[U-Boot] [BUG] bootloop with 2019-07 on Bananapi-r2

[Frank Wunderlich]

Hi again,

whats the correct way to enable debug?

i tried this (add #define DEBUG in common.h):
https://stackoverflow.com/questions/31185603/enabling-debug-mode-for-denx-u-boot-2015-04-on-pandaboard-es

=> uboot does not load (version-line does get printed)

then i've found this:

https://lists.denx.de/pipermail/u-boot/2003-August/002196.html

but DBGFLAGS does not exist in config.mk, i found also no dbg,debug or similar in Makefile and config.mk

i found some debug-options in menuconfig, but don't know which is the right one for this...

maybe DEBUG_LL [=n] ?

regards Frank
