SDK 15.3.0 missing bootloader definitions for NRF52832_XXAB (QFAB)

[Bruno Randolf]

I have been working to get the secure_bootloader examples to run on the NRF52832_XXAB (QFAB with 32kB RAM and 256kB Flash).

Apart from the fact that I had to change the RAM and FLASH sizes and bootloader_settings_page and mbr_params_page locations in the linker script:

FLASH (rx) : ORIGIN = 0x38000, LENGTH = 0x6000
RAM (rwx) : ORIGIN = 0x20003278, LENGTH = 0x4d88
mbr_params_page (r) : ORIGIN = 0x0003E000, LENGTH = 0x1000
bootloader_settings_page (r) : ORIGIN = 0x0003F000, LENGTH = 0x1000

The definitions of BOOTLOADER_SETTINGS_ADDRESS and NRF_MBR_PARAMS_PAGE_ADDRESS in the SDK are missing for NRF52832_XXAB, i needed to add the following patch:

HI Bruno, 

Thank you for the bug report and patch. I will report this internally!

Best regards

Bjørn

[Bruno Randolf]

The change is not in SDK16 - any reason?

[bjorn-spockeli]

 The XXAB variant is not officially supported in the nRF5 SDK v15.3.0 and v16.0.0.
