I’m trying to get the NPU running on the CM3 but it just won’t work.
I’ve remove the overlay “rk3568-disable-npu”, updated the kernel and tried all the examples. I’ve also tried the Debian and the Ubuntu version, but everytime I get the message:
E RKNN: [16:35:36.210] failed to open rknpu module, need to insmod rknpu dirver!
E RKNN: [16:35:36.211] failed to open rknn device!
rknn_init fail! ret=-1
Can anyone help me with this?
Hello
Which mirror are you using?
Which mirror? Don’t know what exactly you are referring to.
You can try to use this mirror,I remove the overlay “rk3568-disable-npu”, NPU is available

Oh, i see.
I was using the one from the wiki:
I will try your one. Seems to be newer. Maybe it helps.
A little bit has changed: when I remove the overlay rk3568-disable-npu the NPU seems somehow to be available. At least the RAM decreased by 512MB.
But the rest did not change. When I execute the examples from the repository:
I still get the error:
E RKNN: [12:50:42.310] failed to open rknpu module, need to insmod rknpu dirver!
E RKNN: [12:50:42.311] failed to open rknn device!
rknn_init fail! ret=-1
Yes, I have successfully run RKNN2 SSD DEMO according to the tutorial
Thanks for your reply. There seems to be something wrong with my board. The WLAN0 device is also not available. Maybe there are some hardware issues.
Hello, I checked your log, have you modified the dts, if not, you need to check the hardware
RKNPU fde40000.npu: RKNPU: failed to get vdd regulator for rknpu: -517
Hi,
I have not modified the dts. How do I “check the hardware”? I do have a microscope. Anything that I have to look at? Or measure?
I mean: I just bought it and it did not work from the beginning.
What is the version number of the hardware?
I didn’t find ModuleV1.31A, I used V1.3 to test RKNPU is available, are you using the Radxa-cm3-io baseboard? Maybe it has something to do with the hardware.
I’m using the Raspberry IO Board. But there seems to be some issues with the CM itself. Wifi used to work in the beginning. But no I just “cant find it anymore”.
