hi, i am working on a project that in it i need to write and read sectors in sd card, i decide to use keil File system lib with mci driver but i have problem to write sector in sd card but reading is ok. i use below code to initilize sd card:
if (finit ("M0:") != fsOK) { // Initialize File System return 0; // Exit if failed } id = fs_ioc_get_id ("M0:"); // Get ID of media drive if (sdcard_drv_id < 0U) { return 0; } // If ID is invalid exit status = 0U; if (fs_ioc_device_ctrl (id, fsDevCtrlCodeControlMedia, &status) != fsOK) { return 0; // Exit if failed } if (fs_ioc_lock (id)) { // Lock media for USB usage return 0; // Exit if failed } st = fs_ioc_write_sector(id,0,buf,1); if(st != fsOK) return 0;
when i call fs_ioc_write_sector in above code it returns FsError(0x01) but when reading sector it work correctly. can any one give me an advise to solve that??

hi mohamad, i am using keil middleware file system under CMSIS:MCI driver, and i did n't find file that you point, also my mcu is lpc1788. after i programming keil usb file system example to my board, i notice that this example like my code can not write sector on sd card and writing done with fsError !!!! may be problem is keil side and library has a problem ???? i am still searching for solution and i can find problem.
after some hours of Paddle i noticed that fs_write sector write data on sd card(i can see writed data on hex editor when atach it to computer) but it return FsError !!!!!!! i wondered so, what is problem??
I uploaded file system files from outside and used it separate as any other c file that is why i can control my programs more easy check FATFS by chan files and try to implement it outside keil lib
don macki, I suggest that you take a look at your MCI driver and investigate if COMMAND_TIMEOUT/ERROR or TRANSFER_TIMEOUT/ERROR events are returned at some point.
