The calibrator and other useful utilities for TI wireless solution, based on the wl12xx and wl18xx drivers. --- 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=<path to roofs of a target where installed libnl library> export CROSS_COMPILE=arm-none-linux-gnueabi- make make install --- How to calibrate wl12xx 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. 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> <kernel mod> <ini> <nvs> <mac> 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 (wl12xx) 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 <nvs file> [<mac addr xx:xx:xx:xx:xx:xx>] If the MAC address missing, the random valid value will be added. --- How to dump NVS file (wl12xx) calibrator get dump_nvs [<nvs filename>] --- Detailed instructions for calibrator procedures (wl12xx) 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.

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 <ini file> [<old nvs file> [<new nvs file>]] 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 [<nvs filename>] 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> <power> 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 ------------------------------------------------------------------------------- --- wl18xx calibration The wl18xx hardware does most of the calibration by itself, so the calibration per-se is not necessary. The tool provides command for PLT (Production Line Tests), though. --- MAC addres for wl18xx For now (as of 20.04.2012), the wl18xx driver uses an NVS file with the same format as the one used for wl12xx. Most of the parameters in this file are not used. One of the parameters that is still used is the MAC address. The wl18xx chip has its own MAC address derived from FuseROM, but this address can be overriden by setting it in the NVS file. If the MAC address in the NVS file is 00:00:00:00:00:00, the default MAC, burnt in FuseROM is used. 1. The following procedure allows the MAC address to be changed in the NVS file: calibrator wlan0 plt set_mac <nvs_file> [<MAC address>|from_fuse|default] <MAC address> specific address to use (XX:XX:XX:XX:XX:XX) from_fuse try to read from the fuse ROM, if not available the command fails default write 00:00:00:00:00:00 to have the driver read from the fuse ROM, fails if not available 00:00:00:00:00:00 force use of a zeroed MAC address (use with caution!) 2. To read the MAC address that is derived from the FuseROM, the following command can be used: calibrator wlan0 plt get_mac --- wl18xx power modes To be able to use the PLT procedures, the firmware needs to be booted in PLT-mode. To do so, the wl18xx modules need to be loaded and the interface wlan0 must be down. Then use the following command to boot it in PLT-mode: calibrator wlan0 plt power_mode on And to turn it off (so that it can be booted in normal mode by putting the wlan0 interface up again): calibrator wlan0 plt power_mode off --- TX simulation in wl18xx The wl18xx firmware supports TX packets simulation. With the following commands, the device will send pre-defined packets to the air: 1. Boot the firmware in PLT mode: calibrator wlan0 plt power_mode on 2. Select the channel to use: calibrator wlan0 wl18xx_plt tune_channel <channel> <band> <bandwidth> Eg., to use channel 1 with no HT bandwidth: calibrator wlan0 wl18xx_plt tune_channel 1 0 0 Eg., to use channel 136 with 40MHz bandwidth: calibrator wlan0 wl18xx_plt tune_channel 136 1 1 Eg., to use channel 1 with 40MHz Minus bandwidth: calibrator wlan0 wl18xx_plt tune_channel 1 0 2 Eg., to use channel 1 with 40MHz Plus bandwidth: calibrator wlan0 wl18xx_plt tune_channel 1 0 3 3. Start transmitting packets: calibrator wlan0 wl18xx_plt start_tx <delay> <rate> <size> <mode> <data_type> <gi> <options1> <options2> <source MAC> <dest MAC> <20|40> Where the following parameters can be used: <delay> delay between packets in us <rate> transmission rate: 0 = 1.0 Mbps 1 = 2.0 Mbps 2 = 5.0 Mbps 3 = 11.0 Mbps 4 = 6.0 Mbps 5 = 9.0 Mbps 6 = 12.0 Mbps 7 = 18.0 Mbps 8 = 24.0 Mbps 9 = 36.0 Mbps 10 = 48.0 Mbps 11 = 54.0 Mbps 12 = 6.5 Mbps (MCS0) 13 = 13.0 Mbps (MCS1) 14 = 19.5 Mbps (MCS2) 15 = 26.0 Mbps (MCS3) 16 = 39.0 Mbps (MCS4) 17 = 52.0 Mbps (MCS5) 18 = 58.5 Mbps (MCS6) 19 = 65.0 Mbps (MCS7) 20 = 65.0 Mbps + 10% (MCS7 SGI) 21 = MCS8/MCS4 at 40MHz 22 = MCS9/MCS5 at 40MHz 23 = MCS10/MCS6 at 40MHz 24 = MCS11/MCS7 at 40MHz 25 = MCS12/MCS7 at 40MHz SGI 26 = MCS13 27 = MCS14 28 = MCS15 29 = MCS15 SGI <size> packet size (bytes) <mode> number of packets (0 = endless) <data_type> TBD <gi> guard interval (0 = normal, 1 = short) <options1> TBD <options2> TBD <source MAC> source MAC address (XX:XX:XX:XX:XX:XX) <dest MAC> destination MAC address (XX:XX:XX:XX:XX:XX) <channel width> channel width (0 = 20 MHz, 1 = 40 MHz) For example, to transmit packets continuously at 500ms intervals with 1024 bytes length (plus headers) at 65 Mbps (MCS7) on a 40MHz channel: calibrator wlan0 wl18xx_plt start_tx 500000 19 1024 0 0 0 0 0 00:11:22:33:44:55 01:02:03:04:05:06 1 note, In start_tx there are 3 fields that are TBD and the user must send the command with some value, please “0”: - <option1> and <option2> set as 0. - <data_type> set as 0. 4. To stop transmitting packets: calibrator wlan0 wl18xx_plt stop_tx NOTE: it is very important to stop transmitting packets before attempting a second start_tx command! If this is not done properly, the results will be undefined (and probably not what you want). --- RX statistics in wl18xx The wl18xx firmware can capture packets from the air and report statistics about it. This can be used to make sure the calibration, antennas and RF in general is working properly. 1. Boot the firmware in PLT mode: calibrator wlan0 plt power_mode on 2. Select the channel to use: calibrator wlan0 wl18xx_plt tune_channel <channel> <band> <bandwidth> Eg., to use channel 1 with 20MHz bandwidth: calibrator wlan0 wl18xx_plt tune_channel 1 0 0 Eg., to use channel 136 with 40MHz bandwidth: calibrator wlan0 wl18xx_plt tune_channel 136 1 1 3. Start gathering data: calibrator wlan0 wl18xx_plt start_rx 4. Read the current statistics about packet reception: calibrator wlan0 wl18xx_plt get_rx_stats 5. Stop gathering RX statistics: calibrator wlan0 wl18xx_plt stop_rx --- TX set power in wl18xx 1. Boot the firmware in PLT mode: calibrator wlan0 plt power_mode on 2. Select the channel to use (see above): calibrator wlan0 wl18xx_plt tune_channel <channel> <band> <bandwidth> 3. set the power calibrator wlan0 wl18xx_plt set_tx_power <output_power> <level> <band> <primary_channel> <2nd_channel> <antenna> <non_serving_channel> <channel_limitation> <frontend_limit> <gain_calculation> <analog_gain_control_id> <post_dpd_gain> Where the following parameters can be used: <output_power> Desired power output supplied in dBmX1000 at 125 resolution (1/8 dB), i.e. 16.125[dBm] = 16125 <level> Indicates which table to refer to (0-3) <band> 0 = G band 1 = A band <primary_channel> Operation channel <2nd_channel> Select the 2nd channel in siso40 0 = below 1 = above <antenna> Used for Tx antenna select. 0 = auto mode 1 = TX1 2 = TX2 3 = Both TX1 & TX2 <non_serving_channel> Will this level be used for non serving channel <channel_limitation> Notifies the PHY FW when to discard internal limits, disable only per channel limits <frontend_limit> Notifies the PHY FW when to discard external limits - disable per rate limits when using external PA platform <gain_calculation> Used to determine one of three gain calculation modes (debug only) 0 = normal operation 1 = debug mode 2 = override mode <analog_gain_control_id> When gainCalcMode is set to mode 3, this indicator will be used to indicate the user's chosen analog index <post_dpd_gain> sets the post DPD gain Good default values are: calibrator wlan0 wl18xx_plt set_tx_power <out_power> 0 <band> <channel> <freq2ndChInd> 0 0 0 0 1 0 0 For example, to set the power to 20dBm @ channel 11 use the following command: calibrator wlan0 wl18xx_plt set_tx_power 20000 0 0 11 0 0 0 0 0 1 0 0 4. start transmit (see start TX) --- Set antenna mosde in wl18xx 1. Boot the firmware in PLT mode: calibrator wlan0 plt power_mode on 2. set the antenna : calibrator wlan0 wl18xx_plt set_antenna_mode <primary_rf_channel> <rf_chain_1_enable> <rf_chain_2_enable> ------------------------------------------------------------------------------- The project can be accessed from git repository: git clone git://github.com/TI-OpenLink/ti-utils.git
