EVK-MIMXRT685 eIQ Glow for RT685 Lab CIFAR-10 example build error

[tugrulyatagan]

Hi,

I am following https://community.nxp.com/t5/eIQ-Machine-Learning-Software/eIQ-Glow-Lab-for-i-MX-RT/ta-p/1123119 eIQ Glow for RT685 Lab.pdf file step-by-step. I have installed Python 3.8 and Tensorflow 2.4. I have imported the evkmimxrt685_dsp_cifar10_demo_cm33 example and I have created the mnist.h, mnist.o, and mnist.weights.txt glow_bundle files as explained in the lab notes. However generated mnist.weights.txt size is too big (~2.5 MB). Thus, project cannot be compiled at step "5 Run Glow on the RT685" because generated mnist model doesn't fit to the device. I did what the document said and here is the result. Did I miss something?

Hi @kerryzhou,

I am using RT685 SDK 2.9.0. I was following https://community.nxp.com/t5/eIQ-Machine-Learning-Software/eIQ-Glow-Lab-for-i-MX-RT/ta-p/1123119 eIQ Glow for RT685 Lab.pdf since I am using RT685, not RT1060. In this lab hand out dsp_cifar10_demo_cm33 example is used for demo.

However in the RT1060 eIQ video you sent glow_lenet_mnist example is used. But there isn't glow_lenet_mnist example in RT685 SDK. There is dsp_lenet_demo example and it is completely different.

I check the dsp_cifar10_demo_cm33 project settings and there isn't any FLASH option.

Thanks,

Tugrul

Hi @tugrulyatagan 

Please check my attached project, it contains the flash, but my project is imported from the new SDK2.10.0, you can test it on your side, and add the code again, whether you still have the RAM overflow issues or not?

Wish it helps you!

Best Regards,

kerry

Hi @tugrulyatagan 

  Please also tell me which SDK version for RT685 you are using?

  I will test it on my side.

 BTW, do you watch the video?

https://www.nxp.com/design/training/getting-started-with-eiq-ml-software-for-glow-neural-network-com...

From your build result, seems the file memory location issues, all put in the SRAM, do you select the project build in the RAM directly? Do you enable the flash?

But your code didn't have the flash memory.

So, please check the configuration again.

I check the video, the build result is:

You can find it also use the SDRAM and the flash.

So, please check the configuration again.

Best Regards,

Kerry
