Good Morning!


I am using LPC1768FBD100 chip, and using USB host for my project. I am using two timers (1ms and 250us). The priority of USB is higher than timers. I am trying read information from USB inside timer (1ms specifically) but it is not working. Is important to know that I am using file system to read/write USB information. Is important to know too that I am opening the file out of the timer and only reading the content of file inside timer. In this process, when function  FSUSB_DiskReadSectors is called the process is waiting for USB forever. If I open and read information from USB out of timer, everthing is working fine.


Someone has this problem?
