SPI flashing Fundan microelectronics FM25F04

[Ranjan]

Hello,

I am new to flash rom and I am trying to flash the FM25F04 chip. I am using
this programmer https://github.com/JiapengLi/usbprog with teensy 3.2
and it comes to point saying "generic flash chip found (RDID)" but does not
read or write to it.I am doing this in windows. But later I tried the
arduino Due itself as suggested in usbprog but it does not start flashing
into it but gets stuck.

Could someone please tell me how to get this working.

Ranjan
