We have been using open source rt2x00 drivers for our RT3070 WiFi
chipset......according to EEPROM details of Ralink chipset(RT3x7x EEPROM
2.4GHz TX0 & TX1 power setting register --
*Offset b15 ~b8 b7 ~ b0
52h Channel 2 TX0 power Channel 1 TX0 power
54h Channel 4 TX0 power Channel 3 TX0 power
56h Channel 6 TX0 power Channel 5 TX0 power
58h Channel 8 TX0 power Channel 7 TX0 power
5Ah Channel 10 TX0 power Channel 9 TX0 power
But on setting the mentioned offsets in EEPROM using iwpriv (e.g iwpriv
ra0 e2p 52=0809), rt2800lib.c:: static void
rt2800_config_txpower_rt28xx() function does not read the mentioned
Instead it reads 6fh (EEPROM_TXPOWER_BYRATE).....can you please explain
how the open source rt2x00 driver is reading txpower values from EEPROM
and applying the same on to TX_PWR_CFG0...3 registers?
How is per channel txpower getting set?
