[U-Boot] BUG: cannot boot with CONFIG_LOG

[Heinrich Schuchardt]

Hello Simon,

I am running vexpress_ca15_tc2_defconfig with qemu:

QEMU_AUDIO_DRV=none qemu-system-arm \
-M vexpress-a15 -cpu cortex-a15 \
-kernel u-boot \
-net user -net nic,model=lan9118 \
-m 1024M --nographic \
-drive if=sd,file=../img.vexpress,media=disk,format=raw

If I enable CONFIG_LOG=y starting U-Boot fails.

This is due to log_init() returning -ENOMEM.
If I change
return -ENOMEM;
to
return 0;
the board boots.

log_init() is called twice:
common/board_r.c:680:   log_init,
common/board_f.c:760:   log_init,

If I remove the call from common/board_f.c the board boots.

What do you expect
debug("%s: Cannot allocate memory\n", __func__);
to do if logging is not yet initialized and the board is out of memory?

Even if I #define DEBUG 1
I get no output created by this line.

Best regards

Heinrich
