[QUOTE="mick66, post: 639780, member: 332848"] Hi all, thanks for the info, I finally managed to bring my DM500 to life again. Following a quick summary of my way doing it: 1) the 100Ohm scheme is correct, BUT cut your jtag cable as short as possible and less than 10cm in any case. 2) both win and dos initialized the cpu and flashed the box. But it seems I couldn't find the right alps image for the win prog so I used the dos one. After successful flashing with jtag_win the box just didn't want to light up, e.g. no green led. 3) I found it annoying matching the right sequence of pressing "Connect" and plugging the power cord with jtag_win, so I build a small switch with a piece of cable that worked just fine (seen on 2nd pic). Also the LPT on my laptop didn't support ECP+EPP so I used my desktop. 4) in the dos app you can set your own MAC address by editing alps2.bat 5) If your box is alive again flash a new linux image right away. I didn't, so half an hour I had to grab the soldering iron again. Some pics added. JTAG for DOS @ [h t t p : / / dvb-upload.com/index.php?action=preview&pid=176965&lang=DE] JTAG for WIN is found here in the forum. P.S: Mods, if linking like above is incorrect pls remove it, rest google for "jtagdm500aio.zip" [/QUOTE]
