Uploading software to custom Pixhawk-like hardware

Posted by Grzegorz Wójcik on January 28, 2017 at 9:41am

Hello,

lets say I designed my own layout of Pixhawk hardware. It is based on Pixhawk schematics, so it has the STM32F4 as well as the STM32F1 microcontrollers and other components (more or less improved). Now I want upload the arducopter 3.4.4  firmware (or any other).

It is not clear to me how do I upload software (for example Arducopter 3.4.4 quad)

1.Do I have to upload some kind of a bootloader before I upload for example AC 3.4.4 via Mission Planner?

2.Where do I find STM32F1 (the coprocessor) most recent code/hex files?

Thanks in advance!

    I have uploaded the firmware succesfuly. Just had to flash the proper bootloaders for processors, ie. 

    STM32F1: px4io_bl.bin

    STM32F4: px4fmuv2_bl.bin

    Now I can upload the firmware (eg. AC 3.4) via Mission Planner and connect with my board. HOWEVER now I have other problem: every time I power up my board I have to press the Safety Button, otherwise the program wont start. I have read that Pixhawk software had this issue some time ago. Does anyone have solution for that? Is this related to the processors configuration?
