Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE
Dear all,
we are using TMS320F28377D control card. We are trying to develop some system around SD card. We started with Control suit SD card related project. We are trying to read a text file from SD card & we are trying to write same data in new text file on SD card.
We developed necessary functions & we are facing following problem.
If I use file "READ.txt" to read data from file & if file "WRITE.txt" to rewrite same data then
1. If I generate new file "WRITE.txt" on SD card through my program, then file gets created but no data is getting written. It is remaining blank.
2. If I create new file "WRITE.txt" on SD card using Windows PC and connect that card to control card, then no data is getting written. Again It is remaining blank.
3. If I create new file "WRITE.txt" on SD card using Windows PC and write some text data in file say 20 characters then on connecting that card to control card, only first 20 charters from file"READ.txt" are getting overwritten in file "WRITE.txt" & rest data is lost.
Can some one please let me know what can be the problem.
We have developed similar system for USB memory & it is working fine.
with Best Regards
Abhijit Kelkar
