Some Banana Pi BPI-R4 BE14 WiFi modules are shipped with zeroed
tx_power fields in EEPROM (2G/5G/6G). This leads to low transmit power
on affected bands.
This overlay provides known-good EEPROM data (including correct tx_power
values for 2G/5G/6G bands) dumped from a working BE14 module.
To enable BE14 overlay, add into u-boot bootconf_extra
parameter: 'mt7988a-bananapi-bpi-r4-wifi-be14'.
You can use example script:
overlay="mt7988a-bananapi-bpi-r4-wifi-be14"
current="$(fw_printenv -n bootconf_extra 2>/dev/null)"
if [ -n "${current}" ]; then
fw_setenv bootconf_extra "${current}#${overlay}"
else
fw_setenv bootconf_extra "${overlay}"
fi
Earlier proposal proposed in [1] was fallback to default values if
invalid EEPROM content is detected.
