Does DK2 include NPU (galcore.ko)?

[ChipHead]

Recently, I bought STM32MP1 DK2 board. Does DK2 board include NPU (Neural Processing Unit)? Can we use ​the NPU device via galcore.ko (Linux kernel module) to run deep learning network models on the DK2 board? Welcome to any hints and comments.

Hi @ChipHead​ 

No STM32MP15 does not include NPU.

Dear Olivier,​

Thank you for your reply. I thought that STM32MP157C (DK2) include a Amlogic/Viavntea NPU because I could see a galcore.ko file on the DK2 board as follows. Is it incorrect? If the board does not include the NPU, what is a goal of the galcore.ko file on DK2 board?

For example, ​

root@stm32mp1:~# modinfo galcore

filename: /lib/modules/4.19.94/extra/galcore.ko

license: Dual MIT/GPL

description: Vivante Graphics Driver

alias: of:N*T*Cvivante,gcC*

alias: of:N*T*Cvivante,gc

alias: of:N*T*Cst,gcnanoC*

alias: of:N*T*Cst,gcnano

​ ... omission....

And, I attached a figure file that describes different features among board models of STM32MP1. As we can see, DK2 (STM32MP1) board includes 3D GPU feature compared to others. I thought that the feature is related to the galcore.ko file.

Hi @ChipHead​ 

Yes your're right, galcore.ko is the driver for the Vivante GCNANO GPU inside STM32MP157 but does not include NPU.

@OlivierG, Got it. Thanks. ​
