[U-Boot] STM32F7 Discovery hangs on master
Hello,
I just tested v2016.11-rc1 on STM32F7 Discovery and it hangs: (gdb) c Continuing. ^C Program received signal SIGTRAP, Trace/breakpoint trap. 0x08000d56 in dram_init () at board/st/stm32f746-disco/stm32f746-disco.c:211 211 FMC_BUSY_WAIT(); (gdb) bt #0 0x08000d56 in dram_init () at board/st/stm32f746-disco/stm32f746-disco.c:211 #1 0x0800d75a in initcall_run_list (init_sequence=init_sequence@entry=0x801b434 <init_sequence_f>) at lib/initcall.c:31 #2 0x0800614e in board_init_f (boot_flags=<optimized out>) at common/board_f.c:1081 #3 0x0800046a in _main () at arch/arm/lib/crt0.S:93 #4 0x0800046a in _main () at arch/arm/lib/crt0.S:93 Backtrace stopped: previous frame inner to this frame (corrupt stack?)
It prints this: U-Boot 2016.11-rc1 (Oct 04 2016 - 19:53:31 +0300)
DRAM: 8 MiB
or this: U-Boot 2016.11-rc1 (Oct 04 2016 - 19:53:31 +0300)
DRAM:
Reverting 25c1b1353ce4b8188de6058f9f3b0d5d2dad8230 (not desirable) makes it working again but I can't seem to write anything to the console.
Offtopic: How are you developing for this board? I'm using gcc 5_4-2016q3 from [0], st-util [1] which exports a /dev/ttyACM0 UART port I'm using at 115200n8 and gdb connected to st-util gdbserver.

I just checked the current master as well as v2016.11-rc1, no issue with anyone. Heres the log: U-Boot 2016.11-rc1 (Oct 07 2016 - 15:52:28 -0700)

uart config is 115200 8N1 (no parity, one stop bit), toolchain: GNU ARM Embedded Toolchain can be used. If I remember it well, the link is https://launchpad.net/gcc-arm-embedded.
