Hi!
In u-boot 2015.04-rc, as soon as execution hits printf("%d"), it
hangs. (Usually, that's after "DRAM: " message).
Now, I have to admit I'm chainloading u-boot from
U-Boot 2013.01.01 (Mar 25 2015 - 15:57:21)
tftp 0x01000040 .../u-boot.bin
Waiting for PHY auto negotiation to complete.. done
ENET Speed is 100 Mbps - FULL duplex connection
Using mii0 device
TFTP from server 10.0.0.6; our IP address is 10.0.0.99
...
Bytes transferred = 325004 (4f58c hex)
# go 0x01000040
...but that worked well for 2014.10, (and is nearly mandatory in my
config).
I'm using cross-compiler from eldk-5.6, but eldk-5.4 crosscompiler
produces same behaviour, and both seem to work for 2014.10.
Any ideas?
Do you have caches on?
Try to disable "dcache off" before "go ..." ...
I tried, and did not get any change. I also tried to flash 2015.04-rc4
directly into NOR to be loaded from SPL (not chainloaded), and it
fails the same way.
Ok.
maybe this helps? I just stepped into same problem on an am335x,
but had not yet time to look deeper in it ...
I did not try the cleanup_before_linux(), but "dcache off" should have
same effect, right?
Hmm.. not exactly... cleanup_before_linux() does also disable the mmu.
bye,
Heiko
