@Hung Bui I just realized the missing "defined" wasn't on the pstorage file but on dfu_types.h. Anyway, I've found more bugs on the bootloader side (easy to fix) and I have a couple of suggestions as well. Who or where should I contact to address this information? Thank you

You're right, I guess I was keeping this file from an old sdk version.

@planas: I'm glad that it worked for you. Which SDK are you using and which example are you looking at ? On my ble_app_hrs example in SDk v0.9.1 it is already defined with "#elif defined NRF52"

Thanks Hung, it works fine now. And now that you mention it, I had to fix the #ifdef ... #elif conditional before since it doesn't play well with gcc. You should add a "defined" after the #elif. This way it would work with all major ISO C compilers. The final fixed code looks like this:

#ifdef NRF51
#define BOOTLOADER_ADDRESS                    (NRF_UICR->BOOTLOADERADDR)
#elif defined NRF52
#define NRF_UICR_BOOT_START_ADDRESS     (NRF_UICR_BASE + 0x14)  
#define BOOTLOADER_ADDRESS                     *((uint32_t *)NRF_UICR_BOOT_START_ADDRESS)
#endif

Hi Planas,

I have reproduced and confirmed the issue here.

It was the issue with pstorage, due to the fact that we don't rearrange the pstorage data properly when the bootloader is installed. And pstorage will try to overwrite the area the bootloader already occupied.

The fix is to move the pstorage data area under the bootloader if the bootloader is existing on the flash (bootloader address is written in the UICR).

What you need to is to replace

#define BOOTLOADER_ADDRESS        PSTORAGE_FLASH_EMPTY_MASK

with

#define NRF_UICR_BOOT_START_ADDRESS     (NRF_UICR_BASE + 0x14)  

#define BOOTLOADER_ADDRESS         *((uint32_t *)NRF_UICR_BOOT_START_ADDRESS)

in file pstorage_platform.h in your application source code.

I will report this issue internally. It will be fixed in the future release of the SDK.
