Wl18xx-fw-4.bin

Yesyou can get the firmware revision by using the command line utilities "string" and "grep", e.g. "strings /lib/firmware/ti-connectivity/wl18xx-fw-4.bin grep Rev". This information can also be found here:

I am working on WL1831 MODULE which is interfaced with TI DM368 via SDIO 0 . The module is getting detected while the board gets booted. I have a kernel 2.6.37 running on DM368. I have connected all sdio lines ( sdio_data lines, sdio_cmd, sdio_clk), wlan_enable and wlan_irq gpio pins between the host and the wireless module via the level shifter TXS0108EPW. I am using the driver version R8.5 backported for this kernel. I have already tested the driver on a reference board similar to the target board I am using now. It was working fine and I was getting the wireless interface up as well.

Now I am using the same driver on my target board specified above. I am inserting the modules as external modules. When I do " insmod wlcore_sdio.ko " I get the prints related to the loading of the driver after a long time..may be 4-5 minutes. I get the logs as follows , which I hope indicates correct loading of the driver.

I have the firmware file inside the folder lib/firmware/ti-connectivity wl18xx-fw-4.bin. Permissions are also correct. I have also probed the enable signal. I appears to be correct. Still it shows its not able to get the firmware. What can be the reason for this? Is it due to the very slow response happening while doing insmod wlcore_sdio.ko and ifconfig wlan0 up ?

That said, your 170 MHz SYSCLK8 is way out of spec. I don't think that has anything to do with the "could not get firmware" error, but once you get passed that issue I expect this will come up soon enough.
