nrf52832 s132 sdkv14.0 RAM/ROM Keil

[stheinema]

I am struggling to figure out the correct IRAM/IROM settings in keil for the ble_app_beacon example in sdk 14.0.

I am currently using this example on an nrf52 DK and will then be deploying to a Red Bear ble nano v2 (nrf52832).

I am able to flash the code to the dk board with no errors, however the led is not flashing and the board is not broadcasting.

Here are my current settings, I assume this is a RAM/ROM issue but it could be that I have another setting incorrect:

Hi Stheinema!

The settings I have for the ble_app_beacon example in SDK 14 is:

Note that you might have to change these settings depending on what changes are made to the code.

The fact that the DK is not advertising, and your led not blinking might be because you haven't flashed the Softdevice. Are you sure that the softdevice was succesfully flashed to your device before your application? If you did, what softdevice version did you use?

Best regards,
Joakim

Thanks Joakim, my board is flashed with S132 v5.0. I just tried those settings with no luck unfortunately. The board flashes successfully but then no LED or advertising. I re-flashed the soft device for good measure. I am using the original example code and I know that I had this example working once before on this board before I tested out some other code on it. Do the values you provided change given the soft-device I am using?

I see! Could you try to flash the pre-compiled hex file and see if that works? You will find it in this folder: <SDK_INSTALL_FOLDER>\examples\ble_peripheral\ble_app_beacon\hex.

Looks like the pre-compiled hex runs correctly.

Ok, atleast we can rule out a faulty board.
When you flash the example (The one that doesn''t work), do you get any output on your terminal (e.g Putty)?
However, since you are trying to flash an unmodified example, the easiest thing to do might be to simply delete the ble_app_beacon folder. When you delete it, you can download the SDK again, unzip it, and copy the ble_app_beacon folder to your original SDK ble_peripheral folder. The settings straight out of the SDK should work.
