Hi guys,

what's the trick to get BBB to boot recent kernels nowadays? :-p

I'm using omap2plus_defconfig without CPSW (doesn't link otherwise) with
GCC 10.1.0 (I'll try an older version shortly). Cmdline is the usual
root=/dev/mmcblk0p1 rootwait console=ttyS0,115200n8 (also tried ttyO0)

I get nothing on serial console. Has anyone tried a recent kernel on
BBB?

Cheers

same result with 9.2. Nothing from low level debug either.

I have been using the latest uBoot, DTBs and kernel with no issue 
(except CPSW).

I have booted the BBB and a BBG.  9.2 gcc compiler

This is a build dependency issue.

Maybe check you have a current dtb file? The older dtb files may not
have all the needed data.

Also you probably want to add "earlycon" to your your kernel cmdline
and then you have early output from CONFIG_SERIAL_EARLYCON=y as long
as there's a chosen entry for the device uart. So no need to enable
DEBUG_LL in most cases.

There's "[PATCH net v4] net: ethernet: ti: Remove TI_CPTS_MOD workaround"
being discussed too for the cpsw regression.

Regards,

Tony

I'll give it a shot. Maybe it's something silly I did along the way ;-)

It's been a few years since I touched ARM :-)

yeah, loading all the data from sd card. I am, however, using the u-boot
that came with the board.

cool, I'll try earlycon, then.
