mvidea fs 4000

Post by slugworth »

fta receiver same processor as the viewsat platinum (cx24142) but only a 1meg flash and no eeprom.Also the bootloader section is 65k instead of 130k
using the viewsat config I get
Copyright (C) 2010,2011,2012
USB JTAG NT 0.63
Target: Viewsat
-detect
IDCODE 20920027
Conexant (ARM920)
Found Address= 20000000 AMD AM29LV800BB
Found Address= 20190000 AMD AM29LV800BB
but when I try to tweak the .xml to match the receiver usbjtagnt program crashes.
It uses the spansion S29AL008 memory
any helpful hints?
the ultimate goal is to try to jtag platinum lite firmware into the receiver to see how it reacts.

Send me teamviewer ID and I can take a look.

editing the viewsat.xml I was able to dump the full flash and bootloader sections proper sizes.But when I went to program just the boot the erase showed no progress bar and when I restarted it had put garbage into the entire flash.Now the receiver is dead.I may try the new version I was using v.63
I don't have teamviewer and my connection is too slow anyway.

when you make a .xml from scratch,it doesn't add the
<conexant>1</conexant> after the subprotocol,I had to add it manually or else I get

-detect
IDCODE 20920027
Conexant (ARM920)
Unknown flash type!
Report these values http://www.usbjtag.com/vbforum 5b07,663e

and also it saves it as modem type,instead of DishIrd
now I get

but it still doesn't erase the flash

Most likely you have put the wrong
<Programram>0x100000</Programram>

Try to use "erase" and "sprogram" to see if it fixes the issue.

Your XML does not look right compared to what you are trying to do.

If you do not use teamviewer I cannot help you.
<Address>0x20000000)</Address>
Might be wrong.
Also I think you size should be
<Size>0x100000</Size>

not
<Size>0x10000</Size>

Something else to check flash is blanked after erase.
