hi friends, experts!
I am using LPC4078 evaluation board and I can read/write SD card in text file and binary file without any problem.
Now I try to work with XML file format. I found a lot of XML open source parser in the internet but I hit a problem is:
- The open source XML use standard C library to such as: fopen() to open a file, fread() to read, fwrite() to write to file.Example:
fp = fopen("filename.xml", "w");
mxmlSaveFile(tree, fp, MXML_NO_CALLBACK);
fclose(fp);
- While I am using library developed by NXP. Example:
FRESULT rc;
rc = f_open(&Fil, "HELLO.xml", FA_WRITE | FA_CREATE_ALWAYS);
rc = f_close(&Fil);
Even compiling ok, the CPU will hang when hit to function fopen() in XML parser code.
Any help is appreciated!
