downloading firmware
Hi,
I wanted to download firmware via the hotplug mechanism...I just wrote a simple module for the sake of testing. This is the module: static struct device dev = { .bus_id = "dev" }; static void sample_probe_default(void) { const struct firmware *fw_entry =NULL; int k; printk("firmware_driver: device is inserted\n"); k = request_firmware(&fw_entry,"fw_load",&dev); if(k!=0) { printk(KERN_ERR "firmware_driver: Firmware not available\n"); return; } } static int sample_init(void) { device_initialize(&dev); printk(KERN_DEBUG "initialized device\n"); sample_probe_default(); return 0; } static void __exit sample_exit(void) { } module_init (sample_init); module_exit (sample_exit); MODULE_LICENSE("GPL"); When I insert the module, the system hangs...and I get to see the following messages on the screen. firmware_driver: device is inserted fw_register_class_device: class_device_register failed firmware_driver: Firmware not available Also..sme imp things... cat /proc/sys/kernel/hotplug shows /sbin/hotplug I have placed the firmware file i.e. fw_load in the apporpriate directory i.e. /usr/lib/hotplug/firmware/fw_load The firmware.agent is also at the appopriate place /etc/hotplug/firmware.agent The module creates a directory dev but it doesnot contain the required files i.e. loading & data If smeone cud help me out wid dis.... am using kernel version 2.6.6...any help wud be appreciated..Plz also point out anythin dat Iam missing here. |
