E1500 SPI config

[ricktendo]

Trying to make a config for the E1500 but instead of JTAG I want to do a SPI version, here is my config (I stripped out all of the jtag stuff but I may have removed too much)

Code: Select all

<Test>
   <Name>E1500SPI</Name>
   <Cat>Router</Cat>
   <Protocol>SPIFLASH</Protocol>
   <Endian>Big</Endian>
   <Memorys>
      <Memory>
         <Name>CFE</Name>
         <Type>1</Type>
         <Address>0x9C000000</Address>
         <Size>0x40000</Size>
      </Memory>
      <Memory>
         <Name>KERNEL</Name>
         <Type>1</Type>
         <Address>0x9C040000</Address>
         <Size>0x7B0000</Size>
      </Memory>
      <Memory>
         <Name>NVRAM</Name>
         <Type>1</Type>
         <Address>0x9c7F0000</Address>
         <Size>0x10000</Size>
      </Memory>
   </Memorys>
</Test>

Here is the error I get when trying to ID

What flash is this? Does it have JTAG port? It is always better to use JTAG port than direct SPI programming.

IT was done 2.5 years ago.

That video is with EJTAG connection, I prefer to connect to and power the SPI chip directly (because its easier to connect my soic8 test clip than to solder in that teeny, tiny jtag port)

What am I doing wrong with my config that the chip is not recognized?

OK, then post your chip info. You might need to add the flash to the xml.

Here is a pic I snapped with my usb microscope http://i.imgur.com/djMuKLq.jpg

Edit: here is the stuff I stripped out or edited from the EJTAG config

Code: Select all

   <IRLength>5</IRLength>
   <DMA>No</DMA>
   <ProbTrap>1</ProbTrap>
    <LVMode>1</LVMode>
   <Programram>0x80200000</Programram>
   <SPIFlash>1</SPIFlash>
   <SPIData>bcm5300spi.dat</SPIData>
   <Inits>
      <Init>
         <Address>0x18000040</Address>
         <Value>0x80000403</Value>
      </Init>
   </Inits>

Go to tools and new spi flash. Clone it from any 2564 and enter the id as ef,40,80 and you are ready to go.

WOW that was so easy, works like a charm now

Code: Select all

Copyright (C) 2010-2015
USB JTAG NT    0.77
Target: E1500SPI
-flshdct 9c000000
Found Address= 9c000000 W25Q64CV
-getram 9c000000 800000
Time 00:00:08 (.978)

Also: I still do not understand the "Init" trick you do to remove the first 32 bytes from tomato firmware, can you explain how it works a bit more?

[usbbdm]

Just remove the first 32 bytes.
You can use ldram with address minus 32 or save with address offset 32.
Or you can use external hex editor to do so.
