Hi,

I'm trying to re-flash this 16mb chip with the original contents I dumped
before attempting to flash a new bootloader for OpenWRT installation, all
the flashing of various CFE bootloaders was successful and the last erase I
did was also successful. However this happens when I try to re-flash:

pi at raspberrypi ~ $ flashrom -p linux_spi:dev=/dev/spidev0.0 -c"EN25Q128" -w
EN25Q128_flash.bin --verbose
flashrom v0.9.8-r1888 on Linux 4.1.18-v7+ (armv7l)
flashrom is free software, get the source code at http://www.flashrom.org

flashrom was built with libpci 3.2.1, GCC 4.9.2, little endian
Command line (6 args): flashrom -p linux_spi:dev=/dev/spidev0.0 -cEN25Q128
-w EN25Q128_flash.bin --verbose
Calibrating delay loop... OS timer resolution is 3 usecs, 297M loops per
second, 10 myus = 11 us, 100 myus = 101 us, 1000 myus = 1011 us, 10000 myus
= 10067 us, 12 myus = 13 us, OK.

Chip status register is 0x00.
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).

This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom at flashrom.org if any of the above
operations
work correctly for you with this flash chip. Please include the flashrom log
file for all operations you tested (see the man page for details), and
mention
which mainboard or programmer you tested in the subject line.
Thanks for your help!
