load error:2015 when trying to load model with kpu

[Balocre]

I've flashed a model compiled from onnx with nncase 1.0 CI but I get this error when trying kpu.load(0x300000) :

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: [MAIXPY]kpu: load error:2015, ERR_UNKNOWN

Any idea what could be causing it? The model I compiled is the one described here : https://github.com/kendryte/nncase/issues/248 . I've tried several variations with different op, but nothing worked.

I've also tried with and without --quant-type option too, just in case, but same error

I just tried with kpu.load_flash(0x00300000, 0, 0, 0x4000) and I get :

SPI freq 16384 Hz
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: [MAIXPY]kpu: load_flash error:2002, ERR_KMODEL_VERSION: only support kmodel V3/V4 now

The version of MaixPy I use is maixpy_v0.6.2_54_g897214100_minimum_with_kmodel_v4_support.bin so V4 should be supported

@Balocre Have you solved the problem yet?

@Balocre Have you solved the problem yet?

The issue is that I compiled my model using nncase CI version which outputs kmodel version 5 files. So I am working with kendryte SDK for now, until maixpy supports V5 (which might be not so soon imo)..

@Balocre Hi, so the answer is use the kendryte SDK, and your model can run on the k210 now? tks

I have been able to load the model without errors and get it running without crashing, but I am unable to confirm it was working properly as the MaixDuino camera model I have (gc0328) is not supported natively by the SDK, I have been trying to port the driver from MaixPy, but I couldn't get the camera to work and i have no idea why.

ov2640 (the former model of camera included in the Sipeed MaixDuino kit) worked out of the box with the drivers provided in the SDK, but I stopped working with the MaixDuino for now because the developers of MaixPy don't really seem to care about the issues, and their code is an absolute nightmare to read.

@Balocre Thank you for your replying. Seems like the own customed model can use on C sdk, but the other firmware is not support like camera. I use Maxiduino too. So what's the next board you use to run your program or you give up?

I will be developing on Nvidia Jetson, I will check back later if by miracle MaixPy has been updated
