BJL Upload trouble

[ray]

hi there,

 

i just BJL modified my jag and built a cable...the firmware modification works fine obviously, it brings up the debugging screen with its blue border and the whole register dump.

now my problem appears as soon as i try to transfer a file into the jaguar's ram. i'm using the latest bjl uploader (2005) but nothing happens on neither the jaguar, nor the peecee side (i.e. having pressed 'A' the jaggy keeps waiting with the blue uploader screen, without any palette flicker while the pc just hangs into the bjl loader).

 

i've also rechecked the cable connection several times and booted into ms dos 6.22 using an older uploader but i always get the same result...i even tried several settings for my LPT port (bidirectional, EPP, ECP), but there's no cure (.

 

any hints? do you think my pc's parallel port is incompatible/cut down in some way, or am i the one that is mistaken on the user's side?

 

thanks for any suggestions.

 

regards.

Where do you find "the latest BJL uploader" ?

 

Do you know that the real latest BJL uploader is only for Falcon ...

 

 

------------------------------------------------------------------------

with old version

look at your PC bios to see if you are in normal mode

 

look at the line of the loader and the -option like -n and -w

Does your BJL uplader work on TT too? What is the reason it is only for Falcon?

If you start the receiver part on the Jaguar by using FireA (for 8bit) you need to

place the "-n" parameter into the call of the uploader (PC-side).

 

Example:

bjl_load -n -8 colors.jag

 

You can find some more info about the BJL-connection here:

http://www.mdgames.de/bjl_loader.htm

 

You mention that the palette flickering on the Jaguar-screen doesn't occur,

but the flickering only happens if the magic word for the BJL-transfer was

detected in the data-stream by the Jaguar-software. If you have a

unshielded or bad cable, or need to slow down the transfer ("-w") then

at least the LONG-word in the top left corner of the Jaguar's screen should

change it's value (of course only if the 2 handshaking lines and atleast one

data-line is connected properly!).

 

Have you tried a 4bit upload?

I think it must run on a TT machine, i haven't tried because i don't have one, this version of this uploader is based upon the upload routine present in the 'debjagpr.tos' and have been modified (movep killing) for correct use on Falcon with 68060.
