i have an elite box stuck in booting. Unfortunately, only the serial port's TX (from the box to pC) works so i cant break into the YAMON prompt. The boot sequence stops at this point:

tango2_enet: ethernet driver for SMP863x internal mac

So i am trying to recover box using the JTAG interface. I followed the details in other posts/sites about flashing NOR on a premuim(make parallel cable, use openocd), but i only got to the point where the on-chip debugger cant HALT the processor. Other users that had reached the same response were unable to solve (hanswurscht is one user from here). Also, the original author of that doc said procedure only worked on Premium, nor Elite. I Dont kniow why.

So, i would like to know has anyone here managed to use the JTAG interace and are there any other users who would like to contribute ideas to this thread in trying to get it to work?.
