W836xx: Lenovo T530: flashrom -V

Hello flashrom team, Please find appended a problem report of a failed attempt at probing the flash on T530. I would be happy to assist with testing and have means of recovering if the flash content should get corrupted. It looks like flashrom currently can not even get to reading the flash on this model.

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 https://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.

There are several CONFIG_* variables that can be (un)set when you build flashrom. They are listed under "Default settings of CONFIG_* variables" in the Makefile, and you can change the defaults however you like. You probably only need CONFIG_INTERNAL enabled for your desired use case. Alternatively, you can look at the output of the make command to see what's being included by default and override the default. For example, to explicitly disable USB Blaster you can use run "CONFIG_USBBLASTER_SPI=no make". -- David Hendricks (dhendrix) Systems Software Engineer, Google Inc.

Query Reg excluding the dependency with the libusb and libftdi
by RAJESH DASARI 25 Oct '16

25 Oct '16

Hi , Could some one please tell me is there any way to remove the dependency with the libusb and libftdi while building the flashrom binary . I use flashrom tool only to the flash the BIOS not for any USB device. I don't need support for FT2232, Dediprog or USB-Blaster. Thanks, Rajesh Dasari.

FreeBsd killed my BIOS
by Christopher Robinson 21 Oct '16

21 Oct '16

After a clean install of FreeBsd, my Sun Ultra 20 x86 AMD64 desktop would not reboot.I only got the Sun Microsytems logo on my monitor, nothing else happened. I think I needto reflash the BIOS and would like to do this with flashrom. However, I see that no live cdsare available. I plan to try Hiren's (earlier on I tried out systemrescue for another issue,with no success). However, I don't see how this will boot the system without first flashing theBIOS, if that is the problem. Sort of a Catch-22. The same seems to apply to Parted Magic.

There are various existing open source tools based on libftdi which write the EEPROM which does the same thing as FT_PROG. Please note that FT_PROG writes the configuation EEPROM of the FTDI chip, not the flash chip storing the firmware of the CC3100/CC3200. > If the FTDI D2XX is significantly different you can create a new file > (ftdi_d2xx.c, for example), and use ft2232_spi.c as a template. I think the FTDI D2XX library has a license incompatible with flashrom. If you want to replace TI CCS UniFlash with flashrom, it would make sense to check if any protocol documentation for the UART-based flashing exists. In that case you won't need D2XX or libftdi.

Yes, I already have seen that switch on the side of the Chromebook and flipped it on, Seems like that didn't help with disabling Write protect. My best guess is it's somewhere on the motherboard.

If it's Alex, then you'll want to check this page: http://www.chromium.org/chromium-os/developer-information-for-chrome-os-dev… Unfortunately the page for Alex doesn't have the WP switch circled, and it's been so long that I forgot where it is. It *should* be a jumper, though. I seem to recall that there is a plastic shroud near it to guard against potential tampering thru the exhaust grill or SD card slot. PS.
