How to get Bluetooth Bootloader up and running??

[Flemming Jensen]

Hi,

I am having BIG problems getting the Bluetooth Dual Bank Bootloader sample to work!

I am using Keil 5.18 and using SDK version 9.0.0 and also tried 10.0.0. I have S310 working together with a application using both ANT+ and BT. No problems what soever...

But now I want to add a bootloader functionality so that I can update the firmware remotely if I need to.

I use the following recipee:

• First I clear the CPU using nRFStudio
• Then I install Softdevice S310 v3.0.0 in the device (116KB)
• I use the sample BLE_DFU_DUALBANK_S310 (not sure this is the exact name :))
• From either V9 or V10 SDK
• Build the project (which takes 3 compile iterations optimizing for size)
• I have then tried installing the bootloader 2 ways.
• One way is just clicking upload in Keil which uses jrfprog
• Second way is using nRFStudio and install the bootloader here by using the .hex file

I reset the board and then use "NRF Toolbox" on my Android Phone to try and search for the device. But it never comes up.

Actually I think it crashes becuase I cant even lit a LED....

I am pretty stuck here. I cant seem to be able to single step the bootloader for some reason. This way I could possible identify what is going wrong...

Please help

Hi Again, Now I have some progress - but the bootloader is not running yet... Here goes: As you suggested - I did get HardFaults - so that was the reasone why I ended up there when debugging. I compared memory setup between my application and my bootloader and could see that the bootloader was using 0x2700 - 0x8000 and application was using 0x2200 - 0x8000. Strangely when giving my bootloader more memory (0x2200 - 0x8000) i did not get the HardFault any more. So now I get through the startupcode and my LED gets LIT! Whoohoo! The next problem is when the bootloader calls pstorage_init also in the initialization process. This fails. Why is the bootloader using pstorage and for what? So I have to debug some more later on
