Problems flashing custom firmware to the nice!nano
I'm compiling a very stripped down example from https://github.com/embassy-rs/nrf-softdevice that should just loop forever and turn an LED on and off. I convert from a binary to the uf2 using this script linked in the adafruit bootloader repository. The command I run is uf2conv.py -c -b 0x26000 -f 0xADA52840. When running file on my binary the output is UF2 firmware image, family Nordic NRF52840, address 0x026000, 42 total blocks, exactly the same as on the ZMK image that works without a problem.

RP2040. Willing to compensate for a solution.
How can I (someone with no electronics or programming experience) configure my own layout using QMK Config and then compile it into a .uf2 file that works on the Sea-Picro with my Ferris Sweep?

RP2040 USB Bootloader?
The bootloader uses the UF2 protocol, which is cleverly designed to allow "drag and drop" flashing over USB mass storage.

STM32F4 Remote Firmware Update Executable Script Suggestions/Help/Guidance
I'd strongly recommend using an application-specific USB bootloader if possible. The UF2 firmware update protocol is particularly slick, as it allows users to upload new firmware over USB mass storage and requires no staging space; if using this is an option, I'd go for it.

Designing end products with option to update firmware via USB cable
The mentioned UF2 standard (UF2 - mdf5 checksum) actually offers the option to specifiy an MD5 checksum. Which is heavier on resources.
