Hi all,

I've been struggling to read the firmware of a DVR (Digital Video 
Recorder) and program another one which had a bad firmware upgrade. I 
already posted to the forum but got no replies up to now; I guess the 
list is more active.

The device, as far as I know because it has an heatsink, is a HiSilicon, 
model Hi3515, here: http://www.hisilicon.com/products/promotion.html

As much as I could find on the net, this chip has a core ARM926EJS

The flash chip is a Spansion S29GL064N

Using UrJTAG 0.10 #1502:
jtag> cable ARM-USB-OCD vid=15ba pid=002a driver=ftdi-mpsse # Olimex 
ARM-USB-TINY-H
Connected to libftdi driver.
jtag> detect
IR length: 8
Chain length: 1
Device Id: 01010000000001010000010011001101 (0x00000000500504CD)
   Unknown manufacturer!

and 1 to the end

So, can anybody help, please?
