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

I am sorry for not catching this earlier, but the nRF51822 QFAA only has 16 kB of RAM(0x4000) bytes. The bootloader example in the SDK is intended for the nRF51422 QFAC which has 32 kB of RAM. This means that you have to adjust the RAM size to the following:

IRAM1: Start 0x20002C00 Size 0x1380
IRAM2: Start 0x20003F80 Size 0x80   No Init: set

Does this solve the issue?

Great! Again, I apologize for not catching this earlier.
