If we were to write such a bootloader for NuttX, would it be preferable to: 1) Have a bootloader that puts the RP2040 into BOOTSEL when it detects something like 1200 baud on a UART line 2) Have an application/NSH command that when run reboots the RP2040 into bootsel 3) Expect some kind of special bytes over USB to enter BOOTSEL My thought is that with 2) we could flash the Pico manually once, and then always be able to reboot into bootsel to flash more configurations, which would be suitable for creating test-farm setups. I think 1) will be inconvenient because it requires a UART connection (as opposed to just a USB connection which is used for both powering and interacting with the RP2040 in a lot of these boards) and I think 3) would be complicated to get right/integrate + require some special byte sequence known in advance and sent by the host device. -- This is an automated message from the Apache Git Service.
