MC60 upload error

[luisfear]

Hi Wiz!

I love your work. I'm having a error, in MC60 with openCPU, can you help me? I tried the versions MC60CAR01A13 and MC60CAR01A12

Hi if this not work use Quectel uploader I not have module for test

[luisfear]

With QFlash v4~5 it works without problems. In PlatformIO it works on the serial monitor. But I would like to be able to upload the code from PlatformO but I don't understand the scripts.

def openApplication(self, fname, check=True):     
        ASSERT( os.path.isfile(fname) == True, "No such APP file: " + fname ) 
        self.app_name = fname
        with open(fname,'rb') as f:
            app_data = f.read()
        app_size = len( app_data )
        if app_size < 0x40:
            ERROR("APP min size")
        if check == True:
            if app_data[:3] != "MMM": 
                ERROR("APP: MMM")
            if app_data[8:17] != "FILE_INFO": 
                ERROR("APP: FILE_INFO") 
        return app_data

ERROR: APP: MMM

openApplication() test Mediatek header at bin file first bites if QFlash work with your bin app file - this error is strange....

[luisfear]

So I understand that the error occurs in the bin verification and not in the upload process itself. Do you have any idea what I can do? What can I try to find out the problem please?

[Wiz-IO]

open compiled app/bin file and look for MMM & FILE_INFO

[luisfear]

The .bin file is correct MMM
@ FILE_INFO


If I make this change in MT6261.py, it passes validation (b')

if app_data[:3] != b'MMM': 
       ERROR("APP: MMM")
if app_data[8:17] != b'FILE_INFO': 
       ERROR("APP: FILE_INFO") 

But I get another error

python 2 3 ?

[luisfear]

My platformIO is using its own version, 3.9.4

[Wiz-IO]

if MMM... FILE_INFO exist... look strange btw: the script is reverse enginering of mediatek/qflas flash tools

[luisfear]

But as I said before, it only passes the validation of MMM and FILE_INFO if I make this change

'MMM' -> b'MMM'

Is there any possibility that the error occurs in the pyhton script when reading the generated binary?

[Wiz-IO]

if bin file work with QFlash - application is OK

[luisfear]

Thank you for your assistance Wiz, you make a very commendable effort, so for the moment I will use QFlash and maybe with some luck, in some platform update in PlatformIO it will be corrected.

[Wiz-IO]

YW yep - I need module for test...
