Compilation error conflict with zephyr and gccarmnoneeabi toolchain?

1

Hello, Can’t solve this part. It seems framework-zephyr libs is conflicting with gccarmnoneeabi toolchain. Tried reinstalling and installing platformio but doesn’t work. My project compiled succesfully before after how many months this happens (didn’t edit anything with my code) .
TIA

I’ve seen this happen when the zephyr/prj.conf specifies two C libraries to be included (libc and libc_nano). What’s the content of your zephyr/prj.conf?

Wow thank you very much, that solves the problem. I wonder why it works before or some internal upgrades happened. Btw for curiosity what if I retain the libc and discard the libc_nano instead, how can I do that?

CONFIG_BT=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT_SMP=y
CONFIG_BT_DEBUG_LOG=y
CONFIG_BT_DEVICE_NAME=“xxxxxxxx”
CONFIG_ADC=y
CONFIG_ADC_ASYNC=y
#CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y
#CONFIG_NEWLIB_LIBC=y

I think per https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_NEWLIB_LIBC_NANO.html?highlight=libc_nano you just give it CONFIG_NEWLIB_LIBC and never any of the CONFIG_NEWLIB_LIBC_NANO options.

All working again. When I removed the LIBC, serial debug prints don’t work anymore and the device won’t advertise anymore. What I did is I returned the commented out LIBC and added this option. All working again. Thank you again for the help.

CONFIG_NEWLIB_LIBC_NANO=n
