Of course there is a way to put binaries on the devices but I don't think we can find how without the original documentation, mainly because:
1. There is no proof that JTAG is used here. Only the ARM got a JTAG interface on our board and the main JTAG feature is daisy chaining multiple chips on a single bus. Maybe the in2g is initially programmed by an other protocol / bus, even by an homemade simple serial bus. But okay if I have to bet I choose JTAG. 2. The JTAG pins aren't clearly defined, that doesn't mean there are no pins on our board but maybe the pins are one of the many board pads ( approximatly 15 pads and 4 JTAG pins -> impossible to guess even with signal level tests (maybe I'm wrong but even if it's possible this will take a very very long time)). I really think there is no hope about JTAG without proper schematics / boards layout. JD.
