If The device is not responding front buttons or flash cable
Unfortunately, , the solution is Jtag programmer UM-FT2232H
It is recommended that it be performed by a technician who has the necessary equipment
This file contains the necessary files and instructions For processor 7111 only
Ok,
I will keep it in mind
I have a USB-SERIAL rs232 ttl, but I see that the gm990 comes with a DB9 connection.
Is it possible to connect a usb serial ttl, in the same connector that is on the board?
I mean the one that uses the DB9 connector
If so, is there a schematic to know where each connection goes (rx,tx,gnd,v+)?
Thanks in advance.

Hi
I have connected a USB serial rs232 to my golden 990
with the corresponding speed, the terminal doesn't show me anything, only strange characters (attached picture)
On the front LED, when I turn on, it only shows 00:00, and as the minutes go by, it adds up, like the time.
no key combination works, neither leaving OK pressed, nor anything else.
it seems that the only solution is the JTAG programmer?
Thanks in advance.
