nRF52833 development

[deknoob]

Hello all,

I am working on low power sensor development with nRF52833 as target. I have some questions but I'm not sure it this was addressed in some other posts.

1. I don't have nRF52833 DK but instead I use nRF52840DK for development under SES environment. What in particular should I be aware of when generating target code for nRF52833?

2. I wan't to place sensor in sleep state for longer period of time. From product spec I understand that I should use wake on RTC and no RAM retention for lowest possible power. Because of no RAM retention, I need CPU to restart after timeout, not to go to application timer timeout handler but to top of main. How can I set this up?

Thanks

Hi

The RAM should get filled up "from the bottom up", so depending on how much RAM your application uses, you should be able to turn off the "later" RAM pages of your application.

Best regards,

I am using SES and this is what I think is indication which part of RAM is used. There is something at the top.
In fact I already tried powering off all of RAM8 and it crashed.

I also tried to change RAM size in linker, to bring all used RAM closer to bottom, but it also crashed when I power off RAM8.
