Hi all, I try to enable the USB host controller on a mpc823 (TQM832L-Board). The CPU is a mpc823e (PPC823EZTnnB2)
1. I collected and read all information from the web and this mailing list. 2. I got Brad Parkers's m8xxhci driver rev. 2 from heeltoe.com 3. I did some modifications in the driver source. - USE_TIMER1_FOR_SOF - USE_PA4_CLK4 4. I disabled the POLL_FOR_HUB code If I boot the target, all seems ok. If I connect a usb keyboard to the target, I get theese messages (the keyboard contains a usb 5 port hub): hub.c: USB new device connect on bus1/1, assigned device number 7 hub.c: USB hub found hub.c: 5 ports detected hub.c: USB new device connect on bus1/1/4, assigned device number 8 usb.c: USB device driver not accepting new addres=8 (error=-110) usb.c: USB new device connect on bus 1/1/4 assigned device number 9 input0: USB HIDBP Keyboard 046a:0001 on on usb1:9.0 If I press the keyboard - nothing occurs ... I dont't know, why the driver needs two tries to recognize the keyboard. The TQM823L-Board uses a Philips USB Transceiver and I did not insert the delay gates between the mpc and the transceiver. If I remove the keyboard, the following messages occur: usb.c: USB disconnect on device 7 usb.c: USB disconnect on device 9 rh_port_enable(0) If I connect a Thunderbird 4-Port USB HUB, the following messages occur: rh_port_reset(1) hub.c: USB new device connect on bus1/1, assigned device number 10 usb.c: USB device not responding, giving up (error=-110) or rh_port_reset(1) hub.c: USB new device connect on bus1/1, assigned device number 2 hub.c: USB hub found hub.c: 4 ports detected hub.c: Unable to get hub status (err=-110) hub.c: hub configuration failed for device #2 usb.c: USB device 2 (vend/prod 0x3eb/0x3301) is not claimed by any active driver Now - does the driver work or not or partially and do I need to insert the delay gates between mpc an usb transceiver ?
