That is my OTP content:

No security register bits should be set in the OTP by default: nothing is locked down.

(Probably stating the obvious, but don't try and set these unless you are sure its what you want - One Time really is One Time..)

Please can you try adding the "--force-pll-reset" option when running you xflash command.

I believe there is an issue changing the 2-wire boot link into the 5 wire link in your application XN and this should work-around it.

I'm not so practiced in using the cmd line tool, so I tried it with xTIMEcomposer,
and add this option by Other XFlash options:, please see Screenshot in the attachment.
I hope that is right.

I could flash, but the cpu still didn't boot.

That is my acctual XN file.

you can simply type the following in the command line to flash the board

Code: Select all

 xflash --force-pll-reset yourprogram.xe
whilst you are there, what is the result from the following command whist the design is in the broken boot state:

Code: Select all

xrun --dumpstate yourprogram.xe
(obviously change "yourprogram" to the name of your binary.. ;) )

Ok I tried something.

You mean that there went some wrong with the changing from 2-wire to 5-wire connection link.
Now I changed the all 5-wire connections to 2-wire.

Tada it worked, the cpu is booting :)



//back to 5-wire links
xflash --force-pll-reset ....
CPU would not boot.


xrun //dumpstate ....

Code: Select all

Glad its booting, you will be slowing down things a bit like that..

you should only need to change the boot-link in the XN, i.e. this one.

Code: Select all

<Link Encoding="5wire">
          <LinkEndpoint NodeId="0" Link="8" Delays="52clk,52clk"/>
          <LinkEndpoint NodeId="2" Link="XL0" Delays="1clk,1clk"/>
        </Link>
        <Link Encoding="5wire">
          <LinkEndpoint NodeId="1" Link="8" Delays="52clk,52clk"/>
          <LinkEndpoint NodeId="3" Link="XL0" Delays="1clk,1clk"/>
        </Link>
This way the XN file will match the boot-pins. The next tools release should fixe the upgrading the 2-wire to 5 wire after boot issue. --force-pll-reset option is normally a valid to work-around for this..

I wasn't shure wich LINK is the boot link. So I changed the first four LINKS, aren't the last two for USB?

Code: Select all

        
      <Links>
        <Link Encoding="2wire" Delays="3clk">
          <LinkEndpoint NodeId="0" Link="7"/>
          <LinkEndpoint NodeId="1" Link="0"/>
        </Link>
        <Link Encoding="2wire" Delays="3clk">
          <LinkEndpoint NodeId="0" Link="4"/>
          <LinkEndpoint NodeId="1" Link="3"/>
        </Link>
        <Link Encoding="2wire" Delays="3clk">
          <LinkEndpoint NodeId="0" Link="6"/>
          <LinkEndpoint NodeId="1" Link="1"/>
        </Link>
        <Link Encoding="2wire" Delays="3clk">
          <LinkEndpoint NodeId="0" Link="5"/>
          <LinkEndpoint NodeId="1" Link="2"/>
        </Link>
        <Link Encoding="5wire">
          <LinkEndpoint NodeId="0" Link="8" Delays="52clk,52clk"/>
          <LinkEndpoint NodeId="2" Link="XL0" Delays="1clk,1clk"/>
        </Link>
        <Link Encoding="5wire">
          <LinkEndpoint NodeId="1" Link="8" Delays="52clk,52clk"/>
          <LinkEndpoint NodeId="3" Link="XL0" Delays="1clk,1clk"/>
        </Link>
      </Links>

When I change the last two LINKS to 2-Wire, I get the Error:
xrun: First stage multi-node boot failed, please check XN file and Xmos link connectivity
Nevertheless, maybe I could now demonstrate my board on an exhibition next week.

Big thanks,
Sebastian
