I am using cora z10 to read data from XADC and stores it in SDcard, using a baremetal application. I am reading data at a rate of 1Khz from xadc and write this adc data in sdcard. I have a buffer of 1000 bytes and when its filled then i write entire buffer to SDcard.
The problem is i am not able to append data on opened file. I am using f_write to write data and f_open in FA_WRITE mode. I don.t want to always open and close file as this operation takes around 5msec. Is there any other way to do so? How can i append data to a opened file?

i get an error 'FA_OPEN_APPEND' undeclared (first use in this function). I have included ff.h in header. I noticed that FA_OPEN_APPEND declaration does not exist in ff.h.
