Process to jtag the magnum3300 with 4meg flash.
Unzip to c:\ and follow the 10 steps.
Should work for other sti5105 based receivers with sst39vf3201 flash.
You would have to supply your own full jtag size flash.bin
For 2meg flash you would use the -b SDM in the command line .bat files instead of -b MB385
For sti5119 2meg flash use -b SDM
Erases and programs only.For saving flash dumps use jkeys first.

The circuit on the right is for the TRST,TDI,TCK,TMS.
