IntroductionThis document will introduce the basic concept of whole MP structure, the meaning of items appeared in UI of MP Tool, and how to operate this tool to execute RF verifications.II. MP StructureThere are three elements to compose a basic MP structure● PC (with MP tool UI)● DUT (Realtek WiFi device with daemon ‘UDPServer’ launched) ● Ethernet Cable (for communication between PC & DUT)Run UI: MP Tool Run daemon: UDPServerFigure 1. basic MP structure©2013 Realtek Semiconductor Corp.6The procedure of running MP is like this:1. User control UI of MP tool.2. MP Tool send MP commands (according to UI operation) to DUT in form of UPD packets3. DUT receive & parse these UPD packets by daemon – UDPServer4. UDPServer execute these MP commands in system.5. MP operations can be performed by these MP commands. (like switch channels, select Tx powers, send packets…)(PC Side)(DUT Side)Figure 2. example of MP flow©2013 Realtek Semiconductor Corp.7III.

MP Tool OperationThis chapter will introduce how to operate MP Tool. Before going through these steps, the MP nfjrom has to be loaded to the DUT:Step 0. Loading MP nfjrom to DUTFirst plug in the DUT and press ESC when booting to enter console mode of bootloader. Then use Windows CMD command line to execute tftp to transfer MP nfjrom to the DUT. The default IP address of bootloader is 192.168.1.6, so the command looks like this:tftp –i 192.168.1.6 put “C:\patch\nfjrom”Step 1. Open MP session- select correct <EFUSE TYPE> or input C9&CC value manually for DUT (Only RTL8192D needs this step)- input the correct <IP Address> of DUT- select your <IC TYPE> (just follow default setting like below pictures) - press <Open> buttion.Figure 6.default setting of 8192C for open MP sessionStep 2. Config WLAN settingIf open MP session successfully, it will show the chip name on the UI and all RF items can be selected (or input value) now.Then users can try to config WiFi setting as their wish, but please follow this table for listed items.PhyBand and MAC/PHY Mode will be auto selected after open except the IC TYPE is RTL8192D .©2013 Realtek Semiconductor Corp.302. Select Test Items and Start MP Verification.After WiFi setting done, user can select <Test Item> want to execute, and then press <Start> to start test, press <Stop> to stop test.3. Use Flash Page/Flash_AC Page to save calibration data.From test results, user may now know which specific Tx power index is suitable for specific data rate for some channels, so, user can use Flash page to store these calibration data.4. End MP SessionJust press <Close> button in General Page.V. MP CommandsAs mentioned before, MP operation is formed by executing MP commands, any of user’s actions to UI of MP tool were all converted into sets of MP commands, this chapter will introduce the basic MP commands(format, usage, examples…), then user can try to type these commands by conso le interface, in order to do MP operations without MP Tool program installed in PC.1.IntroductionRealtek WiFi Linux driver supports driver based Mass Production functions. Customers can utilize these functions to do EMI test and other simple TX and RX test. Under Realtek WiFi turnkey, we use Linux utility “iwpriv” to get and set I/O control to WLAN driver. The following commands are executed under Linux command prompt. The MP functions will only operate after the WLAN interface is opened.age1.Start MP mode:packets. All connection with other stations will be broken. Beacon transmitting is also stopped. If the original state is client mode, the roaming will be stopped.2.Stop MP mode:other commands. It will not return to normal operation mode. System should close the WLAN interface and open again to get WLAN work normally.©2013 Realtek Semiconductor Corp.31©2013 Realtek Semiconductor Corp.323. Set Tx rate:value sets the rate of Tx packets.For example, set Tx rate to MCS 7: iwpriv wlan0 mp_rate 135Note.Since 8814 and 8194 support 3 spatial stream, the values for HT rate extends to 151, and the base value for VHT is 160 rather than legacy 144.For 8814 and 8194, the value is as following:E.g. set Tx rate to VHT NSS1 MCS 7: iwpriv wlan0 mp_rate 167©2013 Realtek Semiconductor Corp.334. Set operational channel:Set the operational channel of transmitting and receiving packets.E.g. set channel to 6:iwpriv wlan0 mp_channel 65. Set operational bandwidth:sgi sets guard interval of transmitting MCS packet, 1 for short GI, 0 for long GI Set the operational bandwidth for transmitting and receiving packets. Set the guard interval fortransmitting MCS packets. If the parameters are not given, the default action is set bandwidth to 20M mode and long GI to transmitting packets.For example, set bandwidth to 40M, and no shortGI: iwpriv wlan0 mp_bandwidth 40M=1,shortGI=06. Set Tx power:b sets Tx power level for path Bc sets Tx power level for path Cd sets Tx power level for path DSet the transmitting power level of path A, B, C, and D. If the DUT only has one path, just specify patha.For example, set path A power index to 20, and path B to 30: iwpriv wlan0 mp_txpower patha=20,pathb=307. Set xcap value:Set the PHY related parameters of crystal capacitor.For example, set crystal capacitor to 31: iwpriv wlan0 mp_phypara xcap=31©2013 Realtek Semiconductor Corp.348. Set antenna for Tx:for antenna D, ab for antenna A and B, abc for antenna A, B, and C, and abcd for antenna A, B, C, and DSet the operational antenna for Tx on the target board.For example, set Tx operational antenna to path A: iwpriv wlan0 mp_ant_tx a9.Set antenna for Rx:ant sets the operational antenna for Rx, a for antenna A, b for antenna B, c for antenna C, d for antenna D, ab for antenna A and B, abc for antenna A, B, and C, and abcd for antenna A, B, C, and DSet the operational antenna for Rx on the target board.For example, set Rx operational antenna to path A: iwpriv wlan0 mp_ant_rx a10. Start air Rx mode:start clears counters and start to accumulate Rx packets stop stops counts and show the statisticsThis command is for air receiving test. Use start command to clear all the counters and start toaccumulate the received packets. Use stop command to stop counting and show the statistics of correct packets and CRC-error packets.11. Start continuous Tx mode:n sets the number of packets to send background sends packets in background mode stop stops the background sending pkt sends packet tx, i.e., not sent by hardware cs sends carrier suppression stone sends single toneThis command is for continuous transmitting test. Use time command to assign the time to send packets. Use count command to assign the number of packets to send. If both of time and count are not specified,©2013 Realtek Semiconductor Corp.35the sending function will continue infinitely. It can be stopped when any key is pressed (should be specifically implemented in other platform) while background command is not specified. If cs isspecified, the sending signal will be a carrier suppression signal. Use stone command to send single tone signal for frequency testing. If stone is specified, the sending signal will be single tone and not adistinguishable packet any more. Use background command to tell driver to send packets in background. The command line control will return and packet sending is continuous. It can be stopped by stopcommand. By default, packets will be sent by hardware for shorter duty cycle. If pkt is specified, packets will be sent by software.For example, start background packets Tx infinitely: iwpriv wlan0 mp_ctx background,pkt12.Query air tx/rx statistics: This command is for packet counting. Under packet transmitting, use this command to get the number of packets being transmitted. Under receiving, use this command to get the statistics of correct packets and CRC-error packets.13. Set Band ModeSet the operational band mode on the target board. This is set only for RTL8192D.14. Start air Rx mode: off stops mp dig.This command is only for RTL8812AR/BR and RTL8814 while receiving test. Use on command to start mp dig and it will change the initial gain setting depends on false alarm counter. Use off command to stop mp dig and it will set initial gain to default.15. Start power tracking:stop stop power trackingStart power tracking and set the tracked thermal as xFor example, start power tracking and set the tracked thermal as 32: iwpriv wlan0 mp_pwrtrk ther=32©2013 Realtek Semiconductor Corp.3616. Start hardware Tx (8197F, 8812BR, 8814 and 8194 only):Start to transmit hardware TX packets. The packet type is described in the argument set, including Tx rate, packet period, MAC address, .etc.The argument set contains 56 arguments, which are listed in order as below:{Ntx:4, Mode:3, bEnPMacTx:1}, TX_RATE, TX_RATE_HEX, TX_SC, {BandWidth:3, NDP_sound:1, bLDPC:1, bSTBC:1, bSPreamble:1, bSGI:1}, m_STBC, PacketPeriod, PacketCount, PacketLength, PacketPattern, SFD, SignalField, ServiceField, LENGTH, CRC16[0], CRC16[1], LSIG[0], LSIG[1], LSIG[2], HT_SIG[0],HT_SIG[1],HT_SIG[2],HT_SIG[3],HT_SIG[4],HT_SIG[5], VHT_SIG_A[0], VHT_SIG_A[1],VHT_SIG_A[2],VHT_SIG_A[3],VHT_SIG_A[4],VHT_SIG_A[5], VHT_SIG_B[0],VHT_SIG_B[1],VHT_SIG_B[2],VHT_SIG_B[3], VHT_SIG_B_CRC,VHT_Delimiter[0], VHT_Delimiter[1], VHT_Delimiter[2], VHT_Delimiter[3], MacAddress[0], MacAddress[1], MacAddress[2], MacAddress[3], MacAddress[4], MacAddress[5]Since the calculation of arguments LSIG , HT_SIG , VHT_SIG_A, .etc involves floating point operation, these arguments are calculated by MP tool. Please refer to MP tool and MP API to generate the arguments and issue this command.For example, start to transmit 40M, channel 38, MCS7 packets infinitely: iwpriv wlan0 mp_pmac_ctx17,-121,19,0,32,1,0,100,0,0,0,0,0,0,3,-24,0,0,0,0,0,0,0,0,0,0,-53,6,2,-121,-24,3,7,84,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-1,-1,-1,-1,-1,-13. ExamplesThe standard procedure is, firstconfig WiFi mibs to determine types of Band(5G/2.4G), Mode(A/B/G/N) and PA(extPA/intPA) then open WiFi driver and enter MP mode. then use mp commands to dynamically set channel, rate, antenna, power level… then use mp commands to perform Tx/Rx verifications and query statistics. after done testing exit MP mode and re-open WiFi driver.The following introduces the command lists for some examples.1.
