bricked dvr revival

Сообщение quiksilvr » 05 дек 2016, 04:47

I am attempting to revive my standalone dvr unit that i bricked by uploading the uboot.bin file, via hyperterminal connected to serial port, without specifying a memory address. The board has 2 boot modes EMULATION BOOT & NAND BOOT. It is set for NAND BOOT MODE. below are the specs of the dvr unit.

Manufacturer: ITX Security
Model: ANF1648
Processor: TI Davinci TMS320DM6467T
OS: Linux MonteVista

Relevent Tools that i have:
CCS 4.0
TI XDS100v2 jtag emulator
Null modem cable
WInXP PRO SP3
LINUX Ubuntu

the pic below is what im getting via rs232 port

The last time your boot loader also worked
Now it mean that you clean it?

i messed up the boot loader by sending uboot.img file to incorrect memory address. the maufacturer has sent me this picture about setting boot mode. he did not explain it to me though.

? - Possible it's tune mode for boot selection, from what
Make a photo with these contacts on motherboard.

if you prev. made a u-boot dump so you need a programmer flash and restote boot. It's more quiker!
