kpu_run_kmodel: Result of model too large?

[Myphos]

Expected behavior

I compiled a .tflite model with ncc 1.0.0-fec915fb and try to run it on K210. Unfortunately the model isn't running because the code fails with the following error message:

[..m/runtime_module.cpp:65 (shape_reg)] id < shape_regs_.size() = false (bool)
error: Result too large

The summary of the compiled model is

SUMMARY
INPUTS
0	new_input	u8[1,3,240,320]
OUTPUTS
0	Identity	f32[1,6300,6]

MEMORY USAGES
.input	 225.00 KB	(230400 B)
.output	 147.66 KB	(151200 B)
.data	   2.93 MB	(3072000 B)
MODEL	 402.77 KB	(412440 B)
TOTAL	   3.69 MB	(3866040 B)

The model is fitting in the SRAM and I can initialize it with kpu_load_kmodel(&task, model_data_align) without error. After that I try to run it with kpu_run_kmodel(&task, g_ai_buf, DMAC_CHANNEL5, ai_done, NULL) but this functions results in the error message.

Test code

I attached the model (yolo.zip). I simply replaced the kmodel file in the 'kpu' example of kendryte-standalone-demo with my model.

At least the kpu_run_kmodel function should run without any errors, right? Or am I missing some limitation that I oversaw?

@junze6 更新sdk的runtime了吗,要把你现在用的nncase版本对应的runtime copy到sdk中, 参考这里.
