Thingy91 3.3v power domain sleep mode

[Andrew B]

I am trying to switch off the 3.3v power domain to save power.

I can disable it by using adp536x_buckbst_enable(false) in board_secure.c but when I try to use the same function call in main.c the function call hangs with no error code.

Any help would be appreciated.

Thanks

Fixed the issue, the adp536x_init() function call had the incorrect name for the ADP536X I2C and was not initialising it correctly. Now the adp536x_buckbst_enable(false) function call works.
