Subject: [U-Boot-Users] Spartan FPGA patch
Date: Tue, 30 Oct 2007 17:51:21 +0200 [thread overview]
Message-ID: <472752F9.9000307@inaccessnetworks.com> (raw)
The following patch fixes a bug in the slave serial programming mode for
the xilinx spartan2 FPGA. A "char val" is declared, but it is used as a
signed char. The check for negative value (<0) is always true on arm, or
any other platform in which the char is not signed by default. As a
result the FPGA cannot be programmed.
By the way, I have tested this code and it works fine, apart from this
error. I am using it in ARM platforms in both slave parallel and slave
serial modes. I am this because I don't see any other platforms using it.
This is a patch against 1.2.0, but I saw that the same code exists in
1.3.0-rc3 as well.
