举个例子，假设我现在把PF1的前100byte overlay到EXMEM上，按照PD的标定习惯，修改标定量值使用的是标定量的PF1的地址；但基于英飞凌OLDA的描述，是可以通过OLDA overlay到EXMEM的方式去修改EXMEM里的标定量，那标定工具如果用OLDA对应的memory address去做标定，就应该要把OLDA和PF1的标定量做一个地址mapping，这个工作是标定工具提供商做的？还是需要ECU基础软件去做适配？

Hello everyone, I need some help.

I need a good understanding of what pre-calibration and post-calibration consist of.

I need to know in detail what they are, what they do and what role they play.

Thanks in advance.

ALM6[2] belongs to module "INT" as indicated in below picture:

But I didn't find this safety flip-flop feature in related chapter (chapter 16 Interrupt Router (IR)) in user manual.

And safety manual didn't have a detailed description either.

Could you please help to explain the cause to this ALM6[2]?

For TC387, assuming that an interrupt source has the highest priority, from the start of the interrupt request ，through arbitration, responding to the interrupt request, saving CSA register data, storing stack data, until the final PC pointer points to the interrupt function entry address, how many clock cycles are required for the entire process and approximately how many microseconds does it take? Can Infineon provide a method for measuring interrupt response time?

Hello experts,

I try to map data cache into RAM area using TC33X by following (simplified) sequence:

CPU_DCON0 = 2
MTU_CLC = 0
MTU_MEMMAP |= 1

This works fine after SW flashing and debugger stays connected. Without debugger the SW hangs and even with debugger after first reset the SW gets class 4 SBE after MTU_MEMMAP write access.
Any idea what may be wrong here ?

Thanks in advance for any hints.

Hi team,

 We made our custom board with Aurix Tc397x. Do we need to program the UCB memory area for the first time?

What would the default data at UCB region?

Help is most appreciated.

Shafi.

What is the "keyword" to define the array(static /global /local) in NVM and local memory ?  Also how about the keyword to alignment with 32 bits . Thanks. Xianju 

Hello,

I would like to measure the idle time of the microcontroller (Aurix TC399). Can you please help me with this? 

Is there any register we need to monitor or how can it be done? 

Looking forward to your response.

Thanks in advance! 

Hi team,

I'm trying to test the ALM9[16] and ALM9[17] for safety functioning of the controller. however, I couldn't find enough details on how to inject error and check the alarm. however, I can find test on PMS MOBIST but not on HSM or it is the same.

if someone can help me out it would be great help. Thanks in advance.
