I encountered some problems when implementing the USB MSC function.
This CSL_USB_MSC_dmaExample implements USB MSC functionality.
The current CPU frequency is 100MHz, and the SD clock frequency is 25MHz.
The reading speed is about 2MB/s.
Write the card at a speed of 260kB/s.
1. How to improve the read/write speed?
If a large file (greater than 10MB) is written into the file, the file is suddenly terminated before the writing is complete.
However, it is sometimes possible to write a 40MB file without a hitch.
2. How can we achieve the stability of writing files?
