SD Card boostPack question

Hello Shan,

When I clicked to the 43oh page where this boosterpack was available for sale, there were several links to support areas including a getting started block and a support forum. From what I saw, most of these centered around using the boosterpack with the MSP430 launchpad, but it should be possible to use this code as reference in developing/porting the code for the TM4C.

With that said, there should be some basic commands that can be sent to the SD card to check that it is communicating. These should be covered in the tutorials and information on the 43oh website or perhaps in the datasheet for the type of SD card you are using.

Another point to check is to put a scope on the communication lines going into the SD card socket and/or check the supply lines on it. This should confirm if all the proper signals are there and HW is correct.

Hello Shan,

Yes, this is the page I went to. On it you will find the following links:

totorial in the 430h blog: 43oh.com/.../

Code is available in the 43oh Forum: forum.43oh.com/.../

Also there is another link to a wiki page that seems broken.

I would suggest you have a look in those locations to see if they can help you get started. Also, I would double check your hardware to make sure you have the proper connections. This can be done by checking signals using active SW or by simply using an ohmmeter to check continuity. There are only a few lines so this shouldn't take too long to insure proper connectivity.

Thanks, Chuck, I think I will choose the ohmmeter.
