DFU BLE on singlebank

[steven]

Dear all: same as this issue: devzone.nordicsemi.com/.../use-dfu-to-update-ap-over-ble-single-bank

it seem same as my way that modify modify "dfu_dual_bank_ble" target . only modify dfu_double_bank.c to dfu_single_bank.c. Then get the error (see the attachment file,IMG_0050[1].PNG)) and i found it have some error

1. conn_params_negotiation () it can't setting the connect params
2. bootloader_settings_save () A.the call bootloader_util_settings_get(&p_bootloader_settings); the p_bootloader_settings all 0xFF. B.when call ble_flash_page_erase() function , it will be block.

how to solve it ?

Development Environment: nrf6310 DK Board, BLE SDK , vsdk_4.4.0 SD : v5.2.1

hi, I trace the code,and when ble_flash_page_erase() function , it will be failed to erase flash then be reset system.

it is bug when ble run to write flash page. because when the dual bank ble DFU is correct. same as my Previous issue about FLASH : devzone.nordicsemi.com/.../halt-flash-write

attatchments files: my device_fireware_updates.rar project (select the single bank ble target)
