Use flash S25FL064L

Postby hamtam » Fri Jan 19, 2018 1:14 pm

I try to use the S25FL064L Flash.
Datasheet for s25FL064

I created a description file "S25FL064L":

Code: Select all

256,                    /* 2.  Page size */

0x01,                   /* 23. WIP bit mask */


I tried to flash with:
xflash conet_8ch.xe --boot-partition-size 0x80000 --quad-spi-clock 15.62MHz --spi-spec S25FL064L

The output I got was:

I would add the QE_REGISTER & QE_BIT definitions to your XN file. That will eliminate the warning message about them. However, it looks like xflash made the correct assumptions about their settings, so I don't think just adding them to your XN file will fix your issue.

Did you notice that the values read back during the verify appear to be two bytes behind what was expected? I suggest that you try changing parameter #18 (READ dummy bytes) in your specification file to 3.

Also, use the xflash command with the --verbose flag to better understand what the tool is doing and to offer more details as to why it is failing.

Is there a list of flash devices that are supposed to work with the xCore-200?

I'm trying to use a Winbond W25Q16JV, with no luck. I see the same problem as listed in this thread: verify errors.

I've followed the procedure of specifying a new flash specification file, using the xflash --spi-spec option, and adding the QE attributes in the xn file.

It would be nice to know if this part is compatible and I'm just doing something wrong or if the register setup is different enough that it's not compatible.

Guessing something was missed in the new flash definition. Post all of the relevant files for a review.

Are you using this new flash on an XMOS XCORE-200 board for initial testing or on a custom board? For a sanity check, best to apply this new flash onto a XMOS devkit so we can rule out any custom hardware issues.

Are you using the --verbose flag? What does this reveal?

In practice, yes, it should be very possible to insert a QSPI capable flash device and have it supported using xflash tool chain. Post your results and let us see if it can be debugged. This is important to receive your feedback. Far too many "users" in this forum are quick to not post their results as suspecting it then working but that does not supply closure for the next reader. We do not work for XMOS nor compensated in any way by them. Our time is not free but do not mind sharing the help, when we can. In return, common courtesy is to post at least the results, either way. Even a simple thanks would go a long ways.

I'm attempting to use Winbond W25Q16JV quad flash on the xCORE-200 multimedia dev board.

Here's my device definition file:

Code: Select all

   
    26,                     /* libflash device id */
    256,                    /* page size */
    8192,                   /* num pages */
    3,                      /* address size */
    8,                      /* log2 clock divider */
    0x9f,                   /* SPI_RDID */
    0,                      /* id dummy bytes */
    3,                      /* id size in bytes */
    0xef4015,               /* device id */
    0x20,                   /* SPI_SSE */
    0,                      /* full sector erase */
    0x06,                   /* SPI_WREN */
    0x04,                   /* SPI_WRDI */
    PROT_TYPE_SR,           /* protection through status reg */
    {{0x1c,0x00},{0,0}},    /* SR protect and unprotect cmds */
    0x02,                   /* SPI_PP */
    0x0b,                   /* SPI_READFAST */
    1,                      /* 1 read dummy byte */
    SECTOR_LAYOUT_REGULAR,  /* sane sectors */
    {4096,{0,{0}}},         /* regular sector size */
    0x05,                   /* SPI_RDSR */
    0x01,                   /* SPI_WRSR */
    0x01,                   /* SPI_WIP_BIT_MASK */
     


Here's the .xn file modification:

Code: Select all

 
  <ExternalDevices>
    <Device NodeId="0" Tile="0" Class="SQIFlash" Name="bootFlash" Type="WINBOND_W25X16">
      <Attribute Name="PORT_SQI_CS" Value="PORT_SQI_CS"/>

      <Attribute Name="QE_REGISTER" Value="quad_spi_qe_location_status_reg_1"/>
      <Attribute Name="QE_BIT" Value="quad_spi_qe_bit_1"/>
    </Device>
  </ExternalDevices>
 


And here's the output of the xflash command:

xflash --boot-partition-size 0x40000 --verbose --spi-spec WINBOND_W25X16 --loader loader.o --factory app.xe

What I don't understand is, even though the location of the QE bit is specified, how does xflash know how to access status register 1? (The 2nd status register, as the first status register is register 0.) It's command 35h and 31h to read and write this register, respectively. These commands are not specified anywhere. Are they known by convention?

On the other hand, the W25Q16JVIQ part that I'm using has the QE bit set (quad mode enabled) from the factory, so I guess this doesn't need to be set by xflash, anyway.

@jallard, did you get this working?

See sections 30 & 31 of the xtime composer user guide for more details. There QSPI spec definition is different than the standard SPI definition posted by OP. Your definition file is for standard SPI command use only but the XCORE-200 current CPU series demands QSPI definition by default. However, if you plan to boot in standard SPI mode with your CPU then it is ok to use a standard SPI definition.

https://www.xmos.com/published/tools-user-guide

From the flash memory table shown in section 30, your Winbond flash is NOT supported as QSPI. However, you should be able to add the support as outlined in this document.

I didn't get the Winbond part working, even with the QSPI definition file. I determined that the QE (quad enable) bit location and status register setup in that part is not compatible. There''s no way that I can see to specify the locations of this bit / register in the definition options (even the QSPI definition).

I ended up using the IS25LQ040B, which I added support for by modifying the IS25LQ032B QSPI definition.
