PSoC 5, 3 & 1 MCU

 Hi all,

   

Recently I am developing a bigger micrcontroller project with many long codes. Basically, I am using PSoC 5 CY8CKIT-050LP to interface a SD card module (ALFAT OEM Processor: https://www.ghielectronics.com/downloads/ALFAT/ALFAT_SoC_Processor_User_Manual.pdf). With the integrated UART module block. I don't have any problem with any external modules being connected to the PSoC5 (Those include: XBee and several analogue sensor).

   

But until recently, sometimes my system just freeze halfway even though the codes are correct as I tried before. Funnier thing happens when I try to plug/unplug the SD card, it sometimes do work or freeze halfway!

   

Since I got no syntax/programming error before such problem occur, my concern lies on hardware design/circuitry problem. But thinking my codes are quite long, I am wondering whether such huge programming code cause the problem?

   

Anyone of you face the similar problem before?

In your code do you have any blocking statement or something which will check for the SD Card or wait there?
