UART bootlog InnoTab/V.Reader
#1
Information 
I have finally figured out the testpads for the UART of the ARM chip inside the Innotab 1 : they are TP4 for TXD and TP3 for RXD
i couldnt figure out a GND (ground) pad so i have opted for one of GND pins of the cart port ( as the pins of the cartridge port are
similar of Innotab 2+).

   

The testpads are really small  so it isn't easy to solder leads to a USB - TTL Serial Cable .
   

   

But finally i could read some bootlog messages:
Code:
