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 ..." ...
or ...
diff --git a/common/cmd_boot.c b/common/cmd_boot.c index 8f2e070..01825e6 100644 --- a/common/cmd_boot.c +++ b/common/cmd_boot.c @@ -19,6 +19,7 @@ __attribute__((weak)) unsigned long do_go_exec(ulong (*entry)(int, char * const []), int argc, char * const argv[]) { + cleanup_before_linux(); return entry (argc, argv); }
maybe this helps? I just stepped into same problem on an am335x, but had not yet time to look deeper in it ...
