CHIPSET: Intel Gemini Lake
by Prem Raghvani 04 Oct '21

04 Oct '21

Hello there! I recently tried to run "flashrom" on my Chromebook and it seems that the Intel Gemini Lake chipset is unsupported. Is there any other documentation or any way I can help in getting this chipset supported? -- *Many thanks and best of wishes* *Prem Raghvani* *E: prem(a)raghvani.com <prem(a)raghvani.com>* *W: premraghvani.xyz <https://premraghvani.xyz>*

Choosing a bigger erase block size
by Buhrow, Simon 27 Sep '21

27 Sep '21

Hi, choosing the best fitting erase block size can safe a significant amount of runtime. That´s why I would like to check if this can be improved. Just to get the right starting point, here some thoughts to be discussed from my point of limited view: As I understand the code, the algorithm for standard erase operation (e.g. before writing some random data) is this: 1) take the first entry of `flash->chip->block_erasers` 2) try to erase using this parameters 3) if check_block_eraser() fails try the next entry of `flash->chip->block_erasers` In this case the first entry given to `block_erasers` in `flashchips.c` is as the default entry used for erase operation for the given flashchip. As the first entry normally goes with the least block size this should work in almost every case. But on the other hand this is generally the worse choice regarding to run time if a erase operation with a bigger erase size would do the job as well. A) Would it be reasonable to just change the order and go from the bigger block size to lower block size? So the biggest size block erase operation is handled as a default and only in case it does not fit an erase operation with lower block size is used. I might have overseen some important aspects, so here just some other options: B) Make `block_eraser` entry selectable via cmd line parameter C) Add timing values of erase operations to flashchips.c and calculate and choose best runtime Let me know what do you think.

Flashrom tutorial
by piotr.strek.96＠wp.pl 23 Sep '21

23 Sep '21

Hi, I would like to try and flash my chip with flashrom but i have no idea if this software works without external programmer. So am i able to use it without external programmer and if yes where is the tutorial on what files to download and what commands to use. I know my chip model is supported because when i used Afudos and FPT tool it showed my chipset model and its listed under flashrom tested and working models.

Trying to use your utility script
by Andre Polidoro 21 Sep '21

21 Sep '21

Came across this error message when I was attempting to run your script on my google pixelbook. Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... 000000-0xffffff:R Reading 16777216 bytes starting at 0x000000. ignoring error when reading 0x0-0xffffff done. Good, writing to the flash chip apparently didn't do anything. This means we have to add special support for your board, programmer or flash chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! This is the set that the program said it didn't recognize.
