casting pointers

[Stanislav Silnitskiy]

Hello!

I've bumped into the issue with casting...

main.c:
static ble_gap_addr_t addr0;
static uint16_t *p_host0;

int main(void) {
    p_host0 = (void*)&addr0.addr[0];

works fine, but...

beacon.c:
static ble_gap_addr_t addr1;
static uint16_t *p_host1;

void init_beacon(void) {
   p_host1 = (void*)&addr1.addr[0];

hungs in assignment when I call init_beacon() from main()

Where is rake?

It must be memory alignment issue.

I tried to avoid editing SDK, but the only plausible solution I see, is to switch places of struct. members and add alignment (not sure, either it is really required):

ble_gap.h:

/**@brief Bluetooth Low Energy address. */
typedef struct
{
  uint8_t addr[BLE_GAP_ADDR_LEN];       /**< 48-bit address, LSB format. */
  uint8_t addr_type;                    /**< See @ref BLE_GAP_ADDR_TYPES. */
} ble_gap_addr_t __attribute__((aligned(16)));
