Hello, here are the test results for "Found Micron/Numonyx/ST flash chip "M25P16" (2048 kB, SPI)". Erase seems to work, but write fails. I tried it with an Arduino Uno (http://www.flashrom.org/Serprog/Arduino_flasher). Output is attached. Greetings

Hi and thanks for your report! I think the most probable causes are 1) a flaky chip, 2) flaky connections, but I am not sure. To test for flaky connections please re-read the chip a few times and compare the results. One way to do that is using the verify command multiple times: ./flashrom -p serprog:dev=/dev/ttyACM0:2000000 -Vv test.rom If it always fails like it did for writing (first byte/failure being Expected=0x55, Found=0x4b, and a total of 0x8399d unexpected bytes), then at least the clock, MISO and MOSI connections should be ok. What happens if you write the same image again? The number of unexpected bytes seems rather huge to me (more than half a MB) to be just a flaky chip, but erasing apparently works, so it cant be a simple write protection. What does the following command print out? hexdump -e '/1 "%02X\n"' test.rom | grep -v FF -c (it should show the number of bytes in test.rom that are not all ones, i.e. 0xFF).
Output is attached.

OK that all sounds like a dying chip to me, although I can't explain the symptoms in details. Fried electronics are even harder to understand than working ones ;)

The baud rate of the serprog module does change the communication rate between the micro controller and the host PC. That of course depends on the configuration of the Arduino and is usually fixed, and probably irrelevant in your case. What might be more interesting is the clock signal the micro controller applies to the flash chip. That can be changed by adding ",spispeed=..." to the programmer parameter, and only if the serprog implementation in the Arduino supports it. See manpage for details of the parameter.

OK
Lange Rede kurzer Sinn: Ich schaue das ich einen neuen Chip organisieren kann und teste damit. Bez. es kann auch sein das es am Programmer und gar nicht an flashrom liegt!
Yes, I would definitely try to get another chip if you want to get some device working (again) reliably. You can probably use many other flash chips because most of them are very similar (same pin layout, mostly equal protocol)...
Eine andere Frage: Wiso werden die AT45DBxxx Chips nicht unterstützt? Gibt es da eine möglichkeit diese zu unterstützen?
but there are exceptions. The AT45DB series is such an exception, but thanks to the work of Aidan Thornton and myself they are supported now. You need at least flashrom revision 1723 (which is included in 0.9.7). Be aware of the different pin layout! -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
Hello Stefan, ok then i try to write in English. Hope you understand my bad English ;-) I have tried to stabilize the Vcc with an additional Capacitor and cut the cables (to minimize the length), but with no luck. I'm not sure if the Flash is really broken. Maybe the Programmer has a Problem (is unstable). Sometimes the arduino "locks up" and i have to unplug and plug the USB again. :-\ Also tried with the parameter "spispeed=xx" but same (bad) results. I have an AT45DB011B chip here, but unfortunately this chip is unsupported. :-( Not sure what the difference between the "B" and the "D" is. But if i have time i try it with a AT45DB161D, this chip should be supported. I try to do some tests with other chips, let's see if it works. Have a nice day!

I think that is a known issue with the usb to serial converter of arduino unos. The converter is just another atmel microcontroller (ATMega<8, 16 or 32>U2), so the issue could potentially be fixed with a newer firmware... I dont know any details though. "Denis 'GNUtoo' Carikli" <GNUtoo@no-log.org> might know more. I have put him in CC but he does not have a lot of time lately.
Also tried with the parameter "spispeed=xx" but same (bad) results.
I have an AT45DB011B chip here, but unfortunately this chip is unsupported. :-( Not sure what the difference between the "B" and the "D" is.
The early AT45DB chips (<no suffix>, A, B revisions) do not support any identification opcodes so flashrom can not detect them at all (and I skipped adding dedicated support for them). I have never seen a user reporting one... maybe it works with "-c AT45DB011D -f" but I doubt it: most chips of the AT45DB family can switch between two major modes which change the observed address layout. Many of them indicate that in their status register... the early revisions do not (at least it is not documented in the datasheet)... the code for AT45DB011D is not designed to handle that correctly I think... so at least please do not try to erase/write if the chips contain something useful. :)
But if i have time i try it with a AT45DB161D, this chip should be supported.
The AT45DB161D is completely tested already, so there is no need to test it again from our side.
I try to do some tests with other chips, let's see if it works.
Good/better luck! ;) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
Hello again, can not say it in english, but in german: Ich denke deine "glückwünsche" haben geholfen!!! :-D Now i'm at home and tested again. And it works! ;-) Sometimes the reader still "locks up", but the verify is always good! Maybe my computer at work is bad or it's an ubuntu problem. Here at home i have LMDE (debian). The same chip works well here. I attached logs from read, write, erase and verify. If you need more tests, just tell me. The exact name of the chip is "*M25P16VG*". About the AT45DB161D: It's still red and says "no" on the homepage. Because of this i thought its not supported. And i test it with the AT45DB011B, let's see if it works. ;-) For the AT-Chips: The resistor R1 is needed? And Vcc connect to "hold" and "wp"?

Unlikely. Probably you just have bad luck with the timing of the USB data stream.
The same chip works well here. I attached logs from read, write, erase and verify. If you need more tests, just tell me. The exact name of the chip is "*M25P16VG*".
I'll mark the flash chip as fully tested and will commit that later together with other small changes.

Oh you are right. I forgot to update the wiki after merging quite a bunch of patches.
For the AT-Chips: The resistor R1 is needed? And Vcc connect to "hold" and "wp"?
The R1 is a so-called pull-up resistor. It pulls the voltage of /CS up to VCC. So the default if nothing is applied by the arduino is "unselected". Yes, /hold and /wp should be pulled up to high too (with or without a pull-up resistor does not matter too much because they are static anyway). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

It was newly added and is therefore missing. I am not updating the wiki after each commit that would change the wiki output, because it is quite some work and I dont think it is worth it. It is already marked as tested ok in the source code as you can see from the flashrom output (no messages about any unsupported operations). But thanks for noticing such details... not all of them are normal but bugs ;) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
Hi I have tow of this chips here and i try to erase and write it. But it doesn't work. First i thought the chip is broken, but i have tow and both chips generate the same error. The last line shows this: 0x100000-0x100fff:EFAILED at 0x00100000! Expected=0xff, Found=0xeb, failed byte count from 0x00100000-0x00100fff: 0xfe5 ERASE FAILED! I think something is wrong with flashrom. The error is always at 0x00100000. Any ideas? Something to try? Thx and greets.

Are you really sure? I ask me why i get this error only on this chip? I have tested a lot of MX-Chips and all worked fine. Only this chip does not work, and all of those chips stuck always at the same byte-count. So i am not sure if this is a serprog problem. ;-)

No, I am not 100% sure. But I don't trust that programmer at all. The indication I posted is written very late, way after the first error, but whenever I see it, I perceive the log as completely bogus. Where do you live btw? Maybe someone else could take a look at the chip with another programmer. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Yeah I'm thinking propably a problem of the serprog device - "serprog-duino". What is the exact hardware? (and link to firmware you used). Also, just for all serprog users, I'd like to hear reports (works/fails/faster/slower/???) from using this branch: https://github.com/urjaman/flashrom/tree/serprog-improvements It might be better or it might show the failures of your serprog device faster. I think the diagnostics are also slightly better for some cases. -- Urja Rannikko
