RED LED blinks continously and uC hangs...Why...??
While performing some write and read operation from and to the SD card sometimes the RED LED blinks .. Can anyone explain the reason why with the solution also.. Also there is no ERROR message on the Tera Term also...??
Be the first to answer this question.
Need more info, such as what platform(PCB) are you using, what LED# is blinking, and what sample code are you loading?
To get output on TeraTerm ensure you compiled with any debug enabled (In many samples need to change appropriate #define from 0 to 1)
posted by Paul Russell 10 Dec 2014I am trying to send some data from SD card to the server using AT commands on gsm sim 900 module and I am using FRDM K64F evaluation board and I m running this function in a thread. As soon as FTP thread starts after two loops ( one loop send 1000 character at one time in FTP session) the RED led near micro sd card on uC starts blinking and the uC hangs.. I dont know why...??
