HDK Connectivity Code on 3137 HDK - SD Card Code on SPI3 vs. SPI2?

John Westmoreland43

Hello,

Took a look at the HDK Connectivity example for the 3137 HDK which is posted on that wiki.

From the schematic, the SD card is on SPI2 but in the example code that is on SPI3 - I guess this could be due to board change.

But, does that demo really do anything? I tried adding a read_block command that returns an error.

Thanks in Advance,

Hi John,

This test case is only connectivity test. SD code checks the reset command only, does not do read/write/erase operation which requires FS. Please find HDK SD card demo project in this forum as reference.

QJ,

OK - are you saying the HDK SD Card demo project in this forum has an FS?

I have searched - can you please point me to the correct demo project? SPI2 is correct also, yes?

Thanks,
John W.

Hi John,

SD card uses SPI2 on HDK. Enclosed is the CCS project for SD card on HDK.

QJ,

OK - thanks for posting that. I couldn't find that on my own for some reason.

I will let you know how this goes.

Wow - I have a weird problem now. I changed the project to use the 3137 and now I can't connect to the board anymore. I will start a new thread on this one.
