OV2640 sensor.reset() error

[Vinschni]

I brought those OV2640 modules after i learned that the OV7725 are probably not compatible.

Now with those OV2640 and a new MaixBit board i get the same error as before: We get no camera image and following error on sensor.reset()

error gc0328 detect, ret id is 0xff
[MAIXPY]: sensor reset function is null

Traceback (most recent call last):
  File "<stdin>", line 12, in <module>
OSError: Reset Failed

Any hints what the problem could be?

I compiled the latest commit. It works. Previously utilized v0.3.2.

>>> sensor.reset()                                                              
init i2c2                                                                       
[MAIXPY]: find ov2640

I met the same problem with OV2640 and a new MAiX GO board, can you tell me how deal with?

I solved the problem ensuring to at least using https://github.com/sipeed/MaixPy/commit/b29aa57e6abc899ddc2b55629757897c57abeebe

Hello I am having the same issue as well what do you mean by at least using b29aa57

[Vinschni]

I recommend using / building at least MaixPy with commit b29aa57

Hi! I'm new at this, and I also have the same problem: When executin the next line of code: sensor.reset(), I got:

init i2c2 [mt9dll] Sensor ID:0xffff,req:0x1519 error mt9dlll detect, ret id is 0xffff [MAIXPY]: no sensor Traceback (most recent call last): File "", line1, in OSError: Reset Failed

I've tried reconnecting the camera, also with another firmware version but doesn't work :(

Pls help! Thanks!
