[bellad]

Hello,

it's possible to run mpy file with upycraft ?
if yes , how to ?

ValueError: incompatible .mpy file

thank you

The versions of the firmware installed on your board and mpy-cross do not match. That's what the error tells.
Which firmware version do you have on the board, and which mpy-cross are you suing?

[bellad]

version firmware : esp8266-20190125-v1.10
mpy-cross.exe : Micropython v1.11 on 2019-09-15 ; mpy-cross emitting mpy v4

i have changed : esp8266-512k-20191219-v1.11-671-g0d82f5d8c.bin
it's the same !!

Code: Select all

>>> exec(open('./chauf.mpy').read(),globals())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
SyntaxError: invalid syntax
>>> 

I don't know if I'm doing the right thing

I updated mpy-cross.exe here https://github.com/robert-hh/Shared-Stuff to a today's build. Then it should match.

I don’t think exec() takes mpy content. Have you tried running it using import chauf?

[bellad]

thank's , i will try mpy-cross

Christian , my prog chauf at wihle true , if i do import chauf , how to after for the start ?

[bellad]

hello Robert
i've updated with your myp-cross ,same
i think i idoes not do well
can you tell me how to ?

[Roberthh]

I agree to @Christian Walther, in that exec expects python source, not pre-compiled files.
At least,

import chauf

should run the file chauf.mpy.

[bellad]

ok , thank
i wil try with 'print' , because nothing is happening and I see nothing
i can't try with chauf.py because

Code: Select all

MemoryError: memory allocation failed, allocating %u bytes

Christian , my prog chauf at wihle true , if i do import chauf , how to after for the start ?

I’m sorry, I don’t understand this sentence, can you rephrase? (Or – “chauf” sounds French – try in French?)
