VxWorks 6.9 64-bit driver for 10Gbps Mellanox chip
The client manufactures CPU boards and needed a 64-bit driver developing for a 10Gbps Mellanox Connect-X2 networking chip. Although there was an existing Linux driver and a comprehensive user manual, the source code was (as is usual with Linux), poorly documented and contained a number of idiosyncrasies.
The Linux driver was ported to VxWorks, and upgraded for a 64-bit address space. After a lot of low level debugging and stress testing, we delivered a working reliable system.
