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! chain.c(149) Part 0 without active instruction chain.c(200) Part 0 without active instruction chain.c(149) Part 0 without active instruction jtag> discovery Detecting IR length ... 8 Detecting DR length for IR 11111111 ... 1 Detecting DR length for IR 00000000 ... 1 Detecting DR length for IR 00000001 ... 32 Detecting DR length for IR 00000010 ... 1 ...
