https://devzone.nordicsemi.com/f/nordic-q-a/75115/low-power-examplel-ram-retention-pca10040Hi, I am programming the PCA10040 board (tested 2 different boards) with the ram retention example program from the latest SDK (NR5 17.0.2). With this example is supposed to hold some ram retention and then goes to system off until the button is presseden-USTelligent Community 13Fri, 14 May 2021 08:24:12 GMThttps://devzone.nordicsemi.com/thread/309716?ContentTypeID=1Fri, 14 May 2021 08:24:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a352a8c-966d-474c-9778-99f6b59e7385Susheel Nuguru<p>If you have flashed the exact same executable on all chips and the behavior is different on two chips, then the issue could be with the hardware. Can you give me the exact versions of the PCA10040 boards and the laser mark on the nRF chips for the boards that worked and also for the boards that did showed increased power consumption.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/309674?ContentTypeID=1Thu, 13 May 2021 17:02:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd05e9e9-0598-4d69-a2bd-8ba9d37a443bRneofy<p>Hi, yes I did. I have managed to get 2 out of my 4 PCA10040 boards working on mbed os with a simple timer-blinky program at 15-30&mu;&Alpha;. The other two boards are consuming above 200&mu;&Alpha;&nbsp; with the exact same program. Any ideas?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/309667?ContentTypeID=1Thu, 13 May 2021 15:00:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bf860593-8ca3-422d-8d17-9b47a5c01442Turbo J<p>Did you remember to power cycle the NRF chip after flashing?</p> <p>The debugger will put the chip in a mode that roughly consumes 0.5mA because it disables sleep states.</p><div style="clear:both;"></div>
