Got A Coders Cable...Now What?

[Emrikol]

Ok. I'm new to console programming...and I've been following the DC scene for a while...so I decided to try and start coding.

Well, I got all the cygwin tools built, nice and lovely, and my "Hello World" compiles with no errors.

Then, I buy a coder's cable--and hit a brick wall.

None of the sites I've found have any up to date tools or info. Well, I take that back. I found the site for dc-tool, with the iso for the serial uploader...burned the CD, started the DC...loaded cygwin...tried to upload an elf file, and all my Dreamcast does is say: "Receiving Data"

Am I doing something wrong? Does anyone have any tips or anything? I've found it to be a _major_ headache to try and get a good start in the dreamcast homebrew scene...there's not any real site out there that's got an "all-in-one" solution that's needed for people like me. Although, with the help of some 404's and Archive.org's wayback machine, I got everything but the coder's cable going.

anyways...thanks for your time and help!

Well, youhave to keep in mind that with the coders cable, uploading stuff to the dc takes sometimes alot of time. How long did you let it go?

check your serial port settings, which com port do you have it plugged into ?

$ ~/prj/dc-tool.exe

dc-tool 1.0.3 by <[email protected]>

-x <filename> Upload and execute <filename>
-u <filename> Upload <filename>
-d <filename> Download to <filename>
-a <address> *Set address to <address> (default: 0x8c010000)
-s <size> * * Set size to <size>
-t <device> * Use <device> to communicate with dc (default: COM1)
-b <baudrate> Use <baudrate> (default: 57600)
-e * * * * * *Try alternate 115200 (must also use -b 115200)
-n * * * * * *Do not attach console and fileserver
-p * * * * * *Use dumb terminal rather than console/fileserver
-q * * * * * *Do not clear screen before download
-c <path> * * Chroot to <path> (must be super-user)
-i <isofile> *Enable cdfs redirection using iso image <isofile>
-h * * * * * *Usage information (you're looking at it)

the commandline I usually use is
dc-tool -b 115200 -x test.elf

,since my coder cable is on com1.

Does your dcload screen change when submitting the elf file from


dcload 1.0.3
idle...

to something like

dcload 1.0.3
receving data...
(00000000/000ada2c)

with the first 00000000 incremented by 2 in hex?

here is my output from dc-tool

$ ~/prj/dc-tool.exe -b 115200 -x prj/1st_read.bin

Good Luck

I've waited in excess of half an hour for a 200K file. I know, even at 9600 baud, that it shouldn't take NEAR that long.

Also, this is what dc-tool's output is (mostly...I forget exactly, but I know where it ends...at the file format line):

Console enabled
Changing speed to 9600 bps... done
Upload <hello.elf>
File format is [ELF FILE STUFF] binary, start address is 0x8c010000


and that's it...this is what the DC says:
dcload 1.0.3
receving data...


That's all it does. It's on COM1. I have dc-tool set for com1, I have changed the baud in device manager to 9600. And...also, my CPU peaks at 100% until I manually kill (^C) dc-tool.

I'm out of ideas.
