well, that's not due to btree. Did you update esp-idf to a compatible version? see this thread: https://forum.micropython.org/viewtopic.php?f=18&t=9820 If you don't have any local modifications, you might want to just delete esp-idf and micropython and restart from scratch. Sometimes that's the fast...

"a commit" in git terms is a identifier which points to a specific snapshot of the git history. For example, master always is the most recent commit, but if I pulled master yesterday and you pulled today, you'd have an updated version of the code. We can speak about the exact same version of the cod...

yeah, it is. Did you make clean before hand? which commit are you using?

It's a key value store partitioned into namespaces accessed via labels. >>> nvs_area = NVS('label') >>> nvs_area.set_i32('key1', 100) >>> nvs_are.set_blob('key2', b"binary data") >>> nvs_area.commit() >>> machine.reset() >>> nvs_area = NVS('label') >>> nvs_area.get_i32('key1') 100 >>> x = bytearray(...

Waveshare is busy = 0, idle = 1

BUSY Busy state output pin (Low for busy)

so it should be waiting for high, not low.

seems like the lib/berkeley-db-1.xx isn't getting picked up. I couldn't find a quick solution, and i suspect it needs to be adapted for cmake

reproduced.

Looks like it's getting compiled, but I don't think it's getting linked. If I had to guess, the transition to cmake overlooked this.

I'm poking at it, but maybe worth raising an issue on GH.

I assume you know this, but this is not really a good idea, you're going to end up in a boot loop you can't get out of without erasing the flash. I'm curious why you'd want to do this, and specifically in boot.py rather than main.py? That being said, looks like boot.py is handled slightly different ...

if you can import, if you can't import anything, you probably can't use other tools either.

maybe try: to overwrite it in place.

try using the full path to the cmake file, as noted in the PR. micropython/ports/esp32$ make USER_C_MODULES=/full/path/to/micropython/examples/usercmodule/micropthon.cmake I just did it, and the cexample worked fine for me. make sure you make clean / idf.py fullclean and remove the build directories...
