In rt2800.h you have: +#define RF_CSR_CFG_REGNUM_MT7620 FIELD32(0x00ff0000) 8bit mask for register number AND bank id? I think it should be 2ff (10bits) because in rfcsr_write you are doing: + rt2x00_set_field32(®, RF_CSR_CFG_REGNUM_MT7620, word); where the word contains up to 6bits of register number AND 4bits of bank id. So those writes above bank no. 3 are not happening. > Currently wifi interface appears in the system and can be enabled but > `iw dev wlan0 scan' gives no result and wlan0 transmits one packet > roughly in 10 minutes as per ifconfig (ssid doesn't appear in the > air). > `iw phy' output looks like this: > Best Regards, Mikko _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
