Kernel 6.8 not supported. Some incompatibilities can be present.

[SevillaFe]

Hello,

I'm trying to install the Akida PCIe card drivers on a Raspberry 5 running Ubuntu Desktop 24.04 LTS and I'm having problems installing the drivers; I'm getting this error :

Kernel 6.8 not supported. Some incompatibilities can be present.

What are the steps to correct this error?

Thank you

Hi @SevillaFe,

Ubuntu 24.04 + kernel 6.8 is a quite fresh combo we had no chance to try before 😊
Note that it comes w/ python 3.12 we are not supporting yet as per https://doc.brainchipinc.com/installation.html#supported-configurations and that I had to downgrade to python 3.11 for the test below.

For the driver build you can refer to #18, as you can see it should then work fine with kernel 6.8:

rchevalier@elektra:~/akida_dw_edma$ uname -a
Linux elektra 6.8.0-31-generic #31-Ubuntu SMP PREEMPT_DYNAMIC Sat Apr 20 00:40:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
rchevalier@elektra:~/akida_dw_edma$ python -m akida devices
Available devices:
PCIe/NSoC_v2/0

This being said, RPI5 is not a device we maintain and I would recommend to use https://brainchip.com/support/ for further assistance. Please provide details about the board you use and how you connect it to the RPI5 reaching out our support team.

Best,
RC

@SevillaFe Have you tried to git clone repo again? Tried it today with 6.8.0-107 on Ubuntu 22.04.5LTS on arm64, and it works fine.
