Subject: [U-Boot] socfpga: immediate hang when accessing memory at 0x10000
Date: Tue, 26 Aug 2014 13:12:46 +0200 [thread overview]
Message-ID: <20140826111246.GA32102@amd> (raw)
Hi!
I got networking and MMC card to work on recent u-boot, but now I'm
hitting DRAM region where any access just hangs the system.
Any idea what could be there / why is it hanging?
I tried reset_assert_all_bridges(), but no change.
Memory from md 100000 works ok, again, so it seems the only
problematic window is 10000 to 100000.
Best regards,
Pavel
