ASPEED AST2050

The AST2050 chipset is an Integrated Remote Management Processor introduced by ASPEED Technology Inc. It is a high performance and highly integrated SOC device designed to support various management functions required for server platforms which require baseboard management, virtual storage functions, and/or KVM-over-IP functions.

Open source support for the AST2050's VGA output (text-mode only) was implemented in coreboot by Raptor Engineering. Full VGA output support requires ASPEED's closed source VGABIOS to be included in the coreboot rom. A rudimentary port of OpenBMC was also developed by Raptor Engineering.

Create the missing /etc/perl/find.pl file

warn "Legacy library @{[(caller(0))[6]]} will be removed from the Perl core distribution in the next major release. Please install it from the CPAN distribution Perl4::CoreLibs. It is being used at @{[(caller)[1]]}, line @{[(caller)[2]]}.\n";

# This library is deprecated and unmaintained. It is included for
# compatibility with Perl 4 scripts which may use it, but it will be
# removed in a future version of Perl. Please use the File::Find module
# instead.

# Usage:
#	require "find.pl";
#
#	&find('/foo','/bar');
#
#	sub wanted { ... }
#		where wanted does whatever you want.  $dir contains the
#		current directory name, and $_ the current filename within
#		that directory.  $name contains "$dir/$_".  You are cd'ed
#		to $dir when the function is called.  The function may
#		set $prune to prune the tree.
#
# For example,
#
#   find / -name .nfs\* -mtime +7 -exec rm -f {} \; -o -fstype nfs -prune
#
# corresponds to this
#
#	sub wanted {
#	    /^\.nfs.*$/ &&
#	    (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
#	    int(-M _) > 7 &&
#	    unlink($_)
#	    ||
#	    ($nlink || (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_))) &&
#	    $dev < 0 &&
#	    ($prune = 1);
#	}
#
# Set the variable $dont_use_nlink if you're using AFS, since AFS cheats.

Configuring and Compiling

### Fetch Sources
git clone -b fido https://git.15h.org/mrothfuss/ast2050-yocto-poky.git ast2050-yocto-poky

cd ast2050-yocto-poky
git clone -b fido https://git.15h.org/mrothfuss/ast2050-yocto-openembedded.git meta-openembedded
git clone https://git.15h.org/mrothfuss/ast2050-yocto-openbmc.git meta-openbmc

### Setup Build
export TEMPLATECONF=meta-openbmc/meta-raptor/meta-asus/conf
source oe-init-build-env
cp -Rp ../local-aspeed.conf conf/local.conf
touch conf/sanity.conf

### Set root password
# The default root password for SSH is 0penBmc.
# Generate a new encrypted password string:
printf "%q\n" $(openssl passwd -1)
# Edit the config file (EXTRA_USERS_PARAMS), replace the password hash with the one you generated.
vim conf/local.conf

### Build. Your ROM will be at tmp/deploy/images/asus/flash-asus-DATETIME
bitbake asus-image

Access your BMC

Scan your network for a new device listening on port 22, then login with ssh

nmap -p 22 10.0.0.1/24
ssh root@IPADDR

You can set the ethernet MAC address to match the one printed on the BMC module.

fw_setenv ethaddr 01:23:45:67:89:ab
reboot

You can access COM2 with screen:

screen /dev/ttyS0 115200

You can use the asus_power.sh command to view/change power states.

asus_power.sh status
asus_power.sh on
asus_power.sh reset
asus_power.sh off
