[メモ]BLENano(nRF51822)のSoftDevice使用時のフラッシュメモリマップ(nRF51-SDK10)

Last updated at Posted at 2016-02-06

SEGGER J-LINKが使えたので、nRFGo Studioを使って、フラッシュの配置を確認。
Region0はNordic謹製のBLEプロトコルスタックのSoftDevice。Region1はApplicationを書き込む。
のちほどRegion1-Addressを使用する。
ところで、BLE Nanoは、V1.5とV1.0があり、nRF51822のARM Cortex-M0コア、Flash 256kBは同じで、RAMが32kB(v1.5)/16KB(V1.0)と。ちがう。

SoftDevice > S110 S120 S130
Region0-Firmware S110_nRF51_8.0.0
(Id:0x0064)
120_nRF51_2.1.0
(Id:0x006b)
130_nRF51_1.0.0
(Id:0x0067)
Region0-Size 96KB 116KB 112KB
Region1-Size 160KB 140KB 144KB
Region1-Address 0x18000 0x1d000 0x1c000
