RE: DFU Dual Bank Example with PCA10001

Is there a reason for dividing into 2 RAMs?

I'm using SDK 7.2, S110 7.1, and IAR 7.1 with the PCA10001 Board (Revision 2 MCU).

Unfortunately I can only set one RAM part at the linker script file (.icf file).

Also, how can I set "NoInit" in IAR?

I cannot find a way.

At least this thread should get you started on the debugging.

A new bootloader feature was introduced with SDK version 7 which includes init packets which are sent from the central to the device before the actual application firmware image is transmitted. IRAM2 section is needed for this init packet data.

Try to define the RAM sections similar to the bootloader example does in SDK 7.2.0 but for 16kB RAM instead of 32kB RAM:

IRAM1:   Start: 0x20002C00   Size: 0x1380
IRAM2:   Start: 0x20003F80   Size: 0x80

and check NoInit for IRAM2.
