SDK6.1 device_firmware_update\bootloader example. - Compile Error using IAR

Question

SoftDevice : S110 7.1 
 
 
 SDK 6.1 
 
 
 Using IAR 7.1 
 
 
 Example : device_firmware_update\bootloader 
 
 
 Board : PCA10001 
 
 
 /**********************/ 
 Hi, I was trying this example. 
 I tried with Keil uVision 5. Thanks to the prebuild project file, it worked on Keil. 
 However, I mainly use IAR. While migrating the example, it had compile errors. 
 
 
 The "bootloader_util_arm.c" had problem. 
 I tried to search about this "__asm" and the difference between the Keil project settings. 
 However, I couldn't find it. (Maybe it is due to lack of knowledge about assembler or linker.) 
 So, the questions are, 
 
 what other settings are needed? 
 
 The current setting follows like these. 
 
 Preprocessors : ICCARM 
NRF51
BOARD_PCA10001
BLE_STACK_SUPPORT_REQD
BOOTLOADER_BANKED 
 (I erased the "DEBUG_NRF_USER" on purpose.) 
 
 Are there similar examples like this in the SDK 7.2? 
 
 What are the name of the examples? 
 -Regards, Mango922

The assembly syntax is only compatible with Keil. However, IAR (and GCC) support was added in SDK 8.1.0. I think the alternatives are to either backport the assembly routines to your existing bootloader or migrate to the latest version, I would suggest the latter if possible. 
 That said, as you may know, SDK v.7 and later are configured for the new DK kits which targets the 32K ram variant ( overview of chip variants) . Thus, minimum change required to run on on PCA10001 (assuming 2nd rev IC) is to change the RAM allocation in the linker script.
