On a fresh macOS Mojave install, with pfalcon's esp-open-sdk built in a case sensitive dmg with VENDOR_SDK = 2.2.1
I hit an issue when trying to make in /ports/esp8266.

Code: Select all

./etshal.h:9:6: error: conflicting types for 'ets_delay_us'
 void ets_delay_us(uint16_t us);

If I change it to uint32_t it works. In micropython/ports/esp8266/etshal.h:

Code: Select all

- void ets_delay_us(uint16_t us);
+ void ets_delay_us(uint32_t us);

Has anyone come across this?

FYI how I built the esp-open-sdk:
https://github.com/pfalcon/esp-open-sdk/issues/342
https://github.com/daviddpd/esp-open-sd ... 0717a62a28

Interesting...

When I make using docker, it needs to be void ets_delay_us(uint16_t us);. As it is currently in the repo:
https://github.com/micropython/micropyt ... tshal.h#L9

Code: Select all

cd ports/esp8266
docker run --rm -v $HOME:$HOME -u $UID -w $PWD larsks/esp-open-sdk make

When I make using esp-open-sdk in a case-sensitive.dmg, it needs to be void ets_delay_us(uint32_t us);.

Code: Select all

export PATH=$PATH:/Volumes/case-sensitive/esp-open-sdk/xtensa-lx106-elf/bin
cd ports/esp8266
make

OK so, I have figured out why now.
In my case-sensitive.dmg "on the metal" esp-open-sdk, I was bumping the VENDOR_SDK from 2.1.0 to 2.2.1
However... In >= 2.2.0, ets_delay_us() was updated to use a uint32_t!

ESP8266_NONOS_SDK-2.1.0 /include/osapi.h

Code: Select all

void ets_delay_us(uint16_t us);

ESP8266_NONOS_SDK-2.2.0 /include/osapi.h

Code: Select all

void ets_delay_us(uint32_t us);

ESP8266_NONOS_SDK-2.2.1 /include/osapi.h

Code: Select all

void ets_delay_us(uint32_t us);

I know this is an old thread, but I am facing the same issue.

Is there a solution for this ?

I have a fresh build environment using

Code: Select all

ESP8266_NONOS_SDK-3.0.1

Hi @devnull, Not sure about the latest SDK, but the old fix was to find “ets_delay_us” in the MicroPython codebase and replace “uint16_t” with “uint32_t” and build.
