## WiFi Firmware
 
### D80/D40X2
- shortgi & AMPDU bugfix；支持 mcs10/11 功率限制&rssi loss配置
- fix rftest KE_EVT 问题；优化电容校准，取最大3个peak值，提高多次校准结果的一致性；setchan (ap start/sta join) dpd之前增加loft校准
- fix 未校准频偏芯片0度启动时，目标值 target=0 的问题
- 调整2.4G ofdm low rate 功率校准
- 优化 tbl_diff_cal
- 更新带SAW的情况 2.4G triangle mask 配置；DFS port；fix 非信令温补晶体频偏目标值更新
- 更新ipa/ilna 校准配置，根据是否bt coant模式配置 wf_pu_lb_0_avdd_trxsw，解决coant模式下wifi配置影响bt发射功率的问题；rf_calib_req/cfm 新旧版本驱动兼容，避免驱动内存越界导致系统挂死；autorate速率协商 trial rate for legacy
- 增加使用SAW的情况下 配置2.4G 三角波参数，支持驱动使能 ‘USER_RF_WITH_SAW_EN_FLAG’
 
### D80D40 T/H 
- FLASH_FW bugfix; 20H clkgate disable SLP_LDO_PD_EN，提高稳定性
- SET_TX指令设置max pwr为负数时，修复pwrctrlinfo设置错误，避免出PHY_ERR；FLASH_FW mm timer超时return bugfix
- wifisettings增加IPA cal disable接口；rftest/fmacfw通过userconfig 配置 xtal cap的情况下，默认使用常温校准等级，目标值随当前温度更新
- fix rftest KE_EVT问题；更新BT/WiFi 共存配置，fix 5G band AP beacon功率低的问题（错误配置fix tx gain)
- 合入BYD修改（邻道抑制），更新agc_ram + 5g 80M AGC table, freq div when setchan
- TX aggr fix er106 err；更新 asic ver判断，不再列表里面识别为新版本，匹配 >= U0x；增加 srrc 4；rftest set_txtone 参数支持 amp/txgain；rxdc 校准结果支持驱动读写，可减少校准时间；20H 5g ch106 midrate txgain map增加2dB；20H 5g ch42 txgain_map 信令固件 与非信令同步
- 增加 txpwr addition 2x 配置，存在efuse或flash，在2.4G/5G band调整功率
- 修复 20H 5G 电容校准后 low/mid rate txgain_table dtmx_tuning_cbit 设置，2024/12/30之后的都存在问题；wifi_settings.user_ext_flags 增加 loft/capa/pwr disable flag
 
## Tools
- **wifi_test** export WIFI_TEST_CHIP=<chip_type> to change CHIP_SELECT
- **wifi_test** compatible with display on different platforms
