kernel 4.4 can't boot on beaglebone ai #42
Comments
Hi @lichaowuwei , this is correct, the old 4.4 kernel doesn't have the device tree changes required for the beaglebone ai.. at the time of the BBAI release, i was only supporting v4.14.x+ kernels Sorry, but feel free to back port the device tree. Regards, |
how to modify the device tree?any instruction? |
@RobertCNelson hi, why kernel 4.14 can't send and recieve ethercat frame? 4.4 kernel is ok! i printk some message, it seems like that when using 4.14kernel, no frame recieved, and cpsw_rx_handler never be executed! and dmesg say device eth0 entered promiscuous mode. when it not connect with ethercat device, dmesg indicates nomarlly. any thind wrong with the 4.14 kernel? can't use it with ethercat? |
hi @lichaowuwei sorry, i haven't used ethercat, are we missing a config, or ? Regards, |
@RobertCNelson i don't know, it seems like many guys happen to this situation when use beaglebone with ethercat. or any where could try to config ? when downgrade to 4.4 or 3.8, things would be ok. but beaglebone ai could only use 4.14now, i can't boot it with 4.4 or don't know how to config the device tree. |
