Build the JTAG as in the PDF below.
JTAG is in the corner of the PCB and is a 20pin connector (no pins, just pads) layed out in a 2 x 10 array.
Pin1 is the square pin.
Connections are as follows:
PIN9 = TMS
PIN11 = TCK
PIN13 = TDI
PIN15 = TDO
PIN19 = TRST
Ground is all even number pins.
VCC is the end of capacitor C40 nearest the processor.
The box must be powered up to be flashed (don't worry about the lack of display or picture)
Flashing with JKEYS
-------------------
Run JKEYS and Detect. Should come up as:
Device ID: 0x1D405041
Device: STi5518MVB-X
Choose the IRD model as 4900
Flash would be 29LV160
Start : 7FE00000
Bytes 20000
Go into flash programmer.
Erase chip first by clicking on Erase in the top right
Flash chip with a working TSOP image by clicking on the top-right Program button.
Flashing with SkyMax UP (Easier!)
--------------------------------
If you are having problems flashing with JKEYS you can also use SKYUP. This is much easier to use.
Click on 2mb (0x7FE00000)
Click Start
Click Erase
Click Write
