From 039eceb4b208b2ca5a3465d2f16c8d5a7c7276c7 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Fri, 23 Apr 2010 19:21:47 -0700 Subject: Moved reading the eeprom (dboard ids) onto the host. Created a eeprom parser for the format in the dboard. Removed the support from the microblaze code. --- host/lib/usrp/dboard_eeprom.cpp | 78 ++++++++++++++++++++++++++++++++++++ host/lib/usrp/usrp2/dboard_iface.cpp | 36 +---------------- host/lib/usrp/usrp2/dboard_impl.cpp | 15 +++---- host/lib/usrp/usrp2/fw_common.h | 17 +------- host/lib/usrp/usrp2/usrp2_iface.cpp | 61 ++++++++++++++++++++++++++++ host/lib/usrp/usrp2/usrp2_iface.hpp | 55 +++++++++++++++++++++++++ 6 files changed, 202 insertions(+), 60 deletions(-) create mode 100644 host/lib/usrp/dboard_eeprom.cpp (limited to 'host/lib/usrp') diff --git a/host/lib/usrp/dboard_eeprom.cpp b/host/lib/usrp/dboard_eeprom.cpp new file mode 100644 index 000000000..a8fac602a --- /dev/null +++ b/host/lib/usrp/dboard_eeprom.cpp @@ -0,0 +1,78 @@ +// +// Copyright 2010 Ettus Research LLC +// +// This program is free software: you can redistribute it and/or modify +// it under the terms of the GNU General Public License as published by +// the Free Software Foundation, either version 3 of the License, or +// (at your option) any later version. +// +// This program is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
