Hi all.
I have trouble with my DVR.
After failed update of firmware, my DVR didn't start.
When I connect rs-232 I see in terminal that u-boot can't execute commands.
It show me command line and on all commands reply:
"Unknown command try 'help'". Also same reaction on 'help' and '?'.
Is it possible recover u-boot throw UART,USB or something else when u-boot is broken?
May be processor has some mode when it can get firmware from UART when start?
I have firmware.bin and u-boot.bin.img.
