You need to tell what kind of CPU you have. JTAG port is connected properly? The flash itself is not important at all.

Maybe the CPU is the one that has heatsink on it. So we need to find out what chip it uses.

This is MIPS core and if it has JTAG port then USB JTAG NT is very likely can be made to support this device.

If it is MIPS JTAG it is normally 14 pins (standard).
Some has 12 pins or even 10 pins (simplified).

You need to find the one that has pin 2,4,6,8,10 grounded. (Find 14 pin first).
Then it is very likely to be MIPS JTAG.
