@villivateur there is merge commit in your PR. We do not allow merge commits so you will need to remove that. We also only allow one commit per subsystem/directory, so you will have to split out the AP_Bootloaders, and bootloader files into two different commits with appropriate names.

@rishabsingh3003 The problems are fixed, please review again, thank you.

Some minor changes. Also needs a README

[Hwurzburg]

Readme should provide this information and also images: https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_HAL_ChibiOS/hwdef/X-MAV-AP-H743v2/README.md

Commit names should have library prefix, ie Tools: add AET-H743-Basic bootloader, etc.

[villivateur]

I've made some changes and added the README. Please check again.

I really think you should add bdshot to PWM3-10, feels like that might suit most users, but your call

nice board!...I suggest you send a few to DEVs like PeterBarker, AndyPiper, (maybe myself) for future support facilitation
I have several other requested changes

A new design with the same pin out is on the way, some changes are made for easier use. We would definitely like to send it to all of you when it passed all tests.

[Hwurzburg]

Great, let me know when you makes changes here and want a re-review

[Hwurzburg]

Also, what are the Cfs7 aand Rfs7 pins?

That's a mistake from our PCB designer. It should be CTS7 and RTS7

[villivateur]

I've fixed most of your review. Please check. Thank you. @Hwurzburg

I've test the code on my board. It works well.

When it passes your testing I will mark it for Devcall review and merge...thanks
