Hi All

An issue has been raised on the netxduo repo

https://github.com/eclipse-threadx/netxduo/issues/278

For RISCV-64, ULONG is an unsigned long which means it is 64 bits, which causes the netxduo code to fail, but for other 64-bit processors ULONG is a typedef to unsigned int, meaning ULONG is 32 bits.

At first, I thought that means we just needed the RISCV-64 definition to match those of other 64-bit processors, but I'm not sure if the RISCV-64 is implemented differently to x86_64/arm64 due to hardware implementation differences.

Is the correct way to fix this to make ULONG 32 bits on RISCV-64 or to fix the netxduo so that its comparing with a constant rather than sizeof(ULONG) which is implementation dependant?
