Hi All,

I am very new to the linux device drivers and have a question that linux guru's can answer for me.

I have a host module that is trying to call request_firmware() function and download the firmware to a PCIe card. I have the firmware present in the "/lib/firmware" directory but its not working.

The firmware is provided by the PCIe card vendor which I copied in the "/lib/firmware" directory

I have tried setting the kernel config options but nothing seems to work. This is on LINUX 3.4.11.19 and below are the current config options.

#
# Generic Driver Options
#
CONFIG_STANDALONE=y
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FW_LOADER=y
# CONFIG_DEBUG_DRIVER is not set
# CONFIG_DEBUG_DEVRES is not set
# CONFIG_SYS_HYPERVISOR is not set
# CONFIG_FIRMWARE_IN_KERNEL is not set
CONFIG_EXTRA_FIRMWARE=""

Any help will be much appreciated.

I have been involved with software for many years and have yet to see any program generate the error "not working" yet users persist in claiming that it is the result they get. Programmers work very hard to generate informative error messages and print them on the console and into the system log files. Ignoring them is like closing your eyes and claiming you can't see the play. If you don't know how to find the log files or check the returned error codes, please ask.

A lot more info is needed. What is the PCIe card? Is it graphics, sound, network, or what? Brand and model would be most useful. Exactly what did you copy into the /lib/firmware folder? As smallpond noted, it would be beneficial to post exact errors or logfiles concerning this. How does the system see the card? Open a terminal as root (not sudo) and type lspci and post the output that concerns the card in question.
