Hello TI,
We have a custom board using a am335x micro that has a wl1831 chip on the mmc2 bus for wifi, (there is an eMMc on mmc1 and sD on mmc0). We are able to connect to mobile hotspots and get ip addresses through the Android desktop system settings UI, so we are past the platform integration phase.
Now we are having trouble calibrating the chip and would like your direction. The calibration wiki (http://processors.wiki.ti.com/index.php/WL18xx_Calibration_Process) instructs users to run the wlconf utility on their device's wl18xx-conf.bin file, but out drivers do not use this firmware file - instead they use wl18xx-fw-mc.bin
Here is some dmesg output from our device for when we run the 'insmod wlcore_sdio.ko' and 'netcfg wlan0 up' command with the BOOT_DEBUG flag set:

Also - our version of wlconf is not able to parse the wl18xx-fw-mc.bin file:
root@android:/system/etc/firmware/ti-connectivity # wlconf -i wl18xx-fw-mc.bin -g
>>incompatible binary file
>>expected 0x10e100ca 0x00050005
>>got 0x0f000000 0x00000000
Our code for the wl18xx drivers and utilities came from the pre-packaged sources of the TI-Android-JB-4.2.2-DevKit-4.1.1 software development kit (which can be found at downloads.ti.com/sitara_android/esd/TI_Android_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_1/exports/TI_Android_JB_4.2.2_DevKit_4.1.1.bin) This is the main code base that we started with (The Linux kernel version is 3.2).
We did not get any version info from the following files:
1) strings wlcore_sdio.ko | grep 'ol_r8\|Build-' -m1
2) strings wlcore.ko | grep 'ol_r8\|Build-' -m1
3) strings wl18xx.ko | grep 'ol_r8\|Build-' -m1
4) strings wl18xx-conf.bin | grep Rev
We did get the following version numbers from 'strings wl18xx-fw-mc.bin | grep Rev'
FRev 8.4.0.0.26
FRev 8.2.0.0.146
My general feeling is that we need to update the versions of either the drivers or the utilities, or both. If so then what versions do we need, where do we get the source code, and what are the build instructions?
Thanks for your support!
-Jake
