Jtag Help

[safe-cracker]

hi

im trying to jtag my samsung 2100 using a pogo jtag and bke 2.2.

i have the mac mot drivers running in the back ground and the port setting set to epp in the bios.the jtag plugs straight into my parallell port without the use of an extension cable.

im getting the target is not connected error from bke 2.2.

my jtag is set up to use pin 20 as ground, however it looks as though the metal point inside the 2100 is damaged.

can i move the pogo into another slot on my jtag and still get it working?

(i understand i can use any of the points from 4 to 20 as ground)

is this correct?

no i dnt think you can move the pogo to another slot i always use the same slots. just disconnect the jtag and re connect it shld work. if not u might need some fresh solder on the points

Yes you can use pin's 4-20 for ground.


PIN 5 TDI
PIN 7 TMS
PIN 9 TCK
PIN 13 TDO
PIN 2 VCC 3.3V
PIN's 4-20 GND

also make sure the box is in debug mode and the pins are pressed down correctly on board..

tee_111, can you explain how it get into debug mode please?

is it a matter of holding the down key when i get ld20, then let go and watch the box go to snd or ap52?

thanks

if the stb has the latest 3.6 software then you dont need to put the stb in debug just need live feed jtag and away you go
