Error F03013, verification failure / programmer writing random value

[fletchryde2112]

Hey all,

I was recently assigned to a project that involves flashing a custom board with an XE216-C20 chip and onboard flash memory, IS25LP080D.

However, upon following the given documentation and running the command xflash bin/<targetfile>.xe I am presented with the following error:

Code: Select all

.

XFlash_Builder_Binary::GetSearchLimitPadding : current size (f000) 0

Error: F03013 Failed to run : 0x7ffc445bae80.

It seems here that, if I understand this correctly, the programmer tries to write a 0 to a location where a 0x37 should be written. Then when it tries to verify the value it gets confused and shuts down. What could be the problem here?
I've tried declaring different options in my environment but all to no avail (such as specifying the partition size, i have yet to change the spi settings), partially due to my current lack of experience with the XMOS architecture.

The board is a verified design and has worked in the past. We recently sourced production from a different company though and the board I am using is a part of that batch. Running the .xe with xrun --xscope bin/<targetfile>.xe is successful.

For reference, the .xn file entry regarding the flash device is is as follows:

Code: Select all

 .

 69   <ExternalDevices>
 70     <Device NodeId="0" Tile="0" Class="SQIFlash" Name="bootFlash" Type="ISSI_IS25LP080D" PageSize="256" SectorSize="4096" NumPages="4096">
 71       <Attribute Name="PORT_SQI_CS" Value="PORT_SQI_CS"/>
 72       <Attribute Name="PORT_SQI_SCLK"   Value="PORT_SQI_SCLK"/>
 73       <Attribute Name="PORT_SQI_SIO"  Value="PORT_SQI_SIO"/>
 74     </Device>
 75   </ExternalDevices>

Any suggestions regarding this issue are much appreciated. Thank you!

Has anyone experienced a similar issue in their custom builds? I have been unable to solve the problem as of yet.

On certain boards in the batch, running the following commands worked:

Code: Select all

xflash -v bin/<path> -o outfile.bin
xflash -v --target-file src/<path> --erase-all
xflash -v --target-file src/<path> --write-all

but the results of this were inconsistent, i.e. many of the boards did not flash at all. And on the boards that flashed, I get USB ERROR -71 upon plugging the device in (fit for a different topic).

Site 0 has ID 0x9d6014: So the program read the correct device ID from the flash: This corresponds to the IS25LP080D part.

It then programmed one page and read it back to compare and found the first byte of the page was 00 and it should have been 0x37.

Could be a problem with the quad enable bit not being set in flash? This would stop the read working.

What version of tools are you using, and the full xmos device part number?

Cheers,
Joe

Hi there and thank you for the response!

Could be a problem with the quad enable bit not being set in flash? This would stop the read working.

I modified my .xn file to look like this:

Code: Select all

<ExternalDevices>
 70     <Device NodeId="0" Tile="0" Class="SQIFlash" Name="bootFlash" Type="ISSI_IS25LP080D" PageSize="256" SectorSize="4096" NumPages="4096">

 72       <Attribute Name="PORT_SQI_SCLK"   Value="PORT_SQI_SCLK"/>
 73       <Attribute Name="PORT_SQI_SIO"  Value="PORT_SQI_SIO"/>
 74       <Attribute Name="QE_REGISTER" Value="quad_spi_qe_location_status_reg_0"/>
 75       <Attribute Name="QE_BIT" Value="quad_spi_qe_bit_6"/>
 76     </Device>
 77   </ExternalDevices>

but I'm still getting the same error.

What version of tools are you using, and the full xmos device part number?

Back when the project was originally built, the developer was using XTC 15.2.1. I tried building with that version but I was still getting the same errors. I am now currently running XTC 15.3.0.
The chip I'm using is the XE216-512-TQ128-C20.

Thanks again!

As an update, I was actually able to flash one of the other boards (by sheer luck, I suppose, as it only worked after trying over and over again... maybe a hardware bug has popped up) and plugged it into a Mac, where the device enumerated. Although I'm not too sure that the problem is solved here as the rest of the boards supposed functions do not work. So maybe back to the drawing board here.
