[GitHub] [incubator-nuttx] CityAplons opened a new issue, #7074: Unstable Ethernet connection with nucleo-144:f767-netnsh configuration.
CityAplons opened a new issue, #7074:
URL: https://github.com/apache/incubator-nuttx/issues/7074
I would like to ask if anybody resolve the issue with ethernet stability on a STM32F767ZI chip.
After several successful ICMP `ping` packets the board is starting to lose most of them with two different driver warnings: Bad IP checksum and DROPPED Unknown type: 0000.
I have an improved revision chip and already checked other Errata suggestions. However, `CONFIG_STM32F7_ETH_HWCHECKSUM` with forced `Store and Forward` mode didn't help.

Past this day I figured the problem out. There is a wrong second argument in `up_invalidate_dcache` function in low-level ethernet driver compared to the STM32H7 one. It is already fixed in the master branch 🤦.
