Full UEFI firmware install error on AKEMI
by David Horner 27 Jul '21

27 Jul '21

I received the following errors when attempting to install full UEFI firmware. The statements about rebooting conflict with each other too. The first says that a reboot can be done, the second says do not reboot in CAPS. I believe I followed the instructions correctly, all of the checks matched the instructions. Thank you in advance for help with what to do next. Please note that I am not including the many lines that preceded the error lines below.

all 1's - parity violation - No EEPROM/flash device found - compare_id: id1 0xff, id2 0xffff for *every* device tested
by James Feeney 17 Jul '21

17 Jul '21

Where to look for a cause? I have an only partially booting coreboot firmware image on a Geminilake Chromebook, apparently with a bad payload, but the flash device is obviously being read on boot, as can be seen on the AP console. Short version: Chromebook boot can read the flash device, but flashrom, through SuzyQable, only reads all "1's". Have a sparkfun SuzyQable connected to an Arch Linux box, and to the Chromebook. Have the desired result after running on the Cr50 console: > ccd reset factory > ccd testlab enable > ccd open Previously running flashrom from the stock ChromeOS would give 'Found GigaDevice flash chip "GD25LQ128C/GD25LQ128D"'. I have flashrom from both: git clone https://chromium.googlesource.com/chromiumos/third_party/flashrom WARNERROR=no CONFIG_MEC1308=no CONFIG_ENE_LPC=no make and git clone https://chromium.googlesource.com/chromiumos/platform/standalone-hdctools flashrom install These appear to both act exactly the same. Then: sudo ./flashrom -V -p raiden_debug_spi:target=AP results in "No EEPROM/flash device found", where: $ sudo ./flashrom -V -p raiden_debug_spi:target=AP |sed -n 's/.*$compare.*$/\1/p'|sort|uniq compare_id: id1 0xff, id2 0xff compare_id: id1 0xff, id2 0xffff From running flashrom, the Cr50 console says: [10398.332186 enable_spi_pinmux: AP] [10398.445490 usb_spi_board_disable] [10399.512358 AP UART on] [10399.514036 CCD state: UARTAP+TX UARTEC+TX I2C SPI USBEC+TX] [10399.728811 deferred_tpm_rst_isr] [10399.730025 AP on] [10399.730757 tpm_reset_request(0, 0)] [10399.731775 tpm_reset_now(0)] [10399.735335 tpm_init] tpm_manufactured: manufactured [10399.737601 tpm_reset_now: done] [10402.488852 PinWeaver: Loading Tree!] [10402.511275 PinWeaver: Loaded Tree. restart_count = 88] [10402.513121 Skipping commit] [10402.738718 Committing NVMEM changes.] This causes the Chromebook to boot, so then: [10408.218302 power button pressed] [10408.355704 tpm_rst_asserted] [10409.356714 AP off] [10418.538157 AP UART off] [10418.540362 CCD state: UARTEC+TX I2C SPI USBEC+TX] I don't know whether or not there should be a report of "usb_spi_board_enable" being called, but it is conspicuously not seen. If I understand, it appears as if flashrom reads and caches the flash device ID, but is just seeing all "1's". So - where is the problem? ... the flash device? the "pinmux" accessing the flash? the SPI channel? the USB channel? the Cr50? the raiden_debug_spi driver? some Cr50 configuration variable? some nasty hardware problem? I did run-across this odd thread: https://groups.google.com/a/chromium.org/g/chromium-os-discuss/c/yFevUZz9aac where running flashrom first gives "No EEPROM/flash device found", but subsequently reports, in that case, "Found Winbond flash chip "W25Q256JV_M" (32768 kB, SPI) on raiden_debug_spi." But, the reason for the different consecutive responses from flashrom were not explored there. Any thoughts about why the boot process can read the flash device, while flashrom only reads "1's" for the device ID? I did try running flashrom while specifying the device and forcing a read, but again, it just sees all "1's". Thanks James

Unknown programmer "ft2232_spi"
by Michael Leukert - AMPEGON 15 Jul '21

15 Jul '21

Hello! Do you have any idea why our flashrom v0.9.9 won't accept ft2232_spi as a programmer? We want to use flashrom for our ft2232_spi devices and the website flashrom.org/Flashrom/0.9.9/Supported_Hardware claims that flashrom v0.9.9 supports ft2232_spi. However, for some reason it just won't accept ft2232_spi as a programmer: - flashrom -p ft2232_spi flashrom v0.9.9-rc1-r1942 on Linux 4.15.0-45-generic (i686) flashrom is free software, get the source code at https://flashrom.org Error: Unknown programmer "ft2232_spi".

Please run "flashrom --help" for usage info. Surprisingly, even the man page claims that ft2232_spi is supported: - man flashrom ... -p, --programmer <name>[:parameter[,parameter[,parameter]]] Specify the programmer device.

Why not use usleep() instead of clock_gettime() loop for delay ?
by Patrick Star 13 Jul '21

13 Jul '21

I saw flashrom process use too many cpu time when I use it to write flashchip. Then I strace the process, and found too many "clock_gettime(CLOCK_MONOTONIC...)" system call. And located it to udelay.c line 39, in function clock_usec_delay(). So I replace the code with just usleep(), as below, static void clock_usec_delay(int usecs) { usleep(usecs); } And it still worked well, and use much less cpu time, and the time spend on erase&write a chip is basicly the same as before. Also I write image to a flashchip and read it out with the modified flashrom many times, and the read out results are always same as the original image. So why not use usleep() to save cpu time ? BTW: I have used flashrom many years, it helped me a lot, thanks for your work, very grateful.

stock flashrom vs Google forked flashrom on a chromebook running "stock linux"?
by James Feeney 01 Jul '21

01 Jul '21

When flashing the boot rom or the EC rom on, particularly, an Intel SOC chromebook, and running a "stock linux", instead of the original chromeos, is there any fundamental difference between the stock flashrom and the Google forked flashrom that would prevent the stock flashrom from working properly? Thanks James
