I read some documents ans have unpacked the mentioned archive :
– kernel is very old
– In fact, no way to install our product directly (if it can be built) : maybe you can add pre-built packages using ipkg (a russian forum mention that), but it needs a special toolchain (this part can be done) to build packages.
– mips device : never tested from my side
– no device to test and you can brick yours (and the cost of a unit is quite expensive)
Unless someone want to try a port and is ready to brick his device, It’s difficult to do something.
We (Rudi and me) can assist if someone still want to try but only for patches submission.
