LoPy link error

[oldGuyDave]

I am building the latest firmware for LoPy (rev 1.18.1.r1) and I am getting the following error:
LINK build/LOPY/release/application.elf
lib/libfreertos.a(port.o):(.literal.pxPortInitialiseStack+0x0): undefined reference to _thread_local_end' lib/libfreertos.a(port.o):(.literal.pxPortInitialiseStack+0x4): undefined reference to _thread_local_start'
collect2: error: ld returned 1 exit status
application.mk:582: recipe for target 'build/LOPY/release/application.elf' failed
make: *** [build/LOPY/release/application.elf] Error 1

Can anyone tell me what I may have missed?

@robert-hh said in LoPy link error:

pycom-esp-idf

That was the problem. Thanks - everything works and firmware flahses fine.

@oldguydave
I just tried buidling for LoPy here and ti worked fine.

• Did you use the proper pycom-esp-idf library, which a git submodule update --init --recursive after cloning?
• can you try a "make clean" in the esp32 directory and then a new build?
