Hello Amitkumar, Prameela, I was lucky enough to get hold of RS9113 Evaluation Kit and now I'm trying to get it working with my board via USB and SDIO interfaces but seeing issues here and there: 1) In case of SDIO I see this on interface up with vanilla 4.11.1 kernel: ----------------------->8-------------------- # ifconfig wlan0 up rsi_91x: Sending RX filter frame rsi_91x: rsi_core_qos_processor: Queue number = 4 rsi_91x: rsi_sdio_host_intf_write_pkt: Successfully written onto card rsi_91x: rsi_set_vap_capabilities: Sending VAP capabilities frame rsi_91x: rsi_mac80211_conf_tx: Conf queue 0, aifs: 2, cwmin: 15 cwmax: 1023, txop: 0 rsi_91x: rsi_mac80211_conf_tx: Conf queue 1, aifs: 2, cwmin: 15 cwmax: 1023, txop: 0 rsi_91x: rsi_mac80211_conf_tx: Conf queue 2, aifs: 2, cwmin: 15 cwmax: 1023, txop: 0 # rsi_91x: rsi_mac80211_conf_tx: Conf queue 3, aifs: 2, cwmin: 15 cwmax: 1023, txop: 0 rsi_91x: rsi_channel_change: Set channel: 2412 MHz type: 416 channel_no 1 rsi_91x: rsi_set_channel: Sending scan req frame rsi_91x: rsi_mac80211_config: Configuring Power rsi_91x: rsi_config_power: Set tx power: 20 dBM rsi_91x: rsi_send_radio_params_update: Sending Radio Params update frame rsi_91x: rsi_core_qos_processor: Queue number = 4 rsi_91x: rsi_interrupt_handler: Intr_status = 8 8 4 rsi_91x: Pkt pending interrupt rsi_91x: rsi_mgmt_pkt_recv: Msg Len: 0, Msg Type: 1 rsi_91x: rsi_handle_ta_confirm_type: Invalid TA confirm pkt received rsi_91x: rsi_sdio_host_intf_write_pkt: Successfully written onto card rsi_91x: rsi_core_qos_processor: Queue number = 4 rsi_91x: rsi_sdio_host_intf_write_pkt: Successfully written onto card rsi_91x: rsi_core_qos_processor: Queue number = 4 rsi_91x: rsi_interrupt_handler: Intr_status = 8 8 4 rsi_91x: Pkt pending interrupt rsi_91x: rsi_mgmt_pkt_recv: Msg Len: 0, Msg Type: 1 rsi_91x: rsi_handle_ta_confirm_type: Invalid TA confirm pkt received rsi_91x: rsi_interrupt_handler: Intr_status = 8 8 4 rsi_91x: Pkt pending interrupt rsi_91x: rsi_mgmt_pkt_recv: Msg Len: 321, Msg Type: 2 rsi_91x: rsi_sdio_host_intf_write_pkt: Successfully written onto card rsi_91x: rsi_core_qos_processor: Queue number = 255 rsi_91x: rsi_core_qos_processor: No More Pkt rsi_91x: rsi_interrupt_handler: Intr_status = c 8 4 rsi_91x: Pkt pending interrupt rsi_91x: rsi_mgmt_pkt_recv: Msg Len: 299, Msg Type: 2 rsi_91x: rsi_interrupt_handler: ==> FIRMWARE Assert <== rsi_91x: rsi_interrupt_handler: Firmware Status is 0x65 rsi_91x: rsi_core_qos_processor: Queue number = 255 rsi_91x: rsi_core_qos_processor: No More Pkt ----------------------->8-------------------- and you recent patch series for nwe firmware loading I see something a bit different: ----------------------->8-------------------- mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 25000000Hz, actual 25000000HZ div = 1) mmc0: new SDIO card at address fffd rsi_91x: rsi_probe: Init function called rsi_91x: rsi_init_sdio_interface: Enabled the interface mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot req 50000000Hz, actual 50000000HZ div = 0) rsi_91x: rsi_setblocklength: Setting the block length rsi_91x: rsi_setblocklength: Operational blk length is 256 rsi_91x: rsi_init_sdio_interface: Setup card succesfully rsi_91x: rsi_init_sdio_slave_regs: Initialzing SDIO read start level rsi_91x: rsi_init_sdio_slave_regs: Initialzing FIFO ctrl registers rsi_91x: rsi_sdio_master_access_msword: MASTER_ACCESS_MSBYTE:0x5 rsi_91x: rsi_sdio_master_access_msword:MASTER_ACCESS_LSBYTE:0x41 rsi_91x: rsi_sdio_read_register_multiple: Synch Cmd53 read failed rsi_91x: rsi_sdio_master_reg_read: AHB register read failed rsi_91x: rsi_load_firmware: REGOUT read failed rsi_91x: rsi_hal_device_init: Failed to load TA instructions rsi_91x: rsi_probe: Failed in device init rsi_91x: rsi_91x_deinit: Performing deinit os ops rsi_91x: rsi_core_qos_processor: Queue number = 255 rsi_91x: rsi_core_qos_processor: No More Pkt rsi_91x: rsi_probe: Failed in probe...Exiting RSI-SDIO WLAN: probe of mmc0:fffd:1 failed with error 1 ----------------------->8-------------------- 2) In case of USB I just see: ----------------------->8-------------------- usb 1-1: new high-speed USB device number 6 using ehci-platform usb 1-1: config 1 interface 0 altsetting 0 endpoint 0x83 has an invalid bInterval 255, changing to 11 usb 1-1: New USB device found, idVendor=1618, idProduct=9113 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1: Product: Wireless USB-CDC Network Module usb 1-1: Manufacturer: Redpine Signals, Inc. cdc_acm 1-1:1.0: ttyACM0: USB ACM device ----------------------->8-------------------- I noticed that there're quite some patches floating on linux-wireless mailing list which were not yet merged in upstream kernel (even in linux-next or wireless-testing). So at this point I'm not really sure what could be a safe baseline for my experiments: - if existing vanilla say 4.11 kernel is good enough and things that doesn't work are caused by other problems not related to Redpine module (that would be strange because both USB abd SD-card slot are proven to work pretty well with other devices) - if I need an arbitrary set of patches to get things up and running etc That said if there's a public git repo which contains everything required for Redpine module to work [preferably based on the latest kernel sources] I'd like to get a reference to it. Any hints here are much appreciated. Regards, Alexey
