Other Parts Discussed in Thread: WL1837
Tool/software: Linux
Team,
Customer is trying to evaluate the WL1837MOD via the element 14 BBONE-GATEWAY-CAPE on the BBB.
To get started they used the latest Debian image (Debian 8.7 2017-03-19 4GB SD LXQT) which seems to work ok without the cape.
After changing the /boot/uEnv.txt (as described in the readme of the cape) the Kernel does not boot anymore:
3. Edit /boot/uEnv.txt
$> sudo nano /boot/uEnv.txt
# Enable the overlay dtb (eMMC/hdmi/etc are disabled) dtb=am335x-boneblack-overlay.dtb
# Enable the gateway/connectivity cape overlay: cape_enable=bone_capemgr.enable_partno=BB-BONE-WL1837
Write out & save edits.
Can you confirm what U-boot/kernel setup for the Device tree should be used with this WL183x CAPE for this kernel release?
Here is the boot log in the different scenario:
-Without the CAPE and with unchanged boot/uEnv.txt Linux can start succesfully:
