Great information on the bootloader @ksschwabe, thank you for taking the time to explain the different pieces.
On the topic of the bootloader- is it strictly necessary to use the PX4 Bootloader? If I have a bootloader for my particular board that’s already able to set up all the device peripherals and jump to the main app, it doesn’t seem like it should be necessary? Though I’m guessing it would take some modification of the PX4 build system to skip the normal bootloader…
Please let me know if I should start a new thread on this, I don’t want to divert the topic too much from @Nicomacoco’s questions. Thanks!
