Fwd: Setting page size in AT45db081d spi flash

Beware the AT45DB081D version is one time programmable for page size so that, I believe, the existing code is acting correctly as only the change from 264( default shipped state) to 256 bytes is allowed and only once. The E version allows the change up to 10,000 times! See chapter 13 of the D specification. I think we need a specific new flashrom device type for the AT45DB081E-264/256 family unless you have a better idea Regards Rob -----Original Message----- From: Shreeyash Pandey <shreeyash335(a)gmail.com> To: rh100605(a)aol.com Sent: Tue, 9 Aug 2022 10:40 Subject: Re: [flashrom] Setting page size in AT45db081d spi flash >What I was looking for was maybe a flag that defined the page size required >and altered it if necessary. This would be great. I suspect other AT45* chips may have this feature as well, they'd benefit from a universal scheme. Are you able to read the status register without any mods?. The man page makes it clear that ch341 doesn't support any parameters. Something like `flashrom -p ch341:read_status` is what we need. Moreover, What output does --wp-status produce? >I am not a contributor to Flashrom but any mod I make I would like to share >with others. I believe it would be better if a maintainer came up with a >scheme that fitted all spi flash that you support with different page sizes. Totally. I'd be up to volunteer help if needed.

The rest of the code is very aware of page size on read/write/erase, so needs to read the status register to work correctly The programmer I am using is the CH341A modified to work at 3.3v As I see it I would have to have 3 builds of Flashrom 1. Set 256 page size 2. Set 264 page size 3. as before modification to perform write and reads What I was looking for was either a CLI flag that allowed me to issue a one time command. Dangerous I know ! Or maybe a flag that defined the page size required and altered it if necessary. I am not a contributor to Flashrom but any mod I make I would like to share with others. I believe it would be better if a maintainer came up with a scheme that fitted all spi flash that you support with different page sizes.

However, I am thinking of a hack you could use here. File at45db.c implements the operations of your chip. We could modify one of the functions here that we shall use to send our four bytes of data. The very first function `at45db_read_status_register` is simple enough and should get the job done. Replacing 'AT45DB_STATUS' with '0x3d, 0x2a, 0x80, 0xa7' will send these bytes to the chip when we ask flashrom to read the status register for us. I've attached the modified file with this email. Diff it, if you may to see the difference. Re-compile flashrom by following build instructions in the README. Now read the status registers, this should send our string to the chip, re-configuring it. Reading status registers, I believe depends on the programmer? (Which one are you using?). There's very little on this in the man page except for the section on SPI Status Register for the dummy programmer. See if that is of any help. Alternatively, you could modify some other function in a similar manner. If you are not so sure about this, maybe wait for the more experienced folks around here to see your message. I am only getting started with hardware hacking.

The read operation worked well using the Flashrom device set as AT45DB081D I bought some more used AT45DB081E chips to write the saved image and Flashrom objected by stating that the image was too big by 32767 bytes I edited image by removing the last 32767 bytes and Flashrom wrote the used chips and verified successfully using the device setting AT45DB081D While reading the datasheet I noticed that the AT45DB081D/E has two page sizes 256 and 264 bytes which explains the 32767 bytes difference in image sizes It seems FlashROM is aware of the page size setting! However I cannot see how read the status register to see the page size set or how to change it using the 0x3D 0x2A 0x80 0xA6 / A7 command as described in Chapter 11 of the AT45DB081E datasheet To summarise I want to change the page size of an AT45DB081E back to 264 to repair the radio and cannot see how to use Flashrom to do it Regards Rob _______________________________________________ flashrom mailing list -- flashrom(a)flashrom.org To unsubscribe send an email to flashrom-leave(a)flashrom.org

libflashrom rust binding
by Evan Benn 09 Aug '22

09 Aug '22

Hello flashrom, I have uploaded 2 CLs implementing a libflashrom rust binding: https://review.coreboot.org/c/flashrom/+/65280 https://review.coreboot.org/c/flashrom/+/65281 The first creates a bindgen (https://github.com/rust-lang/rust-bindgen) 'thin' binding generated from the header. The second creates a 'fat' binding, translating from more idiomatic rust into the libflashrom API calls. The fat binding is not complete, I have added only the parts I am using. I have also added the first user of the fat binding, flashrom-tester: https://review.coreboot.org/c/flashrom/+/65282 I think the first question is is the flashrom community happy to have these bindings live inside the flashrom git repo? They could live in their own separate repos, but keeping them with flashrom will make keeping up with libflashrom API changes more straightforward. Otherwise please review the implementation if you are interested. Thanks Evan Benn

Setting page size in AT45db081d spi flash
by rh100605＠aol.com 07 Aug '22

07 Aug '22

I have used Flashrom to backup a memory image in a radio using the AT45DB081E spi flash memory. The read operation worked well using the Flashrom device set as AT45DB081D I bought some more used AT45DB081E chips to write the saved image and Flashrom objected by stating that the image was too big by 32767 bytes I edited image by removing the last 32767 bytes and Flashrom wrote the used chips and verified successfully using the device setting AT45DB081D While reading the datasheet I noticed that the AT45DB081D/E has two page sizes 256 and 264 bytes which explains the 32767 bytes difference in image sizesIt seems FlashROM is aware of the page size setting! However I cannot see how read the status register to see the page size set or how to change it using the 0x3D 0x2A 0x80 0xA6 / A7 command as described in Chapter 11 of the AT45DB081E datasheet To summarise I want to change the page size of an AT45DB081E back to 264 to repair the radio and cannot see how to use Flashrom to do it RegardsRob

Restructure shutdown functions and remove global state
by Joursoir 04 Aug '22

04 Aug '22

Hello everyone, Today I had a first meeting with my mentor Anastasia. And I'm looking forward to see Thomas as soon as possible. We've discussed our project goals, initial tasks and current state of the code. My next tasks: 1) Move all par masters to new API. It includes reducing the use of static global variables by storing them in a specific programmer data structure. 2) Introduce default shutdown function that can be very useful. We already have a patch for it: https://review.coreboot.org/c/flashrom/+/54890 It will be done in small steps/commits. So I hope to send a first patch soon. -- Joursoir

Board confirmed: Supermicro X7SPA-H
by Jim MacKenzie 04 Aug '22

04 Aug '22

Hi all, New subscriber. The Supermicro X7SPA-HF board is listed as specifically allowing BIOS updates using flashrom. I can confirm that the Supermicro X7SPA-H board (which is similar but not identical) also works with flashrom. I used flashrom to update the BIOS from 1.2a to 1.2b earlier this week. I've also used it to update my PC Engines APU single-board computers, but this compatibility is already noted and in fact sanctioned by PC Engines as the best way of doing the coreboot update on this platform. Thanks! I'll be watching with interest. Jim

flashrom failure report

Hi, I'm trying to flash the rom of a bricked Chromebook. I've tried multiple times, removing and reattaching the ch341a. The rom chip is still attached to the motherboard (I've never soldered). Any help would be appreciated!
