Hi All,

This is my first time posting. I needed to use a WROVER module with 8MB external flash so I attempted to compile code from https://github.com/micropython/micropython. While I finally managed to compile without errors I found that I could not import the btree module which is essential for my application. I could not find an option in menuconfig. Can anyone help on how I can compile in btree module support.

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.

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

Thanks for following up...

BTREE module should be built-in. Do you need the support of 8 MB flash? If so, consider trying the firmware linked below, both 8 and 16 megabytes

These firmware only changed the frame buffer module，Added Chinese support and big font support

The btree module is about to be included again for the ESP32. Damien is working on it.

Great that the btree module is going to be included, I will try wangshujun's branch in the meantime.

Btree is included now. You should have it in the daily build tomorrow.

Many thanks to all!

Just to confirm that I have compiled the daily build and I can now import the btree module - problem solved!

Best!
