Right I had already added the missing statements. I found my problem yesterday, apparently the 3.3V and 2.5V pins don't work or don't supply enough current. I was able to make it work by connecting my UART module to an external power supply.
Should I initialize the power pins on the gateway, or is there a max current that can be supplied by it?
I found the way while looking at the definition of SDCardDriver_Init(). The following statement enables the 2 power pins on the gateway:
as I understand you try to supply an additional external UART module to receive the data from the XDK. Am I right so far?
If this is the case it depends on the power consumption of your module. The 3.3 V and 2.5 V pins have a maximum output of 100 mA. If your UART module requires a greater amount of supply current, your choice using an external supply source should be the way to go. Otherwise you can use them and activate via PTD_pinModeSet() as you already mentioned.
Please tell me if this helps you and do not hesitate to ask if you have further questions.
Kind regards, Franjo
You're correct. My module draws up to 50 mA every few minutes so it is fine.
Thanks for your help!
I am glad to hear that this fits for your purpose.
