I feel your pain, maybe this is of some help (massaging multi-drop somewhat reasonably into something that didn't quite expect it) https://github.com/raspberrypi/openocd/commit/dd9dbe8dc9d5fd7d510a102676e266bf857e5f53 Note single core is fine, but you do...

Note that the Raspberry Pi OpenOCD fork absolutely supports multi-drop and debugging of both cores

why not just make this an INTERFACE library the user can link into their binary?

Yeah, the exact logistics are going to depend on how you are restarting binraries etc... whether you expect to be able to use flash binaries (rewriting the binary you are...

Please reformat that output!

Yes this is a bug. UF2s that do not start on a 4K boundary are not written correctly. elf2uf2 and the docs will be updated in the next release

> I have found that after calling sd_init_1pin(), it is necessary to call setup_default_uart() again in order to obtain any further UART output. Sounds like your SD and UART pins...

I've never actually tried it with USB - there could be a problem there you could try setting PICO_SD_CARD_EXTRA_CLOCK_DIVIDER=8 to see if that helps. Make sure you pico_enable_stdio_uart off if...

There was a silly inverted flag bug in `sd_init_1pin` at one very early point - might be worth checking you have that fix (although it was from feb)

@lurch you had commented this also related to something you were doing
