how can i configure the SD card as write protected on the board to be detected by PC through USB Device mode(MSC Mode)

Unable to recognize USB port as a device(virtual com port) when connected to PC.

I tried configuring the SAI peripheral in STM32F469. After initialization I was unable to get any clock outputs including MCLK.

Please help me in selecting the micro controller for my projet

We interfaced sd card on SDIO lines in 4 bit mode. While recording and playing audio files,we observed "ti tik tik" noise in the line. We are using external codec on i2s line for recording and playing. Kindly let us know how to resolve this issue,
