[Prasad_330]

hi

Hi @Prasad_330,

Make sure you are correctly flashing the projects:

You can use the following community posts as reference:

• HOWTO: download separate elf/srec/hex file to microcontroller using S32 Design Studio - NXP Communit...
• HOWTO: debug multi-core project in S32 Design studio - NXP Community

Hi Julian_AragonM

All the above mentioned configuration are properly configured in my project

Hi @Prasad_330,

Could you elaborate on the issue? Is it going into hard fault when stepping into the function? Could you debug step by step to see which line causes the problem?

Hi Julian_AragonM,

I am configuring the PTB19 as the wake up and PTE10   as output which drives the LED

i am able to put the controller into the standby mode but i am not able to wake up it.

The Led will be turned ON after controller wakes up.

I am attaching the code.

Plz suggest me what is the right configuration

Hi @Prasad_330,

I can see in your configuration that FAST_STANDBY is used. You can copy over the configurations from the S32K3 Low Power Management AN and demos (GPIO Wkup S32K324):

The value of McuDcmGprConfiguration.boot base address for Fast wake up must be same with the address of FastWkupBootVectorTable, so add a ".fastboot_vector" section in linker files:

You can configure the fast standby, or use normal Standby as in the example:

Best regards,
Julián

Hi Julian_AragonM,

Thanks for reply.

I did not configure the clock for standby mode. that is the reason i was not able to wake up from. Know i am able to wake up from the can.

Thanks  Julian_ArogonM,

I installed  RTD V2.0 and S32DS3.4 and started working on it .

I tried S32K324_GPIO_Wkup_S32DS_RTD_LLD_2_0_M7_0 example just to test, but is not coming out of

" Power_Ip_Init(&Power_Ip_HwIPsConfigPB)". I did not make any modification. 

Can you plz help me.

Hi @Prasad_330,

You can look into these examples: S32K3 Low Power Management AN and demos.

These examples are based on RTD V2.0 and S32DS3.4, so you need to install the corresponding software.

Best regards,
Julián
