Hello,
Finally, after some struggle, I achieved to port the bootloader to s120 V2.1.0 and work just great on a dev. board with nRF51422. But now I have another problem:
All the examples from SDK are for nRF51422 and I need to use a custom board with nRF51822. With the app I managed to make the proper changes and it works in my board but not the bootloaders.
I have a 32MHz system clock in my board and for the soft device I use the default internal clock (NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_4000MS_CALIBRATION).
Ports work good for the apps, but not for the bootloader. Both s120 and s130 bootloaders works in a dev board I have with nRF51422 but I am not able to port them to nRF51822.
As far as I understand ANT feature is one of the important differences between the chips and I tried to exclude all the files and defines related to it from the bootloader project... but without success.
Any advice about how should I port it would be much appreciated. Thank you...
