Fast Standby Boot Base Address.

[aryandis]

Have tried to change linker script for fast standby wakeup but always error. Can you please help me how to update linker for fast standby wakeup support.

[aryandis]

all example are based on standby wakeup no fast stadnby wakeup .Do you have any example for RTD 3.0.0 based with linker updated.?

Hi @aryandis,

The examples have fast wakeup too.

For instance, S32K344_GPIO_Wkup_S32DS_3_4_RTD_LLD_2_0.zip

include/Wkup.h

src/Wkup.c

Linker:

have configured boot base address 0x00402000 in MCU for standby wakeup and also updating linker with below info.

After adding  KEEP(*(.fast_wkup_boot_vector)) in .pflash getting error mentioned above.

How i can adjust size in this linker.  ?

HEllo @aryandis,

Can you share the linker file here?

You can adjust the size of each SRAM section as needed, but the total combined size of all sections must not exceed the actual SRAM capacity.

reference from example mentioned in this link.

[aryandis]

can you lease also share me what configuration i have to do for fast standby wakeup. since i have used some of the reference and have done for fast standby wakeup

[danielmartynek]

Hello @aryandis,

All the necessary steps are demonstrated in the provided examples.
To enable Fast Wakeup, you must configure the boot address, which sets the entry point after wakeup.
This configuration is done by writing to the DCMRWF5 register, where you specify the base address of your custom vector table in standby SRAM and enable the Fast Wakeup mechanism.

have done this configuration but still no wakeup is working.

[danielmartynek]

What about normal wake-up, does it work?

I would recommend that you create a support ticket and share the whole project there privately so that I can test it.

standby wakeup working but i need for for faststadnby wakeup .

here i have done memory map.

.fast_wakp_boot_vector

0x20400000  0x0c load address 0x00402000

0x20400000    .= ALIGN(0x1000)

Hello @aryandis,

Please create a support ticket and share you project (privately) so that I can test it.

Thank you

have one requirement i want to do GPIO/CAN/RTC wakeup wakeup once it enter in sleep mode (which operating mode have to refer CORE_STADNBY ,STANDBY or FAST STANDBY or something else). after wakeup it should go to ISR and from ISR i can call EcuM_Checkwakeup for wakeup system.

Please guide me with configuration for RTD 3.0.0 .

[danielmartynek]

Can you please create a new community thread for the last question?

Regarding the fast wake-up, I would need to test your project - ideally through a support ticket.

Regards,

Daniel

Hi @aryandis,

There are several examples demonstrating the use of Fast Wakeup available here:

https://community.nxp.com/t5/S32K-Knowledge-Base/S32K3-Low-Power-Management-AN-and-demos/ta-p/152772...

These examples are built using RTD 2.0.0. If you plan to run them, I recommend installing a fresh instance of S32 Design Studio 3.4 with only RTD 2.0.0 added. This helps avoid compatibility issues.

Daniel
