about DFU on nrf51822 aa (use sdk v11,s130)

[Liu]

Hi.... I have a problem when i use dfu_dual_bank_ble_s130_pca10028 in sdk v11 on my board. cpu is nrf51822QFAA.it seems reset all the time. using keil debug, it's wrong on this point

dfu_init() in bootloader_dfu_start()

 in dfu_init()  there is a error on this statement 
err_code = pstorage_register(&storage_module_param, &m_storage_handle_app);

 go on.

in pstorage_register()

if (m_next_app_instance == PSTORAGE_NUM_OF_PAGES){return NRF_ERROR_NO_MEM;}

PSTORAGE_NUM_OF_PAGES is defined 1, and i find the pstorage_register() is called onec before in bootloader_init();
is there wrong steps i using the example?

Have you edited the ROM/RAM settings? The SDK examples are by default compatible with QFAC variants, i.e. 256kB Flash and 32kB RAM. The QFAA variants only have 16kB RAM and this must be taken into account.

thanks for your reply. yes, i modify the ram setting as follow

• IRAM1 0x20002000 size 0x1F80
• IRAM2 0x20003F80 size 0x80 noInit

and the flash equal

Try setting PSTORAGE_NUM_OF_PAGES to 2.
