Hi I am using LPC4357 and working on USB host and FTP. MSD via USB0 is storage for FTP server.
here I have a problem with USB0_CASZ("File System Cache") value
when I set it to 16KB it so fast in read progress(about 7MB/s via FTP). but for writing at the end of file Ethernet connection will lost and in debugging I couldn't find what happened on LPC4357? (MCU is running under library functions and never stop on my own code but it is running)
if I set USB0_CASZ to 4KB it will works perfectly but speed will be about 4MB/s for write and read too.
Do you have any idea to have maximum speed and reliability at the same time?
