We have a custom board board based on the BeagleBoneBlack reference design. And we have hard time to bring up the WL18 interface.
Help would be greatly appreciated to have this up and running.
I have seen and read other posts about identical/similar issues and resolutions, but unfortunately none of the winning solutions appear to solve our issue.
ISSUE
MMC3 scan error on init, error -5 (IO error)
HARDWARE
As BBB except:
- WL18 WLAN is connected to MMC3 (balls V12, T13, T12, R12, V13, U13)
- WL_EN is on gpio0_26 (ball T11)
- WL_IRQ is on gpio0_27 (ball U12)
- BT_EN is on gpio0_22 (ball U10)
- As for the BBB, we have a level shifter (3,3V/1,8V). Buffer enable connected to gpio0_11 (ball T5). I initially mapped it in the device tree as an always on LED but it came high too late, i.e, after WL_EN was used. So it is forced high in the MMC init (omap_hsmmc.c) for now. The plan is to use a gpio-hug eventually (did not work at first glance, will see later).
KERNEL
For the kernel, we are using the kernel from the TI SDK 01.00.00.00.
The kernel sources are from the file am335x-evm-sdk-src-01.00.00.00.gz.
Kernel version = 3.14.26-gb9df364-dirty
And ti-compat-wireless-wl18xx appears to be R8.5
PROCEDURE
We follow the instructions for kernel 3.14 integration here: processors.wiki.ti.com/.../WL18xx_AMxxx_Platform_Integration_Guide

The following additions were made to our device tree.

BOOT LOG
My current boot log is attached. Unfortunately, I do not see as much detailed traces as i would like to.
I enabled early printk in my config. Are there other useful config_xxx tag I should enable allowing to see more mmc and wlcore prints?

INTERESTING OBSERVATION
Wanting to "hard jump" the level shifter buffer enable on the 3,3 V to make sure it is was up in time,
I happened to change the boot mode that shares the same signal.
By forcing the signal to 3,3V, I accidently caused the boot mode to go from BOOT_MODE[15:14] from 01b to 11b,
causing the clock spec to go from 24MHz to 26MHz, thus causing the processor to run slower I assume.
When I do so, the mmc3 and wlcore inits appear to go one step further.

I was wondering if mcc clock speed could be the issue here. Especially since our lines are a little longer than on the BBB.
The level shifter is at about 1/2 inch from the WL18 and at about 5 inches from the AM335.
Full boot log for this attempt is attached also.
