticks via the now() function of the Bsp.h library?
Also, to obtain these values during execution, is it mandatory to do so via debug or can I print them out via printf? I have tried printf but cannot print out the values (I have included the stdio.h library)

In TC38x DataSheet, I see Retention time and Tj according below example temperature profile. Can you provide temperature profile for TC387Q?

And Is the data Flash of TC387Q robust with an endurance of more than 1k write/erase cycles and data retention over 15 years with a fault  drop out of less than 10 ppm of all devices?

Hi all

I've activate startup calibration and I was looking if it was mandatory to do also the post-conversion calibration and what are the effects to skip it

from the manual we have only this note

"Postcalibration steps can be appended to each conversion. Since variation caused by aging is very slow and
postcalibration leaves the capacitor discharged, for the current version of the converter postcalibration shall be
disabled (most applications are restarted periodically and, therefore, also repeat the start-up calibration)."

but I can't find any data related to "very slow".

Can I skip the post calibration if my application could work for 24hr continuosly? and if could work for 1month/yr continuosly? 

Is variation caused by aging only the only cause that require a postcalibration?  

later in manual we have

"In systems with a stable reference voltage, it is recommended to disable postcalibration permanently to avoid
these effects by setting bit DPCAL in register GxANCFG (x=0-11).
In systems where the reference voltage is influenced by temperature, postcalibration can be enabled temporarily
during certain operation phases to compensate these effects."

so it seems that at least post calibration is needed if the reference voltage is not stable.

Other conditions need to be taken in account?
