Hi, Iam trying to integrate TUSB3410 UART with PowerPC based SBC in which Iam running Linux Version 2.4.32.
I used the source files downloaded from http://gate.brimson.com/downloads/ As Iam using 2.4 kernel, I have selected ti_usb-1.0-1.src.rpm and used the files ti_usb_3410_5052.c ti_usb_3410_5052.h ti_fw_3410.h ti_fw_5052.h ti_usb_serial.c ti_usb_serial.h I could compile it successfully.. But When insert the device..its failing in function "static int ti_startup(struct usb_serial *serial)" in ti_usb_2410_5052.c file... Iam getting the following error : May 15 23:52:47 crind30 user.warn kernel: usb.c: selecting invalid configuration 2 May 15 23:52:47 crind30 user.err kernel: ti_usb_3410_5052.c: ti_startup - cannot set configuration I have the following doubts: 1. When I go through ti_fw_3410.h, there is a comment "/* firmware image length excluding header, little endian */".... Which means the fw image is for little endian based processors.. But Iam using PowerPC which is Big Endian. How can I get the binay image for big endian? 2. I could not understand why there are 2 configurations in this device and what they really mean? .. As I see in ti_usb_3410_5052.c the ti_startup is failing when it actually switching the configuration to TI_ACTIVE_CONFIG. The related code is pasted under: /* so we have 2 configurations; if the first is set, */ /* switch configurations */ if (dev->actconfig->bConfigurationValue == TI_BOOT_CONFIG) { status = usb_set_configuration(dev, TI_ACTIVE_CONFIG); if (status) { err("%s - cannot set configuration", __FUNCTION__); goto free_tdev; } serial->interface = dev->actconfig->interface; /* reconfigure usbserial */ ti_usb_serial_free_urbs(serial, 1); status = ti_usb_serial_alloc_urbs(serial); if (status) goto free_tdev; if (serial->num_bulk_in != (tdev->td_is_3410 ? 1 : 2) || serial->num_bulk_out != (tdev->td_is_3410 ? 1 : 2) || serial->num_interrupt_in != 1) { err("%s - wrong number of endpoints", __FUNCTION__); status = -EINVAL; goto free_tdev; } } Please suggest..
