[U-Boot] USB Device Port not working in MPC8280 PowerPC
Dear All, am facing problem on writing USB device port driver for MPC8280,when i connect it to the host PC through USB cable .device descriptor is happening host is setting the address but device configuration is not happening properly...it hangs there in USB busy handler.
below is the output of the snippet in hyperterminal for usb debugging
Debug statements
GetDescriptor request length = 0x40 Device Descriptor... bd status = 3ec0 In TX USB event register = 108 Recieved PID token = 0x3cc0 USB:SetAddress 2 bd status = 3800 bd status = 3ac0 In TX USB event register = 108 GetDescriptor request length = 0x12 Device Descriptor... bd status = 3ec0 In TX USB event register = 109 Recieved PID token = 0x3cc0 In USB_BUSY HANDLER : 0x108
it hangs in usb busy handler , am feeling data pid toggling may be the issue.
please help me out to sort this issue....let me know if any codes are available for USB Device & USB Host testing for MPC8280.
am testing in FreeScale Code Warrior IDE
waiting for the reply ASAP
Regards, Gurumurthy

Which exact version of U-Boot are you running?
Best regards,
Wolfgang Denk
U-boot 1.3.1 ELDK 4.2
currently debugging in Code Warrior IDE. i have taken device port code from u-boot i.e mpc8xx_udc.c & modified to suit mpc8280.

Curent code is either v2009.06 or top of tree from git repository.
And no, AFAIKT there are no USB drivers for the MPC8280 in U-Boot.
But why are you asking? I thought you had somethin written yourself - didn't you ask about problems with USB in U-Boot? So you must have had some driver added to U-Boot?

Dear Sir, sorry for the miss quote. i have written the code for USB device & USB Host from taking reference code of U-boot.
current version is ELDK version 4.2 ppc_6xx: Build 2008-04-01
