We are looking for a Linux Kernel Developer, ideally with experience of the Freescale [url removed, login to view] ARM926EJ-S core. The current project is to solve a hardware issue on the Embedded Arm TS-7670 Rev D (256MB) units using U-boot.
Hardware being used: [url removed, login to view]
We are currently seeing an issue where the Freescale FEC PHY driver [SMSC LAN8710/LAN8720] on the 4.4.1 kernel has a “flapping” (repeated up/down state on the Ethernet adapter) issue with a small percentage of the devices.
The current image being used is:
[url removed, login to view]
The project is to either recompile or compile from scratch a kernel that fixes the “flapping” issue and produce a working image for the TS-7670 Rev D units. There are new versions of the [url removed, login to view] MAC+FEC driver+SMSC PHY that can be attempted. It would be preferable to continue on Debian Jessie but a build based on any of the RedHat variants would also be acceptable.
The manufacturer provides a Debian Wheezy image with the [url removed, login to view] kernel that has this driver issue solved. Taking the driver from this source, recompiling the 4.4.1 kernel with this driver and rebuilding the disk image would be the most preferable route. If required by the developer, a current stable or longterm kernel can also be used.
