Bootloader s120 for nRF51822 example

[Gabriel C.]

Hello,

I am trying to adapt a bootloader from sdk examples to my nRF51822 board without success.

I am able to adapt the example apps from the SDK (I have to change the clocks as I use different ones than the ones in the dev. boards) but there is no way I can make them work.

Examples are fine, even the ones I adapted myself for s120 and the default one for s130. I tried and tested them on a PCA10028 dev. board. But none of them working on my nRF51822 board.

Is there any example for it? Did anyone managed to port a nRF51422 bootloder to nRF51822?

Thanks a lot in advance.

Best regards...

There is no difference between nRF51422 and nRF51822 except that you can't use ANT on nRF51822, so i don't think it is related to the chip swap. It seems your are saying that you can't get any examples from the SDK to work, so this is not just related to the bootloader is it? Are you able to use the debugger to see where it stops working? Does your custom board have a 32kHz crystal? Maybe this question is helpful.

I can adapt all the examples from SDK to my nRF51822 board by making small changes for the clock. I do not have the 32kHZ crystal, so I use the interna clock. Bootloader is the only one I cannot adapt to my board by changing the settings as the app...

Strange. Does the S110 with unmodified bootloader work as well? Do you have any debug possibilites?

I tried softdevice s110 and a s110 adapted bootloader from a nrf6310 board from earlier sdk's and it works.

What are the chip markings of your nRF51822? What SDK and SoftDevice version are you using?
