will 14681 turn off external flash when entering sleep mode?

Hi, I am testing sleep function using 14681, I find that even in sleep mode, my custom broad still draw over 2mA of current, I am suspect is the external flash still drawing current after 14681 to go sleep
but will 14681 turn off external flash? because I try use qspi_automode_flash_power_down() to power off the flash, the current did go down but result hanging the 14681,

Also, do you have other tips where I should look for the sleep mode current draw problem?

please help, thank you.

Hi andoridfm2013,

Hi andoridfm2013,

 

Please change the value of the dg_configFLASH_POWER_DOWN to 1 into the custom_config_qspi.h. Take care that with this way you will have a delay until you re-initialize the flash and wake it up again. It is strongly recommended to not use the SDK functions, as qspi_automode_flash_power_down().

 

Thanks, PM_Dialog
