"mobile net init fail" on MAIXduino #37

Closed KotNitro closed 5 years ago

KotNitro commented 5 years ago

Hello!

I ran into a bug with "mobilenet_v1" example on my MAIXduino - it begins to load model file, but "mobile net init fail" appears on serial port monitor. I tried to find the reason and I saw mbnet.begin(kmodel_name) return value -6. I used different MicroSD cards and model files from your site with the same result. As KPUClass source code is not available (I did not find it), I can't debug it any further. Please help to solve that.

Many thanks! With regards, Maksim

What maixduino version are you using? There was issue that has been fixed https://github.com/sipeed/Maixduino/commit/240bb27d0b53c2ddb246a8bdf2a10692bdc001dc and is merged to v0.3.10

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: https://github.com/sipeed/Maixduino/issues/29

KotNitro commented 5 years ago

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 commented 5 years ago

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 commented 5 years ago

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 commented 5 years ago

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

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
