How to program sst49lf020a chip with raspberry pi?
by Craig Taylor 28 Jun '19

28 Jun '19

I am having trouble figuring out the correct pinout for the plcc32 chip to program with the raspberry pi. Here is the Data sheet https://datasheetspdf.com/mobile-pdf/574977/SST/SST49LF020A.html I know that I need to solder to pins VCC, HOLD, WP, GND, SCLK, SO, SI and CS however I have no idea what pins these are on the datasheet. If you have any input on this that would be awesome. I am looking to reprogram a bios on one of these chips Serious thanks in advanced.

Support using FTD2XX driver for FT2232H device
by Steffen Mauch 27 Jun '19

27 Jun '19

Hello, right now, I am working on a windows version of Flashrom based on the FTD2XX driver from FTDI instead of libFTDI. Thus, I would like to know if I should submit a patch such that the ‚ft2232_spi.c‘ can cope with libFTDI and FTD2XX via defines or crate a new driver. Best regards Steffen

[announce] flashrom v1.1
by Nico Huber 22 Jun '19

22 Jun '19

Dear flashrom followers, I'm pleased to announce that we released flashrom v1.1 after fixing a few minor compilation issues in v1.1-rc2. This is a feature release with a handful of new programmers and lots of new flash chips including, finally, 4-byte-address SPI flashes. You can find the complete release notes here: https://flashrom.org/Flashrom/1.1 The official tarball and signature here: https://download.flashrom.org/releases/flashrom-v1.1.tar.bz2 https://download.flashrom.org/releases/flashrom-v1.1.tar.bz2.asc Again, the hint for package maintainers: If you don't use Git or don't override flashrom's version string anyway, avoid the tarballs offered by tools like Cgit or Github. They don't contain any version information. Best regards, Nico

Programming Speed FTDI 2232H to N25Q128
by Buhrow, Simon 19 Jun '19

19 Jun '19

Hi, I´m using a N25Q128..3E to store a bitstream configuration for an FPGA. To program the flash I´m using an ftdi2232H chip. I have two ways how to program the flash (with the same ftdi chip!): Via the JTAG and the FPGA (which first loads a JTAG to SPI converter core to do so) or directly via SPI. I prefer the last way as it is with less possible error points and I suppose that it should be faster. My problem: Programming the flash directly via SPI is much slower than the indirect way through JTAG and the FPGA. I think that it does not has to do with the SPI clock frequency as it is even slower in indirect case. But I can observe a significant difference in the Idle time between two SPI sequences/packages. You can see that at attached screenshots. The idle time (red arrows) is 2 - 4 times longer in direct case (below) than in the indirect (above) (as there are about 16000 SPI sequences it really does matter). 1. I couldn't find any flashrom parameters to change idle time. Is there any? 2. When looking at the source code I found the function call 'ftdi_set_latency_timer' but can´t find the function definition. Does it has to do with the idle time? 3. Which function should I touch to change idle time if there is any to do so? 4. Any other advice about how to change the idle time? Regards, Simon

Print timestamps
by Buhrow, Simon 18 Jun '19

18 Jun '19

Hi, sometimes I like to know how long an operation took or when I started programming. That´s why I added some timestamp printouts. May be you want to add it to the sources or do it in a more elegant way? What´s about adding the timestamp printout to msg_cinfo ? Just a proposal... Regards, Simon

Flashrom and GD25Q32C
by flashrom＠gnuproject.org 10 Jun '19

Hello List, i have a bricked TP-Link router with GD25Q32C DIP8-chip, but flashrom supports only the GD25Q32(B). I can read this ROM with --force option, but no write :( What can i do? Whitch other options exitst for me to write to the DIP8-chip?

Flash chip in unknown state!
by Max Bell 08 Jun '19

08 Jun '19

Hello, Ijust discovered this project and thought I would try it out on a spare Gigabye GA-N3050-D3P board that I had in storage. Unfortunately, flashing the modified image back to the board fails during the verify step. The same thing happens when I attempt to write the original BIOS back to the board, so I'm stuck with a presumably bricked board. Below is (I hope) all the relevant information you need. I've also attached the original and modified BIOS images. Board: Gigabye GA-N3050-D3P Chip: MX25U6435F (8192 kB) Flashrom ver: 1.0.1 Using Raspberry Pi and Pomona 5252 for SPI interface Verifying flash... FAILED at 0x00000010! Expected=0x5a, Found=0xff, failed byte count from 0x00000000-0x007fffff: 0xc0d48 Your flash chip is in an unknown state. Thanks, Max Sent with [ProtonMail](https://protonmail.com) Secure Email.

Re: N25Q128A

I found the error: I had a signal integrity problem. The chip now is detected correctly as N25Q128..3E . All commands execute correctly. So please forget my las mail/post as the chip is already in the flashrom database and working fine!! (as my N25Q128A is a N25Q128..3E ) Sorry! Simon

Dear FlashromTeam, if it helps any, (ASUS-H110M-E M.2 board with GD25B128CPIG 16MB bios chip) flashrom -p internal flashrom v1.1-rc1-6-g7eb38aa on Linux 5.1.6-gnu-1 (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found chipset "Intel H110". 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 flashrom(a)flashrom.org including a verbose (-V) log. Thank you! Enabling flash write... Warning: BIOS region SMM protection is enabled! Warning: Setting Bios Control at 0xdc from 0xaa to 0x89 failed. New value is 0xaa. SPI Configuration is locked down.

This is most likely due to an active ME. Please see https://flashrom.org/ME for details. At least some flash regions are write protected.
