Hello,
I am developing an application using keil's RL-USB library to turn the microcontroller into a USB host controller.
I use the keil's sample: E:\Keilv5\ARM\Boards\Embedded Artists\LPC1788-32 Developers Kit\RL\USB\Host\MSD_File
I have used USB2 as the host. I change the HOST controller in USB_Config.c to USB HOST 1. but i recive this error: .\Obj\MSD_File.axf: Error: L6218E: Undefined symbol usbh1_hcd_ohci (referred from usb_config.o).
So you are doing "programming by trial and error", and then posting all errors you get to this forum?
keil sample have error
what means "programming by trial and error"!!!!!!
You change things in a random attempt to solve the problem rather than understand what the error is telling you.
