Hi,
I am facing an issue with a request of USB bulk transfer from a linux host to
DaVinci DM6467 EVM. I used USB_to_PCI_loop_test.c as a base and tried to modify
for sending a bulk transfer write request. I get an error status from following
snippet of code:
bulk_transfer.ep = 2;
bulk_transfer.len = sizeof(USB_TEST_DATA);
bulk_transfer.timeout = 10;
bulk_transfer.data = &USB_TEST_DATA;
status = usbdev_ioctl (fd, dev->ifnum, USBDEVFS_BULK, &bulk_transfer);
printf("Bulk status 0x%x\n",status); ----> I get 0xfffffff and DaVinci EVM does
not get any data.
Is there any example code for implementing USB bulk transfer from a linux host to DaVinci ?
I have searched the web but could not find anything.This is a very simple
thing to perform data transfer so my understanding is there must be something
available to perform this. The test code uses test ioctl number which are not
very useful when sending actual data.
Thanks,
Neeraj
