Zephyr Build Failed

Post by craigzyc » Mon Oct 08, 2018 1:15 pm

Any idea what is wrong with my zephyr build?
I can build and flash zephyr examples and if I used ./make-minimal it will build and flash but the full build using the following fails:

Code: Select all

make BOARD=nrf52840_pca10056


Code: Select all

I tried a bunch of variations, and the only combination of Zephyr & micropython that worked was :


zephyr 1.11 ( ZEPHYR_TOOLCHAIN_VARIANT=zephyr )

http://github.com/pfalcon/micropython is kept in buildable state with Zephyr master. Zephyr 1.11 is unbelievably old. MicroPython upstream should be buildable with the last Zephyr release.
