AURIX™ Forum Discussions

For AURIX TC38x, in the datasheet the max CPU frequency is 300MHz as below - 

So with this frequency, each instruction execution time will be : 1 / 300 MHz = 3.33 ns. Is this understanding correct?

Otherwise, how to calculate each instruction execution time or MIPS. Here, the motive is to calculate MIPS for particular application.

Hi,

In case of global variables, names of the variables are not appearing in generated map file. I have declared global variable as below:

Then used #pragma to route variable to "OS_OsApplication_ASILA_VAR_INIT_SEC" linker section. It is generated in MAP file as below:

|------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| .data.OS_OsApplication_ASILA_VAR (15985) | 0x00000032 | 0x0 | OS_OsApplication_ASILA_VAR_INIT_SEC (23586) |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------|

As seen, the name of variable is not present in this map file entry.

Whereas in some cases, where data is routed to default sections, names of the global variable pop up in the map file. For example, in below snap, variable Tmr_500ms_c0 and Bsw_Core_PostRteStart do appear in generated in data_SEC section map entry.

|------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| .data.CRT._999001_temp (15963) | 0x00000001 | 0x0 | data_SEC (23614) |
| .data.Timer_Core0._999001_Tmr_500ms_c0 (16010) | 0x00000001 | 0x00000004 | |
| .data.Timer_Core1._999001_Tmr_500ms_c1 (16029) | 0x00000001 | 0x00000008 | |
| .data.Timer_Core2._999001_Tmr_500ms_c2 (16046) | 0x00000001 | 0x0000000c | |
| .data.main.Bsw_Core_PostRteStart (23175) | 0x00000004 | 0x00000010 | |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------|

How to enable this by default? I need to generate global variable with names and addresses in map file sections.
