Do not enter the second deep sleep

[hiroki]

Hi . I'm trying deep sleep mode using freeRTOS on CE223508.

issue

I want to wake up using RTC or GPIO interrupt, but once I confirm wake up, it doesn't do deep sleep.
The confirmation method is looking at the current consumption.
It will be about 1.3mA during deep sleep and about 11mA when wake up.

Then continue to maintain 11mA.

Please help me if you understand even the smallest things...

thanks

Hi @hiroki, 

Can you please let us know if you are using an Infineon development kit or a custom design? If in case it is a custom design can you please try sending the device to deep sleep in an empty application and then measure the current consumption?

Hi. @Rakshith 

Thank for the reply.

I'm using PSoC 6 BLE PIONEER KIT (= CY8C6347BZI-BLD53).

Thanks .

Hi.

Maybe I solved.

I use PLL and CLK_HF0 changed to Path1.

When Device enter DeepSleep , wakeup using RTC Alarm or BLE actions.

but I can't explain...

thanks

Hello,

I observed the behavior with a GPIO interrupt in the code. After waking the device from Deepsleep(with GPIO interrupt), I observed that the system goes to Deepsleep mode again. I used the FLL clock in the project. 

Please refer to the attached modified project. 

Thanks,
