in the chat is fine. I just started a thread to separate from the other ongoing conversation. I am cooking and will be in and out

Thank you, I appreciate it
I'll put the questions in this thread to avoid clogging the main chat:
Q1: I want to program the Feather M4'S SAMD51J19 completely manually, that is completely in C in Atmel Studio, I see the pins for the JTAG, should I do it that way, or can I generate a UF2 - compatible file from my C in Atmel Studio and do the drag-and-drop method?
Q2: What is the lowest power use recorded in standby sleep mode? I realize this depends on clocks, input voltage, uC power domains, etc, but just a ballpark?

you can convert .bin files to .uf2 with a python script. But note that the starting address is 16384 (0x4000). That way you will not change the bootloader. Or you can upload with bossac, used by Arduino IDE.

Thank you! I take that to mean that I need to edit my linker script to begin at 0x4000 so that the UF2 method will continue to work?
Q3: Is there any schematic I can take a look at? I would like to remove the battery charging hardware manually.

No worries, thank you for the help I really appreciate it!

back... The uf2 conversion script is here: https://github.com/microsoft/uf2/blob/master/utils/uf2conv.py
I don't know of anyone who has tried to do this with Atmel Studio, but in theory in should work
if you have more questions, feel free to ask in the main part of the channel since I may not be around
