Thank you for the fast reply. It may be a stupid question but how can I enable an overlay in rsetup ?
[230526] System Release Notice for ROCK 5B
Thank you very much
Hi all, could you please tell me what is the max CPU freq on this system?
It is 2.4Ghz, just off memory some cores are 1.8 and others 2.4
Iāve installed rock-5b_debian_bullseye_kde_b33.img.xz to an nvme ssd with xzcat rock-5b_debian_bullseye_kde_b33.img.xz | sudo dd status=progress of=/dev/nvme0n1 but the image will not boot.

What must I do to actually boot with this image?
Failed to mount ext2 filesystemā¦
So itās better to have fat32 boot partition.
I dd the image to the disk. Why are the image boot files under an ext4 partition? The boot partition of the image file is too small to simple move them there. How was this image supposed to be booted? Since I didnāt create it Iām asking here 
It should be the issue of this image. I donāt know much about it.
The issue is in the SPI bootloader. We should provide an update to it shortly.

Please use the latest ROCK 5B SPI image.

New spi boot-loader.
Is the boot preference now sd-card , usb,nvme ?
How do you enable pwm output with this image? The guide about hardware configuration is not functioning. I need PWM8_M0 to control a 5V pwm fan.
Here is our new documentation. If you want to enable the fan header, you need to change this option.

Subject: Seeking Guidance for CAN Communication with Arduino and MCP2515 Module
Hello everyone,
Iām reaching out to seek guidance regarding my project involving CAN communication with an Arduino using an MCP2515 module. I have successfully enabled the SPI overlay through rsetup on my device a ROCK 5 Model B, but Iām unsure about the next steps to ensure proper functionality.
I would greatly appreciate any insights or suggestions on where I should focus my efforts to make the CAN communication work seamlessly. If you have any experience or knowledge in this area, I would be grateful for your assistance. Specifically, I would like to understand the necessary configurations, libraries, and code examples that could help me establish a reliable CAN communication between the Arduino and the MCP2515 module.
Thank you in advance for your support. Iām eager to learn and make progress on this project, and your expertise would be invaluable to me.
Best regards
This is a known issue, and we are currently working with Rockchip to resolve it.
Thanks for the reply.
What currently the issue ?
And does that means there is, at this moment, no way to enable a CAN communication with ROCK5B ?
Thank you all for your time and any assistance you can provide. Iām really eager to find a solution and make CAN communication work on ROCK5B.
Best regards,
