For some reason, when I run ifconfig -a after my Beagleplay boots, eth0 is down and I can not use “ifup eth0”, I get “ifup: ignoring unknown interface eth0”. Also, I noticed the wireless interface wlan0 is not even listed in ifconfig -a output. When I run iw, it’s unknown device. What am I missing?
Please share your full serial boot log, i’d like to see what version of u-boot.
Regards,
Looks like uboot doesn’t find it either. I’m using “edvo3_uboot_a53_defconfig” for uboot
CORTEXA build and “edvo3_uboot_r5_defconfig” for CORTEXR uboot build. UBOOT VERSION 2023.04
okay not sure on that config… but 2023.04-00759 smells like TI’s u-boot fork, so wifi should work…
Regards,
I know TI had a problem with different versions of their SK-AM62 dev boards, because I have both versions of the board. One has WIFI onboard, the other doesn’t. That turned out to be a device-tree change, but I checked the Beagleplay device tree to make sure the same change was there and it was. So very weird. I’ll keep digging and let you know what I find.
I got eth0 up & running by switching from TI u-boot to beagleboard u-boot, branch v2024.04-rc3-BeaglePlay. It was successfully built using am62x_evm_a53_defconfig and am62x_evm_r5_defconfig. Once beagleplay booted via microSD, the eth0 interface was up & running. Not quite sure what went wrong with the u-boot from TI I was using.
just note the biggest thing missing on that branch is u-boot “ethernet” support… RFC patches have been posted to u-boot, once i verify they work, i’ll add them to that branch or rc4, depending on what comes first…
Regards,
I did notice the u-boot ethernet had a problem, but the eth0 interface came up during kernel init and it wasn’t doing that before. Now I’m chasing the wlan0 problem. Getting a failure trying to load “regulatory.db”. I have no idea where this file comes from or how to fix this error. Do you?
dmesg output I’m seeing:
