Hi Felix,
Please revise your commit: https://dev.openwrt.org/changeset/38486 It is
causing the wifi on TL-WR1043ND v1 to stop working or speed drop.
Please see this ticket for details on my research:
https://dev.openwrt.org/ticket/9654#comment:512
I was able to isolate the issue to this code: static void
ar5008_hw_get_adc_entropy(struct ath_hw *ah, u8 *buf, size_t len)
{
…
REG_RMW_FIELD(ah, AR_PHY_TEST, AR_PHY_TEST_BBB_OBS_SEL, 1);
REG_CLR_BIT(ah, AR_PHY_TEST, AR_PHY_TEST_RX_OBS_SEL_BIT5);
REG_RMW_FIELD(ah, AR_PHY_TEST2, AR_PHY_TEST2_RX_OBS_SEL, 0);
…
}
I have prepared a workaround patch, it resolves the issue, unfortunately the
code it disables is beyond my experience, and it probably breaks your code, so
please check it!:
