I am returning to my driver for the Alphi Technologies AD8
Previously I asked about downloading a file and I added the following code:
if(it->options[0] && it->options[1]){
size = it->options[1];
dev->private->firmware = kmalloc(size,GFP_KERNEL);
if(copy_from_user(dev->private->firmware,
(unsigned char *)it->options[0],
size)){
printk("comedi_: usbdaqdt%d: ptr to firmware
invalid\n",
index);
ret=-EFAULT;
return ret;
}
I have now upgaded from comedi-0.7.66 to comedi-0.7.68
The copy from user is not executed as options[0] = NULL and options[1] = 0
My comedi_config command is:
comedi_config -i Ad8.OUT /dev/comedi0 Alphi_Ad8
Any ideas would be welcome
