S110 8.0.0 DFU example on nrf51822

[Mathias]

Hi,

I am having problems using the the dfu_dual_bank_ble_s110_pca10028 example on a nrf51822_xxAA device.

I have changed the memory ares to:

IROM 1: 0x3C000, 0x3C00 IRAM 1: 0x20002C00, 0x1380 IRAM 2: 0x20003F80, 0x80 (NoInit)

Altough i become Linker Errors:

._build\nrf51422_xxac.axf: Error: L6406E: No space in execution regions with .ANY selector matching arm_startup_nrf51.o(STACK). ._build\nrf51422_xxac.axf: Error: L6407E: Sections of aggregate size 0x800 bytes could not fit into .ANY selector(s).

The preprocessor definition has been changed to BOARD_PCA10001 as well.

Thanks in advance.

I solved the problem myself by reducing the stack size to 255 in arm_startup_nrf51.s, hope this will be enough for the bootloader application but think so?

Additionally I had to add:

#define PSTORAGE_RAW_MODE_ENABLE

in pstorage_platform.h.

Hi Mathias, I am having the same issue. Would you mind explain the reason behind adding #define PSTORAGE_RAW_MODE_ENABLE? I read the Raw Mode section here but I still am not very clear on how Raw Mode helps. Also, are there any concerns when decreasing the Stack so much?
