Hi, I want to enable 3.3v on extension board.

About this, User manual says :

The 3V3 power line might be disabled if you don’t use the SD card as well. Please use the

“sdc_init” command to enable the 3V3 on the extension bus.

 

At this point, sdc_init command means SDCardDriver_Initialize() ?

Hello Kim,

That depends on the version of the XDK-Workbench you currently use. It is correct, that you can enable the 3.3 V supply pin on the extension bus with the function call sdc_init() on the XDK-Workbench 2.0.1.

With XDK-Workbench 3.0.1+, the function call changed to Board_EnablePowerSupply3V3(EXTENSION_BOARD). For more information, please refer to section 4.2.2 in the latest version of the general information guide, which you can find here.

Please note that you need to make a small adaption in the makefile to make the function call work. Open the makefile of the project and in line 20, below export BCDS_XDK_INCLUDES = \ insert the following command:

-I$(BCDS_APP_DIR)/../../SDK/xdk110/Platform/BSP/source/

Otherwise the compiler will throw an error because he cannot find the interface BSP_BoardShared.h.

Please let me know if that was helpful and do not hesitate to ask if you have further questions.

Kind regards,
Franjo

Hello,

Thanks Franjo, you help me in the right direction, but I had to modify the inserted line to :

-I$(BCDS_BASE_DIR)/xdk110/Platform/BSP/source/

Because my APP_DIR is nowhere near the SDK dir.

I hope this will help someone.

Kind regards
