Hi all.
After a lot of reading, head scratching and swearing, I got my DM500 jtagged successfully. It recognised the corrupted bootloader, and flashed itself without problem.
My problem is, I cannot, and never have been able to connect via the rs232/null modem cable, and therefore, cannot flash an image into the box. When I got the box, it would not connect.
I have tried:
Four different versions of dreamup, including the patched one.
Three computers 2 pc's 1 laptop with usb/serial adaptor.
Every com port available to me on any of those machines.
Two different null modem cables, both brand new.
I have also tried FTP'ing into the box, but as yet, it does not connect via IP. Ditto any other means of connecting via IP, telnet/http.
Where am I going wrong, is there any other way of connecting?
Is it possible to flash an image using jtag, or any other flashing tool, or shall I go and buy another null modem cable, and try all the various com ports/computers/cables/adaptors again?
Has anybody else ever had a DM500 that wouldn't connect via rs232? I have had the box apart, and checked the null modem cables from pc to the PCB in the DM500 using a meter. All are ok. The rs232 socket is fine, the plug is in the board properly etc.
Thanks in advance
