Re: Thomson SpeedTouch 5x6 & 585 EJTAG "De-Brick" Access
Hi DiskAce,
Well, i've found discrepancies already. One ST516
picture to which i linked shows the 4 pins 3 Volts
Console pads and the 14 pins "De-Brick" access but
the European site appears to exchange them! There
is a way to make sure which is which, it happens a
scope trace is included that strongly suggests the
TTL serial port is reached via some of the 14 pins
instead of the four ones but the coulours from the
French text don't match with those on the picture;
unless their orange and my yellow are the same and
both would correspond to pin #8, that is... If it
is so, pin #1 is Tx, pin #4 is Rx, pin #8 is power
(+3.3 Volts) and pin #7 is gound (0 Volts). Also,
they have a 12 pins header were i expected to find
a 14 pins one so i conclude caution is required...
On the ST546 picture, closing up on J3 and J6 will
not allow me to follow signal paths and this means
i'd need to open mine to take even closer shots or
i won't be able to tell where the EJTAG plug goes.
Moreover, the chipset on the ST546 photograph will
be a BroadCom BCM6338, its PinOut may differ quite
radically! I conclude more caution is required!!!
