everdrive freezes while flashing rom

a
I have an intermitent problem where the cart will freeze when writing a rom then after a while it seems ok ?



any thought on solution
could it be my powersuply to the MD ?

 

you mean freeze in begin of flashing process?

 

yes

 

it is normal. it flash memory erase befor write

 

no thats not what i mean

half way through the flash process when the progress bar appears
the rom will stop writing and nothing happens
but then other times its ok

 

oh this bug present on some carts. i fix it in last firmware, so you can try to update firmware or send cart back to me for update firmware

 

firmware is version 9

 

fixed in 11

 

so to update firmware i have to use byte blaster and have a pc with the corrosponding port, which is a problem as i use mac os x

i think i may have an old pc lying arround the garrage
is the update a simple process ?

 

you can buy usb blaster here
but you steel need windows computer because quartus software works only under windows and linux. update process is simple

1) install altera quartus 2 web edition software
2) connect jtag and install driver from C:\altera\10.0sp1\quartus\drivers\usb-blaster
3) run quartus 2 and open tools>programmer
4) press hardware setup button and select usb blaster
5) press add file button and select firmware file
6) put cartridge in console
7) connect jtag to cartridge
8) switch console power on
9) press start in quartus programmer tool

and keep at mind that OS should me updated to last version before firmware update

 

does the connector have to be solder to the everdrive?

 

no. look here

 

Eh, that's not good. Is this something intermittent, or if a card gets this problem, it always happens?

 

this problem present from begin of cart life, not come with time. as far as i know only some of carts with firmware v9 and v4 may show this bug

 

is there anyone in the uk
who could do a jtag os upgrade on this for me ?

i cant justify the cost of the byte blaster simply for this purpose :crying:

they are a bit expensive for what i need it for

 

its a random kind of bug
most of the time the cart works fine
and then wham the rom wont wright to flash
i was wondering if it could be a power issue?
my powerpack is not official
its a telegames powerpack

 

i have buggy cart, which may hang sometime, while flashing, if i use firmware v9, but i also use not official power adapter, so i can't check how such cart work with original adapter.


EDIT: but i can try it with various not official adapters

 

same results on all my adapters :shrug:
i can update firmware and send cart back for free if you could send cart to me

 

evileyecheese, you also need the 10-pin header in addition to the byte blaster. Also, that Quartus II software is free but is 2.7GB!!!! Hey Krikzz, is there any other software than that monstrosity?

 

I have tried to find some small tools for firmware update, but without success
