Dear Sir,
I am trying to configure LPC2362 as USB HOST at port 1. I am using FAT16 file
system pen drive as an USB Device. As per OHCI specs, I configured LPC2362 Host
Controller. I am able to detect the device i.e. getting CCS
(CurrentConnectStatus) bit =1 and CSC (ConnectStatusChange) bit = 1 of
HcRhPortStatus[1] register.
The problem I am facing is that setup token packet is not getting transmitted.
The registers HcControlHeadED and HcDoneHead both are empty. They point to the
physical address of current endpoint descriptor and last transfer descriptor
added to the 'Done' queue respectively. Please, suggest me what is missing.
Steps that I am following:-
1. I had configured LPC2362 Port pins as per USB PORT 1 and assigned memory to
all buffers of Host controller (Transfer Descriptor buffer, end point descriptor
buffer, HCCA etc.)
2. I had enabled 3 USB HOST INTERRUPTS [WDH, RHSC, MIE (Master interrupt
bit)]
3. As soon i connect my PEN DRIVE to the Port 1 of USB, I received the
USB_HOST interrupt of LPC2362 & MIE; RHSC interrupts of the Host controller
4. I also got CCS (Device Connected bit) set of HcRhPortStatus1 of Host
controller which tells that device is connected
5. After completing the Port reset process of HC, I tried to Read first 8
bytes of device descriptor using GET_DESCRIPTOR command
6. I filled the Transfer Descriptor Buffer and linked it with the Endpoint
Descriptor as per its format in OHCI specs
7. I copy the address of Endpint Descriptor into the HCControlHead register &
sets the CLF bit of HcCommandStatus & CLE bit of Hccontrol registers
8. Then I am waiting for the Writebackdonehead WDH Interrupt of
Hcinterruptstatus register. But not getting a single interrupt.
9. Then I checked HcControlHeadED, HcControlCurrentED and HcDoneHead register
of the Host controller. They all are empty.
Thanks & Regards,
Ranjeet Gupta

LPC2362 USB Host Not Sending Setup Token Packets

Where is your HCCA and TD header located?
Use USB RAM start at 0x7FD0 0000. Try NXP's
USBHostLite example before working on your own.

TDTail = (volatile HCTD *)(HOST_BASE_ADDR+0x110);
EDCtrl = (volatile HCED *)(HOST_BASE_ADDR+0x120);
EDBulkIn = (volatile HCED *)(HOST_BASE_ADDR+0x130);

TDBuffer = (volatile USB_INT08U *)(HOST_BASE_ADDR+0x150);
FATBuffer = (volatile USB_INT08U *)(HOST_BASE_ADDR+0x1D0);
UserBuffer = (volatile USB_INT08U *)(HOST_BASE_ADDR+0x1000);
/*
