Content originally posted in LPCWare by whoms on Sat Apr 28 17:51:31 MST 2012 I've tested nxpUSBLib 0.94 on LPC1788,LPC1850. USB flash disk is directly sector wrote using USBHost_Mass_Storage . The speed is only 150KB/s. And I've verified the LPC1850's USB0 host is set at High Speed mode. LPC1788 is running at 108MHz,USB CLK=48MHz LPC1850 is running at 167MHz,USB CLK=480MHz
Can anybody give an explanation ? How to improve the USB flash disk writing speed to about 1MB/s on LPC185x or LPC435x ?
