Make file error

[karincalab]

Hi,

Thanks for your great project. But I couldn't get it worked. I always get this error

FW build/rboot-hex2a.h make[1]: /opt/esp-open-sdk/esp8266/esptool2/esptool2.exe: Command not found

I am not a linux guy, but I am using a ubuntu VM. I know the esptool2.exe is there but it is not compiling it.

Could you please help on this?

Thanks.

In the raburton/esp8266 checkout directory from git ...

cd esptool2
make
cd ../rboot

Then in rboot ... modify the makefile (or probably also at the top-level, but this should give you the gist)

diff --git a/rboot/Makefile b/rboot/Makefile

As above, and remember that if you're on linux the compiled esptool2 will not have have an extension (so remove .exe)

execvp: /opt/esp-open-sdk/esp8266/esptool2: Permission denied

You appear to be trying to execute the esptool2 directory instead of the esptool2 compiled within that directory. You probably want to be running /opt/esp-open-sdk/esp8266/esptool2/esptool2
