minidriver download和application download

[YaTr_3516311]

Hi,

我想做通过MCU 更新蓝牙固件的功能,所以抓了一下WICED MODULE programmer的流程。发现会有两个部分的downlaod。先是minidriver的download。然后是application的download.

1. minidriver的downalod是必须的吗?

2. application downlaod的数据是.hex。那么minidriver download的数据从何而来？即B处的数据从何而来

Hi,

1) Minidriver download is recommended for flash download.

It is NOT NEEDED IF THE ROM FIRMWARE CAN HANDLE NVRAM ACCESS (but most often the minidriver is required. for example for 207xx, 208xx devices).

2) The minidriver file will be available in path

for MODUS: C:\Users\....\ModusToolbox_1.1\libraries\bt_sdk-1.1\components\BT-SDK\208XX-A1_Bluetooth\platforms\minidriver-20819A1-uart-patchram.hex

for WICED: C:\Users\draj\Documents\WICED-Studio-6.4.0.61_pub\20706-A2_Bluetooth\platforms\CYW920706WCDEVAL\uart.hex

Thanks,
