The JXD301 dev scene is moving slowly, but pointing to the right direction.
Mithris has managed to disassemble the firmware, and found that Block9 seems to being loaded to 0xffa00000, and thus gets booted first, then it inits some stacks and appears to play around with the MMU a bit. He also found block 2 etc, are loaded into RAM, so the initial bootloader must have an initblock that sets that stuff up, so probably that little program at 0xffa00000 is the one responsible for switching applications, etc.
Meanwhile, RobBrown has received his JXD301 and took some very high detailed inner photographs #1 #2 #3 #4 #5 #6 (warning: each photo is 2.5 mbytes sized!). Interestingly there are a few unsoldered points in photograph #6, which might lead to a communication interface.
