But newer kernels may well have stricter requirements than the kernels 
that worked previously, and these new requirements may prevent the old 
binaries from working. Such considerations may have contributed to the 
dropping of support for MIPS32 in Debian, as I noted. Remember the fuss 
about the flash technology used in the CI20 where suddenly people were 
being told that they should never have expected the flash storage to 
work, and support for it was going to be removed? It could be that kind 
of situation.

I would have to go through my mail to recall the details, and I am not 
currently in a position to do that. It should perhaps be noted that 
Sudomaker might not even be using Debian, particularly since their 
devices are also memory-constrained and probably use a customised root 
filesystem image. So they can build their programs exactly as they need 
for the appropriate kernel version.
