OK, let me start with a set of basic questions. What device do you have (brand + model or picture on ebay please;))? What's the device ID? What platform are you working on? Is this error persistent or a one-time thing? Does the vendor driver work with your device? Can you also show content of /sys/kernel/debug/ieee80211/phy*/mt76/eeprom_param ? > [ 3.174960] mt7601u 3-5:1.0: ASIC revision: 76010001 MAC revision: > 76010500 > [ 3.181705] mt7601u 3-5:1.0: Firmware Version: 0.1.00 Build: 7640 > Build time: 201302052146____ > [ 3.573018] mt7601u 3-5:1.0: Warning: unsupported EEPROM version 0d > [ 3.574853] mt7601u 3-5:1.0: EEPROM ver:0d fae:00 > [ 3.816647] usbcore: registered new interface driver mt7601u > [ 10.461251] mt7601u_add_interface idx:0 > [ 10.463193] mt7601u_bss_info_changed 0000000e > [ 10.469748] mt7601u_conf_tx 03 <- 0000 > [ 10.473738] mt7601u_conf_tx 02 <- 0001 > [ 10.477856] mt7601u_conf_tx 01 <- 0002 > [ 10.481980] mt7601u_conf_tx 00 <- 0003 > [ 10.486849] mt7601u_bss_info_changed 00002000 > [ 10.488671] mt7601u_config ffffffff ch:1 > [ 10.504305] mt76_configure_filter changed:0 total:80000000 > [ 10.508327] mt76_configure_filter changed:0 total:80000000 > [ 10.550671] mt76_configure_filter changed:0 total:80000000 > [ 10.616870] mt7601u_config 00000100 ch:1 > [ 10.619449] mt76_configure_filter changed:10 total:80000010 > [ 10.621541] mt7601u_config 00000040 ch:1 > [ 10.692407] mt7601u_config 00000040 ch:2 > [ 10.992113] mt7601u 3-5:1.0: Warning: mt7601u_mcu_wait_resp retrying > [ 11.291819] mt7601u 3-5:1.0: Warning: mt7601u_mcu_wait_resp retrying > [ 11.591524] mt7601u 3-5:1.0: Warning: mt7601u_mcu_wait_resp retrying > [ 11.891230] mt7601u 3-5:1.0: Warning: mt7601u_mcu_wait_resp retrying > [ 12.190936] mt7601u 3-5:1.0: Warning: mt7601u_mcu_wait_resp retrying > [ 12.192790] mt7601u 3-5:1.0: Error: mt7601u_mcu_wait_resp timed out Firmware clearly died somewhere between switch to channel 1 and to channel 2... I made some changes to the FW loading routine, I will try to check the traces later today to confirm that I didn't break anything. > Is it because of "unsupported EEPROM version 0d"? Don't think so. It's just for compatibility with vendor driver, they warn too. All new devices have EEPROM ver == 0x0d though. I plan to ask MediaTek about it in a week or two (Chinese New Year) and remove the warning. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
