typo in SPI prettyprint?
by Pablo Cases 10 Sep '14

10 Sep '14

Hi, Browsed through the code and noticed a possible typo in sp25_statusreg.c: spi_prettyprint_status_register_bp (r1850) Shouldn't Block Protect 4 bit be shifted 6 steps instead of 5? ------------------------------------------------------------------------------------------ /* Common block protection (BP) bits. */ static void spi_prettyprint_status_register_bp(uint8_t status, int bp) { switch (bp) { /* Fall through. */ case 4: msg_cdbg("Chip status register: Block Protect 4 (BP4) is %sset\n", (status & (1 << 5)) ? "" : "not "); case 3: msg_cdbg("Chip status register: Block Protect 3 (BP3) is %sset\n", (status & (1 << 5)) ? "" : "not "); case 2: msg_cdbg("Chip status register: Block Protect 2 (BP2) is %sset\n", (status & (1 << 4)) ? "" : "not "); case 1: msg_cdbg("Chip status register: Block Protect 1 (BP1) is %sset\n", (status & (1 << 3)) ? "" : "not "); case 0: msg_cdbg("Chip status register: Block Protect 0 (BP0) is %sset\n", (status & (1 << 2)) ?

Re: [flashrom] Dediprog SF100 problem
by Pablo Cases 10 Sep '14

10 Sep '14

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:flashrom-bounces@flashrom.org] On Behalf Of David Hendricks Sent: Wednesday, September 10, 2014 12:48 AM To: Sofer, Yehoshua Cc: flashrom(a)flashrom.org Subject: Re: [flashrom] Dediprog SF100 problem On Tue, Sep 9, 2014 at 4:43 AM, Sofer, Yehoshua <yehoshua.sofer(a)intel.com<mailto:yehoshua.sofer@intel.com>> 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...

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.

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...

To whom it may concern : Hello, I read some command code about using the software but I didn't understand clearly how I can use it to read/write memory chips through FT2232D SPI port! Would you tell me how I can use it? or send an useful manual ... Thanks a lot...
