Thread: JTAG Austar ABS 8776 Help

here is an older pre 2000 firmware for the 8776 - i've heard it works great for CS'ing



regards...

Nice going with the software. I'm having trouble connecting with my JTAG. There was no pins there on the socket and three surface mount resistors are missing. Do i need to solder in these resistors to get it going? I soldered in the pins but it won't connect.

Also what kind of JTAG circuit should I be running. Here is the schematic of the one im using

Thanks, Zeep

no the jtag connector on the 8776 PCB is never populated with a connector just blank solder filled holes - you shouldn't need to add any components to the board

yep the jtag circuit looks fine - should also work with 5 Volt which you can find on several of the components around the card reader, is everything grounded together correctly (computer, JTAG & decoder)

what version jkeys software are you using and does it have the correct ADB-8776 Flash Definitions in it

what is the board version/revision of your 8776

have a read of the old thread:



and here is the jkeys:
