In loading the K40 example from Future class TWR-K40X256_Quick_Start_Demo it seem to work fine except for I get "Error installing communication handle." for the SDCard. fopen returns NULL. Has anyone seen this?
Sorry I was using the IAR example that they had us run. Unless you have a serial port running you never will see the error message. So i just now noticed it. I could not get the sdcard Shell routines to work.
I am using the IAR example that we got during the one day class.
As far as I remember, the bugs relating to sd card has been fixed in mqx3.8.
