Hi, that feature flag changes the behavior of the probe command and is exactly what was needed to get the AM29F010 version to work, thanks for digging this up. I have created a patch that splits the old definition into two, which allows to distinguish the chips. I'd be glad if you could test it if you still have the hardware. The patch is attached. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Author: stefanct Date: Mon Feb 1 00:17:35 2016 New Revision: 1922 URL: http://flashrom.org/trac/flashrom/changeset/1922 Log: Separate Am29F0xx from Am29F0xxA/B definitions. The earlier versions of the chip require 0x2AAA for probes thus split the definitions and set them to untested to provoke reports.

You may already be aware, but I wanted to post as this was advised as per the flashrom program. sudo flashrom -V -p internal flashrom v0.9.7-r1852 on Linux 4.3.0-7-generic (x86_64) flashrom is free software, get the source code at http://www.flashrom.org flashrom was built with libpci 3.3.1, GCC 5.2.1 20151022, little endian Command line (3 args): flashrom -V -p internal Calibrating delay loop...

Please send the output of "flashrom -V -p internal" to flashrom(a)flashrom.org with W836xx: your board name: flashrom -V as the subject to help us finish support for your Super I/O. Thanks. ======================================================================== WARNING! You seem to be running flashrom on an unsupported laptop. 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. ======================================================================== Aborting. Error: Programmer initialization failed. Christopher M.

[v3,2/2] ENE KB9012 EC flashrom patch - Bug report
by John Brown 30 Jan '16

30 Jan '16

Good day! I applied your most recent KB9012 flashrom patch to the latest flashrom copy, and tried to compile it for testing with my KB9012 chip. However, I have encountered the following error: flashchips.c:3209:19: error: 'FEATURE_ERASED_ZERO' undeclared here (not in a function) .feature_bits = FEATURE_ERASED_ZERO, ^ make: *** [flashchips.o] Error 1 FEATURE_ERASED_ZERO is not declared anywhere, neither in latest flashrom revisions, nor in older flashrom revisions. Dont know why nobody noticed this problem before me... Then, I thought it could be a good idea to replace this undeclared value with zero: .feature_bits = 0, Flashrom compiled successfully after this change, but unfortunately it cannot properly detect KB9012 chip that is attached to Bus Pirate through KB9012 adapter. Important log part is attached below (interesting, why it has not printed RDID stuff while probing for ENE KB9012) ... Probing for Atmel AT45DB642D, 8192 kB: RDID byte 0 parity violation. probe_spi_rdid_generic: id1 0xff, id2 0xffff Probing for ENE KB9012 (EDI), 128 kB: Probing for ESMT F25L008A, 1024 kB: RDID byte 0 parity violation. probe_spi_rdid_generic: id1 0xff, id2 0xffff Probing for ESMT F25L32PA, 4096 kB: RDID byte 0 parity violation. probe_spi_rdid_generic: id1 0xff, id2 0xffff ... Probing for Generic unknown SPI chip (REMS), 0 kB: probe_spi_rems: id1 0x7f, id2 0xff Found Generic flash chip "unknown SPI chip (REMS)" (0 kB, SPI) on buspirate_spi. Found Generic flash chip "unknown SPI chip (REMS)" (0 kB, SPI). === This flash part has status NOT WORKING 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(a)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! Read is not working on this chip. Continuing anyway. flashrom has no read function for this flash chip. Aborting. Raw bitbang mode version 1 Bus Pirate shutdown completed.
