Hello, thanks for the help so far. I’ve read plenty of info on this forum, the TI forum, and the TI wiki. I think I have the code in my arch/arm/mach-omap2/board-am335xevm.c file correctly updated. I think I’m setting the SDIO pin mux correctly, as well as WLAN_EN, WLAN_IRQ, BT_EN, etc.
However, I just can’t get my beaglebone working with the TiWi-R2 chip. I’ve posted here some of the syslog output (which includes the kernel messages) hoping that someone can help me debug this.
I edited this syslog output to remove unrelated stuff.

Notes:
udevd is killing something related to SDIO
The wl1271 driver is trying several times to communicate with the TiWi chip but fails with error -84
ifconfig -a shows wlan0 has address DE:AD:BE:EF:00:00
Any help would be appreciated. I’ve been trying to get my beaglebone working with the TiWi-R2 chip for weeks.
Thanks for your help,
Tim M
