Jtag with CAS3

[leo1352]

does anyone can help me how to JTAG an STB with a CAS 3 Interface device?

First read the instuction of cas3. Is j-tag but not for every stb.

Only for metabox or dm

For other model of stb is not suitable.

Try to use an unbuffered jtag using the parallel port on your pc,also you will need the programms Jkeys and Wall to reset the cpu state to be able to program the flash.You can search for the jtag package for Visionet stb as it contains most of the info you will need.Also you have to find a dump file for your stb to write it back to the flash.

Thanks for the help. I couldn't find the "wall" program for download ,could you please help me?
is it also possible to add some another STB plugins to CAS3 program ,so it would be posible to JTAG more receivers?
when I bought this CAS3 ,it said that it can JTAG STBs ,but it didn't mentione that it could only JTAG 2 receivers!!
