Any hint on what's wrong here? Note firmware was successfully loaded on probe a bit earlier. And here I used a firmware blob from linux-firmware git repo, https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rsi_91x.fw > > 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 > > Looks like sdio_readsb() failed for some reason on your platform. > We expect firmware loading to be successful with recent patch series. Hm, that's interesting why stuff used to work before that patch series. At least as you might see from above I got much further with vanilla 4.11 kernel. BTW where may I find new firmware blob which is mentioned in on of the patches ("rs9113_wlan_qspi.rps")? > > 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. > > We don't have a public git repo maintained.

But please add me in Cc list in your upcoming patches as I'm very interested in getting Redpine module working on our new board and will be happy to review them as well as test on my platform. BTW I'm wondering what platform you use for development as a host? I'm wondering if the reason for my failure mentioned above might be in different host CPU architecture or SD-card controller vendor or settings. -Alexey
