The calibrator and other useful utilities for TI wireless solution, based on wl12xx driver. Calibration is a process in which specific radio configuration parameters are generated and saved into the NVS file, later to be used by the wl12xx driver upon initialization. These configuration parameters are specific to the chip on the specific design and therefore are sent back to the driver to store in non-volatile memory for later use. Upon initialization, the wl12xx driver will load an NVS file where it expects to read those parameters and send them to the chip. The NVS file contains 2 main parts - one stores the calibration parameters and the other one stores initialization information required for the wl12xx driver. --- Build procedure Kernel configuration. Make sure your kernel is configured to support nl80211 testmode commands (NL80211_TESTMODE=y). Also enable following configurations: CRC7=m FW_LOADER=m In userspace there is dependent on libnl v2.x package. It can be downloaded from http://www.infradead.org/~tgr/libnl/files/libnl-2.0.tar.gz Set follow environment variables: export NFSROOT=export CROSS_COMPILE=arm-none-linux-gnueabi- make make install --- How to calibrate Automatic calibration procedure. * Make sure all modules up to wl12xx.ko are loaded. wl12xx_sdio.ko should NOT be loaded. * The firmware directory must be writeable. * A "plt firmware" must be present in the firmware directory. calibrator plt autocalibrate dev Device name. Probably wlan0 kernel mod Full path to wl12xx_sdio.ko kernel module ini Full path to Radio param ini file nvs Full path of nvs file. Must be the real path as wl12xx will load it This command will perform the following steps: * Parse the ini and create an nvs without calibration data. * Load kernel module. * Perform TxBip and update nvs with calibration data. * Unload kernel module. Android example: ./calibrator plt autocalibrate wlan0 /system/lib/modules/wl12xx_sdio.ko TQS_D_1.7.ini /etc/firmware/ti-connectivity/wl1271-nvs.bin 00:01:02:03:04:05 Native Linux example: ./calibrator plt autocalibrate wlan0 /lib/modules/wl12xx_sdio.ko TQS_D_1.7.ini /lib/firmware/ti-connectivity/wl1271-nvs.bin 00:01:02:03:04:05 --- How to choose INI file For Beagle board and Panda board use ini_files/127x/TQS_S_2.6.ini For Blaze board with ES2.1 or ES2.1 use ini_files/128x/TQS_D_1.7.ini --- How to change MAC address in calibrated NVS ./calibrator set nvs_mac [ ] If the MAC address missing, the random valid value will be added. --- How to dump NVS file calibrator get dump_nvs [ ] --- Detailed instructions for calibrator procedures Normally you should use the autocalibrate command but it's also possible to run each step manually. TxBip procedure (calibration) It is important to set MAC address to an interface before the procedure. For example, `ifconfig wlan0 hw ether xx:xx:xx:xx:xx:xx' calibrator wlan0 plt power_mode on calibrator wlan0 plt tx_bip <0|1> <0|1> <0|1> <0|1> <0|1> <0|1> <0|1> <0|1> calibrator wlan0 plt power_mode off Result of this procedure is new NVS file created locally ./new-nvs.bin In order to use it, copy the file to /lib/firmware/wl1271-nvs.bin and reload. TxCont procedure calibrator wlan0 plt power_mode on calibrator wlan0 plt tune_channel calibrator wlan0 plt tx_cont calibrator wlan0 plt tx_stop calibrator wlan0 plt power_mode off Description: This test sends packets of data directly to air. It receives several parameters as described bellow, to enable diversity of operational modes. It is mostly used to see Energy and radio impact on Air. Content of Packet can be Random, or Zero, One, Zero, one... Packets send are configurable with following parameters: Delay between packets in microseconds Rate 1 Mbps - 0x00000001 MCS_0 - 0x00002000 2 Mbps - 0x00000002 MCS_1 - 0x00004000 5.5 Mbps - 0x00000004 MCS_2 - 0x00008000 6 Mbps - 0x00000008 MCS_3 - 0x00010000 9 Mbps - 0x00000010 MCS_4 - 0x00020000 11 Mbps - 0x00000020 MCS_5 - 0x00040000 12 Mbps - 0x00000040 MCS_6 - 0x00080000 18 Mbps - 0x00000080 MCS_7 - 0x00100000 24 Mbps - 0x00000200 36 Mbps - 0x00000400 48 Mbps - 0x00000800 54 Mbps - 0x00001000 Size of data field in MPDU (in bytes, 0 - 2284) Amount - number of packets in case of using series mode Power - output power in dBm*1000 Seed - value for the scrambler Packet mode - 0-single, 1-multipile, 3-continuous, 4-FCC DC on/off - activate DCF gi - guard interval on/off for 11n rates Preamble 1 Mbps - long preamble mode=0 2, 5.5, 11 Mbps - long preamble mode=0, short preamble mode=1 6, 9, 12, 18, 24, 36, 48, 54 Mbps - ofdm preamble mode=4 from MCS_0 to MCS_7 - n mixed mode preamble mode=6, greenfield preamble mode=7 Type is 0-data packet, 1-ack, 2-probe req, 3-random data, 4-user data Scrambler - on/off CLPC range 0-100 is disable calibration Sequence number mode (incremented or fixed) Destination Mac address RxStat procedure There are 2 ways to do it - short where all parameters has default values and full where you have to set all parameters manually. Short way: calibrator plt rx_statistics In the short way each time the statistics will be reseted. Full way: calibrator wlan0 plt power_mode on calibrator wlan0 plt start_rx_statcs calibrator wlan0 plt get_rx_statcs calibrator wlan0 plt stop_rx_statcs calibrator wlan0 plt power_mode off While willing to reset the statistic run: calibrator wlan0 plt reset_rx_statcs Update NVS file procedure This is procedure changes ini part of NVS file. It helps when there is need to change ini part of NVS which already calibrated. calibrator set upd_nvs [ [ ]] If NVS filename parameter not provided the current NVS file will be used from destination directory (usually /lib/firmware). --- Miscellaneous procedures Read MAC address from NVS file calibrator get nvs_mac [ ] Set NVS to use auto FEM detection calibrator set autofem 1 Set FEM manufacturer calibrator set fem_manuf 0|1 Tone transmission testing Get in PLT mode calibrator wlan0 plt power_mode on Run TxTone transmission calibrator wlan0 plt tx_tone Tone type 1 - Carrier FeedThrough 2 - Single tone Power [0 - 10000] mdB Stop transmission calibrator wlan0 plt tx_stop Get out from PLT mode calibrator wlan0 plt power_mode off ------------------------------------------------------------------------------- The project can be accessed from git repository: git clone git://github.com/TI-OpenLink/ti-utils.git
