yes this is a bug; see https://github.com/raspberrypi/pico-sdk/issues/762 the next (SDK1.3.1) version of `elf2uf2` will work around this for you. There will be an errata in the next docs release, and...

The intention is currently that you always use INTERFACE libraries. if you statically link the SDK code into a static library, then you will end up with unexpected results. You...

perhaps ``` if (EXISTS ${PICO_TINYUSB_PATH}/examples/dual tinyusb_dual_examples) set(TINYUSB_FAMILY_PROJECT_NAME_PREFIX "tinyusb_dual_") add_subdirectory(${PICO_TINYUSB_PATH}/examples/dual tinyusb_dual_examples) endif() ```

Yup - picotool works around this problem using the EXEC method if you try to download the bootrom.

Bumping to 1.4.0 to review when we update TinyUSB

You just need to use two DMA channels in parallel (you don't need to ping pong). see https://github.com/kilograham/rp2040-doom/blob/c77136a24837a41fe1561778d4563d22679850fb/src/pico/piconet.c#L535

which README?

you should not need to add `sys_check_timeouts` as lwIP in NO_SYS=0 mode has its own timer/task... (maybe not everything is configured correctly tho!?) have you tried rebooting your AP?
