It's solved！

I have tested it on WICED SDK 6.2.1 and it build success.

Or you can create a new folder under 20719-B1_Bluetooth\platforms\ . Then copy the file 20719_OCF.btp from 20719-B1_Bluetooth\platforms\CYW920719Q40EVB_01 to it.

Additional, could you let us know why you need a large array in your application? Will the data in the array be changed in the application?

A high speed device outputs the data about 300KBytes in 30ms, CYW20719 will receive the data and send it in 3s.

So large size RAM is critical.

Is it possible to place the profile library code in flash, as "Execute-in-Place (XIP) Application Support Guide.pdf" said?

Hi XinghaoZ_26

Do you have any conclusion?

As the document "CYW20719: Execute-in-Place (XIP) Application Support Guide" says, please configure the ConfigDSLocation based on the APP XIP Size. Then addd APP_XIP=1 to enable the XIP function.

[JiZh_4619191]

"APP_XIP=1" can only place APP in flash.

But can not place the profile library code in flash.

How about the profile library code?
