Flash SPR F3問題

我有塊SPR F3，想flash inav，硬係去到一半verify唔到就霖跟住入唔番，要short 住boot pin去flash番個cleanflight先用得返。另呢度都有問題，要較到19200baud，仲要一直short住boot pin先成功，吾可以好似人地video咁開始flash就可以鬆開boot pin，且咁樣淨係可flash番個cleanflight，flash inav唔得。
我睇過外國forum話要有stm32 bootloader driver先得，但我幾部腦（全部win 10 / 64）全部都冇stm32 bootloader driver，就算搵zadig都load唔到個stm32 bootloader driver。我睇外國forum好多人都有同樣load唔到個stm32 bootloader driver嘅問題，但冇解決辦法。



想請教：
1 我flash 過程有冇做錯？
2 係咪一定要有stm32 bootloader driver先得？而係咪要win 32先有，64冇？

1 我flash 過程有冇做錯？

select Full chip earse
select Manual Baud rate to 57600

Then U can flash it

2 係咪一定要有stm32 bootloader driver先得？而係咪要win 32先有，64冇？

No need

多謝師兄指點，Flash成功！

SPR F3 play inav is very good, better than Naze 32

Moreover, if U change the YAW 900 then U should also align the Mag to CW 90. However, U cannot Alt-hold. This is my experience.
This is my experience and for your information

If U have time , we can play together, I live in SSPO

Ching留意下！我試了inav 1.1RC2，有d奇怪behaviour (hover緊但架機自已走,看blackbox log,好似gyro有異常變動)！之前用1.0.1 + sensors saturation fix，一直冇問題！可能因為inav1.1係大改，要測試更多！

今日再試，因inav 1.1 轉用LuxFloat PID controller，用之前settings細改唔ok，只好tune過！玩了兩粒電，暫時尚可接受，遲d再tune！

喺flash inav1.01 後噚日第一次飛，乜pid都冇郁過，隻機升起眼高冇問題，跟住一收油摩打即停，隻機半空好似舊石咁跌落地，即刻俾油彈番高佢，發現雖然㗎機唔使1/3油門已升起，但一收到1/4油門油摩打即停，如是者隻機升吓跌下越走越高，第一時間搵草地跟住盡控佢喺最低高度韃返落嚟，爛咗個冬菇殼有驚無險。check返發射throttle冇curve/expo 直綫一條，真係唔明點解，最衰又冇帶電腦得隻電話睇唔到blackbox，為繼續玩即刻用電話flash返cleanflight繼續玩（唔係要返屋企放9排電），隻機又冇問題喎。想問問各位師兄，有冇遇過inav1.01好似咁1/4throttle摩打即停？

inav 有兩個CLI variables，可能有關:
https://github.com/iNavFlight/inav/wiki/iNav-CLI-variables
nav_mc_hover_thr         Multicopter hover throttle hint for altitude controller. Should be set to approximate throttle value when drone is hovering.
nav_mc_min_fly_thr         Max throttle value treated as one of the conditions for landing detection. Must be sufficiently low to guarantee the "not flying" state even with full battery, but high enough for Altitude Hold controller to reach it.

還可試下唔上槳，連上Cleanflight Configurator, 開機推下油門，看下摩打係幾多油門會停！
另要睇inav setup checklist！ https://github.com/iNavFlight/inav/wiki/iNav-setup-checklist
