Hi there Johnim,

I hope I don't need to flash another drive till the CPC firmware is available but I will definitely try the 5volt lead idea next time I do one :thumbsup:

I just got my Gotek and USB<->3.3V adapter

I can't get it to recognise the device though. When you connect the 5V is it supposed to light the LEDs on the drive? I checked the 5V with a meter ok but the drive looks dead.
 
hi robin if you have the jumper on for flashing mode by the power conector the drive light dont light up but if you remove the jumper they do
 
Cheers John. I'll try again later

Ok, I've removed the jumper and sure enough the digits light up so I know that's ok.

However, every time I try to connect the TX/RX light blinks once and then I get "No response from target....etc"

I've tried the reset but that doesn't make any difference. I've tested the loopback on the USB COM device and that works fine so I'm at a loss as to how to get this thing to flash.

Any ideas?

EDIT: I've unplugged everything and plugged it back in and now I consistently get "Unrecognized device... Please, reset your device then try again" whether I restart the flash tool + reset or not

I'm giving up for tonight. I must have tried this 100 times in the last hour. Something's wrong with it :(

Has anyone else failed to do the programming?

I've tried for another hour this morning and the thing just keeps saying "Unrecognized device".

I'm about to give up. I'm feeling more certain there's something broken or it's protected in some way.
 
Hi what is are you using as xp works best

I use xpmode in win7 64x

Also what drivers are you using for the usb flasher and what dsb flasher do you have
 
I'm using Win 7 x64 with a Profilic USB adapter

Loopback works perfectly

Just tried with XP SP3 compatibility and same error. Can't believe this is so hard to get working!

If I don't reset between attempts I get the "No response from target message" so it appears to communicate and lock the device.
 
Did you add usb in xpmode at the top and when it asks for a reset just remove the red power wire from gotek and replug it in and try again. You did set the right com port other than com1
 
Hi John,

I appreciate your input on this, thanks.

I'm not sure what you mean by "add usb in xpmode at the top"

I'm using COM6 (confirmed in Device Manager and by testing loopback with Putty) Each time I reset I disconnect the 5V supply and reconnect (my wire is yellow :) )

I've also tried various baud rates, reducing and disabling the FIFO buffers but the result is the same. I just can't think what else to try.

Working!!

I dropped the baud rate down to 1200 and it works. No other baud rate will work.

Going slowly but at 12% downloading now :)
 
Great mate there are so many usb versions

Have fun now its done

With the usb add bit .I ment enable usb sharing in the virtual xp look at the pull downs on the emulator
 
Ah, didn't realise you were talking about an XP VM. I set compatibility mode on the .exe

Anyway for anyone else who has issues I am using a Prolific USB on Windows 7. It was the baud rate which was the problem.

It's working perfectly in my A500+

I had done a 90% written Amiga drive emulator written for ARM Cortex chips myself. Never got round to finishing it :picard
 
oh yea the baud rate at 1200 does work in win7 thanks but very slow

i use in xpvm @ 9600 and is quick
are you going to look at

what options have you put in it
 
a1k.ork have found a driver that works fantastic for the pl2303 USB flasher :)
I just read about it here :-

http://cortexamigafloppydrive.wordp...miga-floppy-emulator/comment-page-2/#comments

I just downloaded the XP version, removed the driver I had and installed the new one and it worked great and reliably. I did have to use the reset switch (I forgot to try the 5volt cable to see if that worked too)

There is a windows XP and Vista version, here is the link I read along with the authors name :-

hervemessinger | 1 mars 2014 à 8 h 53 min Which OS & adapter are you using ? It seems to have some problems with some prolific driver version. Some users appears to have found the right driver to use : http://www.a1k.org/forum/showthread.php?t=41293&page=13 (in german).

P.S it works fine at 115200 :thumbsup:

UPDATE
@Johnim,

the removing of 5volt wire for over a second idea works as good as the reset button I used. When first trying to connect via the software it will fail, click OK on the error message and then remove the 5volt cable or use a reset button for 1 second or so and then click next and it should work as it has everytime I tried it :):):):):) Looks like this is the answer we have all be looking for :thumbsup:

Thanks for the info !! My 2303 finally arrived today :D

Took over a month from China but it might save me some headaches in the end :thumbsup:
 
@johnim It was something I was playing with when I worked at ARM in 2010. They very kindly gave me an Mbed http://mbed.org to mess around with. Basically the 90% was talking to the Amiga and sending MFM track data. The final 10% would have been the ADF selector on a HD44780 LCD display. Real life got in the way (doesn't it always?)

Perhaps I'll dig it out again and finish it off.
