Hi,

Could you use the debugger and set a breakpoint at line 20 and confirm that it's able to reach the breakpoint? I'm not entirely confident that it is based on your observation on the LED blinking.

Yes, you are rigth. But the brief of sd_flash_page_erase() said that it returns with erasing success while the sofedevice was disable, i do this at first.

Hi,

sd_flash_page_erase() is asynchronous, which means that you have to wait for NRF_EVT_FLASH_OPERATION_SUCCESS event to be generated for the operation to be completed.
