Subject: [Qemu-devel] [PATCH] mips: Fix incorrect jump instruction in YAMON mini-bootloader print function.
Date: Tue, 6 Sep 2011 16:41:56 -0400 [thread overview]
Message-ID: <4E668594.4060207@adrake.org> (raw)
The print function is listed in the vector table as 0xbfc00808. The backedge
of the loop is improperly encoded, and so jumps to 0xb0000814 instead of the
desired 0xbfc00814.
