Hi Stefano,

Unfortunately, this is a component that zephyr maintains, and we do not have detailed knowledge about this specific driver, so I would recommend that you ask the zephyr community about this instability:

Kind regards,

Hello,

Thanks for your reply. The performance does not change when i disable logging. When i reduce the spi-max-frequency it also does not change anything.

Kind regards,

Stefano

Hi,

Does the performance change if you for instance disable logging?

I also see that you have setup 8 MHz SPI speed, which can be problematic if you use longer wires to connect to your wiznet ethernet module. Have you tried reducing the SPI speed to see if this helps stability?

Kind regards,

Håkon
