Salincer: I believe you are having a very common problem with the JDM programmer.
A few things: If you have a multimeter, check the voltages on the pins of your serial port. They need to be +/-13VDC in order for the JDM to produce the programming voltage needed to program the chip.
Also, some windows versions do not like these chip programmer softwares using the serial port. There is a file called portio.dll that you can google (with jdm also) in order to find help with that.
If you are not connecting to the chip at all, the software will say it succesfully erased a chip, and all you can read back is zeros. A blank chip is actually filled with 0x3FF as blank space. So dont let that fool you in thinking you are connected to the programmer.
Also, check your serial cable. Some cheap serial cables only have 3 wires in them and the JDM needs a complete 9wire pass-through extension cable.
Good luck.
Hey, thanks alot on the help. Im logging everything, and trying to get it to work on a older computer.
11V from 3rd pin(ground) and 5pin (Pos.)
Hardware test with chip in.... ERROR -> Hardware is not responding
Hardware test with no chip in....Opening COM1. Hardware Ok.
click "READ ALL" Button. 100% progress..read 2048 words, press accept and everything is 3FFF
Then i click VERify all and 100% complete.
Open Sleeper.hex
Program all
Detected -> UNKOWN, device erased, programming Code- 2048 word, 0% and then "ERROR -> Writing address 0x000000 written : 0x2883 Read : 0x3ff
Erase all > device erased.
Gahwd i love this CPU- 534 MHZ.
Its in JDM Programmer, COM1. I have the right chip selected.
I ran over the schmatics, built it twice. oh and led status:
When plugged in USB w/o serial and w/o chip, all lights come on
When plugged in USB w/ serial and w/o chip, only power light comes onbut the MOSFET will if i read/write
When plugged in USB w/o serial and w/ chip, only power light comes on but the MOSFET will if i read/write
When plugged in serial and no USB, no light come on...but the MOSFET will if i read/write
