flash chip interface

[dr.zin]

I got the Schmartboard 1.27mm Pitch SOIC to DIP Adapter,I still have to interface that to my usbjtagnt device to try to program the flash so I can get my x2 going again.

[dr.zin]

they lied when they told me the flash chip was a MX25L6406e
It is actually a EN25Q64
I can dump the full chip to see where I fouled up the bootloader,but I can't flash it yet.

when I was editing the firmware I was off by 1 line,so the 1st line in the bootloader shouldn't even be there.
Why the receiver didn't boot.

the chip is actually labeled cFeon Q64 HIP-104 which is used in other receivers if you google it

I also have a receiver that doesn't boot .
My problem appeared when the patch download procedure corrupted .
We need bootloader and electronic scheme to have a chance to fix it .
If you find,please inform me.

recover with a xmodem type program and a .stp file,I believe there was one bundled with the x2 rs232 loader

[dr.zin]

for some reason the 8meg flash won't erase/program.
I was able to put a bootloader/app on a 4meg flash.This may be good enough to boot the x2 so I can get into EZM,then do a hot swap and have EZM load a full flash via rs232.

I rebuilt the 8meg interface and resoldered the chip onto the prototype board and was able to program it.
Got it back into the x2 and works fine now.Pin 7 had to be left floating,contrary to other spi flash chips.

If possible, some pictures would be nice! EB

The interface is apart,for my next project.
