From b96088b692a5c44974919ee36e253b6ea8c51972 Mon Sep 17 00:00:00 2001 From: Nick Foster Date: Tue, 31 Aug 2010 16:44:30 -0700 Subject: EEPROM burning in UHD. Changed some USB device handle stuff. Added usrp_init_eeprom.cpp. Hacked up the firmware makefile to behave and to generate .bin EEPROM images instead of IHX. --- host/lib/usrp/usrp1/usrp1_iface.cpp | 21 ++++++++++----------- 1 file changed, 10 insertions(+), 11 deletions(-) (limited to 'host/lib/usrp/usrp1/usrp1_iface.cpp') diff --git a/host/lib/usrp/usrp1/usrp1_iface.cpp b/host/lib/usrp/usrp1/usrp1_iface.cpp index 8756a21c9..4bc18dd16 100644 --- a/host/lib/usrp/usrp1/usrp1_iface.cpp +++ b/host/lib/usrp/usrp1/usrp1_iface.cpp @@ -109,18 +109,19 @@ public: ******************************************************************/ static const size_t max_i2c_data_bytes = 64; + //TODO: make this handle EEPROM page sizes. right now you can't write over a 16-byte boundary. + //to accomplish this you'll have to have addr offset as a separate parameter. + void write_i2c(boost::uint8_t addr, const byte_vector_t &bytes) { UHD_ASSERT_THROW(bytes.size() < max_i2c_data_bytes); unsigned char buff[max_i2c_data_bytes]; - std::copy(bytes.begin(), bytes.end(), buff); + std::copy(bytes.begin(), bytes.end(), buff); - int ret = _ctrl_transport->usrp_control_write(VRQ_I2C_WRITE, - addr & 0xff, - 0, - buff, - bytes.size()); + int ret = _ctrl_transport->usrp_i2c_write(addr & 0xff, + buff, + bytes.size()); // TODO throw and catch i2c failures during eeprom read if (iface_debug && (ret < 0)) @@ -132,11 +133,9 @@ public: UHD_ASSERT_THROW(num_bytes < max_i2c_data_bytes); unsigned char buff[max_i2c_data_bytes]; - int ret = _ctrl_transport->usrp_control_read(VRQ_I2C_READ, - addr & 0xff, - 0, - buff, - num_bytes); + int ret = _ctrl_transport->usrp_i2c_read(addr & 0xff, + buff, + num_bytes); // TODO throw and catch i2c failures during eeprom read if (iface_debug && ((ret < 0) || (unsigned)ret < (num_bytes))) { -- cgit v1.2.3
