"mobile net init fail" on MAIXduino

[chegewara]

What maixduino version are you using?
There was issue that has been fixed 240bb27
and is merged to v0.3.10

[KotNitro]

I use V0.3.9 and I fixed SD Card bug earlier (there was card reading problem), and got the error from topic start after that.
Version 0.3.10 is shown in list in Arduino IDE, but is not actually available (previous versions still could be downloaded):

First of all i can download v0.3.10 without problem, maybe try one more time, and second of all i think your problem is duplicate of this:
#29

[KotNitro]

I have updated MAIXDuino to V0.3.10, but I still see those messages on port monitor:

init mobile net, load kmodel from SD card, it may takes a long time

and after about 10 seconds

mobile net init fail

So, it looks like loading has been started, but crashes a bit later for some reason.
I use mobilenet_0x300000.kfpkg file renamed to m according to code. I also see "Loading..." on LCD, so file was found on uSD and it is not well-known uSD bug.

[chegewara]

Maybe try different card since it is "Loading...", which means card has been detected and file possibly has been found, i didnt try code with option: insert card with no file on it (i am using name model).

[KotNitro]

I tested a number of cards, 16 and 32 Gb, with the same result.
Are there any limitations for card size and file system?

[KotNitro]

Now it works!
In my case it was important to satisfy some requirements:

• MAIXduino version is 0.3.10 (the latest for today)
• MicroSD size is 16 Gb (8 Gb does not work for some reason) and formatted with FAT32 file system
• downloaded mobilenet_0x300000.kfpkg needs to be unpacked as it is actually .zip file!
• unpacked model file name should be the same as in code (single letter m without any extension by default).
  Thanks for help

I have the same problem, I have the appropriate configuration in Maix One Dock W

I changed a 16G size tf card to resolve it
