I am testing USB host in FRDM-Kl46Z REC C board. I have loaded usb_host_freedom.srec from FRDM-KL46Z_QSP->Precompiled Examples. I have connected pendrive in the USB port but no files created in pendrive or no led indication. What will happen if i flash usb_host_freedom.srec file and how to test it. I have shorted J7 and J16 and R16 mounted in board. I want to test USB MSD application in FRDM-Kl46Z.
