I submitted a patch two weeks ago for SF100 with firmware version 5.5.1, but it has not been acked yet though. My (limited) experience with flashrom was that the mainline does not support SF100 with 5.5.1 firmware. Amongst the problems I encountered was that the Read Status Register 1 reply was incorrect for (at least) WEL and BUSY bits on a standalone W25Q64BV part. Possibly the other bits (e.g. SRP0) were also affected…
So if you can’t find a hardware reason for your problems you could check if my patch solves your problems. /Regards, Pablo -------------------------------- Senior Software Engineer FlatFrog Laboratories AB From: flashrom [mailto:[email protected]] On Behalf Of David Hendricks Sent: Wednesday, September 10, 2014 12:48 AM To: Sofer, Yehoshua Cc: [email protected] Subject: Re: [flashrom] Dediprog SF100 problem On Tue, Sep 9, 2014 at 4:43 AM, Sofer, Yehoshua <[email protected]<mailto:[email protected]>> wrote: Hi, I have Dediprog SF100 programmer with firmware version 5.5.1 When I try to write to the chip I got an error: “Some block protection in effect, disabling... Block protection could not be disabled!” Is there any way to resolve this? Is the chip you are trying to reprogram soldered onto the mainboard and, if so, is the write-protect pin grounded? Does the chip you are using have a "one time program" function enabled that will permanently enable block protection regardless of the write-protect pin state? For example, if you have a W25Q64DW and both SRP1 and SRP0 are set, then the status register protect bits become permanently locked.
