Running the BLE bootloader example

[Javier]

Hello,

I have been trying to make the BLE bootloader example works without succes. I am getting stuck after uploading the Softdevices and the Bootloader.

Step by step (Version - nRF5_SDK_11.0.0_89a8197):

• First I upload the proper Softdevice - s130
• Then I upload the Bootloader: nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10028\dual_bank_ble_s130\arm5_no_packs
• Now the MasterControl panel doesn´t detect any "DfuTarg". As far as I understood, if there is no code, the bootloader will start automatically, if not at the start push the button 4, true?

Any help will be wellcome. Thank you for your time,

Javier

Hi Javier,

I am assuming that you are following this step-by-step guide from our Infocenter.

After you have flashed both the S130 v2.0.x SoftDevice and the Dual Bank Bootloader, LED1 and LED3 should be turned on. If they do not turn on you can try to press the reset button or power-cycling the board.

Yes, you are correct, the device will alwyas branch to the bootloader if it is present and if there is no application present, then th device will remain in bootloader mode.

Best regards

Hi Bjørn,

I am following this example: link text

Also I am using the PCA10004 Rev.2.2.0 and the Master Control Panel doesn´t detect the board. Maybe there are problem with compatibility?

Best regards, Javier

If you're using a PCA10004 Rev.2.2.0 board, then its higly likely that you're using a nRF51822 IC revision 2 chip, please check the chip markings against the overview on this Infocenter page. If you're using a revision 2 IC, then its not compatible with SDK v11.0.0, please see the compatibility matrix found here.

You are right, the chip version of the PCA10004 Rev.2.2.0 is the N51822QFAAG0, non compatible. Then I have a custom board with the chip N51822QFAAG2, but this one also enter in the revision 2 IC? I will check with another custom board with N51822QFAAH0, revision 3.

Thank you.

Happy to help. Let me know when you've tried this on a rev 3 IC.
