nRF51822 library not compiling

I've created a small program to test some functions but can't get it to compile. I've include the BLE library as I want the BLE stack running during my tests.

Using all the latest versions of BLE_API, nRF51822, and mbed-src

/* power consumption testing
#include "mbed.h"
#include "BLE.h"

#define LED_INTERVAL    2

BLE  ble; //BLE device object

Timeout alertTimer;
DigitalOut led(LED1);

void timeoutCallback(void)
    led = ~led;
    alertTimer.attach(&timeoutCallback, LED_INTERVAL);

void disconnectionCallback(const Gap::DisconnectionCallbackParams_t *params)
int main() {
    alertTimer.attach(&timeoutCallback, LED_INTERVAL);
    while(1) {
        ble.waitForEvent(); // let the library manage power and stuff. 

When I compile the following error appears.


Error: Struct "<unnamed>" has no field "NRFFW" in "nRF51822/source/nordic_sdk/components/libraries/fstorage/fstorage_config.h", Line: 85, Col: 49

This is a line in the fstorage_config.h file in the nordic SDK components. Is this possibly a change in the SDK not updated in the mbed library?


Hi Andrew,
I could compile your program without error.
I tried three diffrent boards, TY51822r3(Switch Sinence), nRF51822 & Nano(RedBear Lab.).
Those three are fine (only compile not run) for me.
In addtion, I had some experiance to get the error in the past and modified the file as follows.


static __INLINE uint32_t fs_flash_page_end_addr()
#if 0
    uint32_t const bootloader_addr = NRF_UICR->NRFFW[0];
    uint32_t const bootloader_addr = NRF_UICR->BOOTLOADERADDR;
    return  ((bootloader_addr != FS_EMPTY_MASK) ?
             bootloader_addr : NRF_FICR->CODESIZE * FS_PAGE_SIZE);

NRFFW[0] is same address with BOOTLOADERADDR (Set union structre).

I also tried the compiling with the RedbearLab nRF51822 target, but got same error. Then I made change as you suggested and error dissappeared, although several warnings about incompatible parameter rypes still remain. I don't understand why this has appeared now, but is not in my other projects using same target.
