Hi, can any one plz help me to solve fatfs read problem?
I am using Cortex-M3 luminary lm3s6965 controller. My application is such that I am writing 100-150k data(1024 bytes at a time; i.e. using for loop), in single .csv file, in 4GB micro SD card using fat16. and it is working perferctly.
Bt when I am trying to read data from sd card(1024 bytes at a time), then it will read data upto 65535 bytes and then it gets hang.
So can i read complete 100-150k data from sd card.
Could any body help? Thanks in advance...
Well where's the code doing the actual reading? And why would you keep opening/closing the file? Interrupts disabled? Are you polling in you SD read code?
My problem is still not resolved to read sd card having file size more than 64K.
I have tried one more experiment: If my file size is >64K, then i read only 64k data continuosly and that code works fine.
So what is real problem? Plz help.......... Give me some sample code...
