Re: [flashrom] flashrom support for Spansion S25FL128S

Hi Idwer

I had fixed the compilation issues and could generate the binary.
I tried to read the bios chip first, but it does not seem to recognize S25FL128S

(1) It lists the chip as supported:
flashrom# ./flashrom --list-supported | grep S25FL128S
Spansion      S25FL128S......0                     16384  SPI       
Spansion      S25FL128S......1                     16384  SPI

(2) However when it is specified with --chip options, it says not supported or unknown.

flashrom# ./flashrom --chip S25FL128S
flashrom v0.9.8-rc1-r1883 on Linux 3.14.0-rc8 (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Error: Unknown chip 'S25FL128S' specified.
Run flashrom -L to view the hardware supported in this flashrom version.

(3) Tried to read the chip first. It could not determine the chip type.

./flashrom -p internal:laptop=this_is_not_a_laptop -r file_name.bin
flashrom v0.9.8-rc1-r1883 on Linux 3.14.0-rc8 (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
========================================================================
WARNING! You may be running flashrom on an unsupported laptop. We could
not detect this for sure because your vendor has not setup the SMBIOS
tables correctly. You can enforce execution by adding
'-p internal:laptop=this_is_not_a_laptop' to the command line, but
please read the following warning if you are not sure.

Laptops, notebooks and netbooks are difficult to support and we
recommend to use the vendor flashing utility. The embedded controller
(EC) in these machines often interacts badly with flashing.
See the manpage and http://www.flashrom.org/Laptops for details.

If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
========================================================================
Proceeding anyway because user forced us to.
Found chipset "Intel Avoton/Rangeley".
This chipset is marked as untested. If you are using an up-to-date version
of flashrom *and* were (not) able to successfully update your firmware with it,
then please email a report to [e-mail] including a verbose (-V) log.
Thank you!

Hi Idwer
I could not access the svn based link. Also the changeset link is not accessible.

So instead I have download it from https://github.com/jhcloos/flashrom as it stated that “Mirror of svn://flashrom.org/flashrom”

Once I try to compile it, I see following error. Can you pls help.

flashrom > make

Replacing all version templates with 0.9.8-rc1-r1883.

Package libftdi was not found in the pkg-config search path.

Perhaps you should add the directory containing `libftdi.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libftdi' found

Package libusb was not found in the pkg-config search path.

Perhaps you should add the directory containing `libusb.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libusb' found

Checking for a C compiler... found.

Support for that particular chip is present in development code, see subversion revision r1858 (
http://tracker.coreboot.org/trac/flashrom/changeset/1858 ).
You can obtain the development code through the steps mentioned here:
