Dave,
Thank you for your reply.
E.g. I would like to write some  new data into IC flash memory.
So I was thinking about using JTAG. But for that I would need to know SPI a=
ddress.=20
Do I understand well, that the only way how to find out the SPI address is =
to debug the driver=20
or BIOS of that device?

And/or Isn't there any other way how to write data into the flash of that L=
inux embeded=20
device?

Thanks
