Re: [flashrom] Winbond W25X16 successful programming

[Maurizio Cavalli]

Hi.
I downloaded the latest snapshot of flashrom as you suggested, and you will find the new log in the attached file.
There is yet a lot of "opcode 0x06 will be run as PREOP" lines: I deleted all of them but the first sequences.
If you need them, let me known. I can rerun the program anytime, and if this little job can help you, I will do it.

About the code for the PentiumM/82855GME: I'm sorry, but I have nothing to submit. Is was a my personal attempt to port linuxbios, but the activity was (too soon ?) stopped. The development tree was moved into the "old things limbo", from where it was deleted by a mistyped answer during disk maintenance.
Anyway, thanks.

Regards

Hi Maurizio,

thank you for your report. I will add your chip to the supported list.

The log of your flashrom version had thousands of lines like this:
Invalid OPCODE 0x06
 due to SPI master limitation, ignoring and hoping it will be run as PREOP

I have removed them from your log to make the mail smaller.

It would be great if you could test erase and write with the latest
flashrom from svn as well. The invalid opcode messages should have
disappeared.

Oh, that is interesting. So you do already have some code, but it is not
working yet? Could you please send that code to the coreboot mailing
list  so other developers can have a look. Maybe
someone has good docs for that platform.
