    Using flashrom with the Papilio Pro

    All, Thanks for the explanation. It hadn't occurred to me to use the Papilio Pro as a programmer for things not on the board. I'd assumed the programmer was for programming things on the board already! The xc3sprog may be the way to go. Although i'd be happy with read-modify-write cycle. But the papilio programmer doesnt have an obvious "read out contents of chip" feature. Cheers Stephen

    Using flashrom with the Papilio Pro

    Ok i think i have the issue here.. The wiki says.. "The Papilio Pro includes a reset header (JP4) that can be populated with a jumper to hold the Spartan 6 FPGA in permanent reset mode. This frees up the JTAG Header to be used as an FT2232 JTAG/SPI/MPSSE Programmer." Unfortunately this doesnt seem to work. With a jumper in place i still get ID's back from the Spartan 6 and cannot see the SPI Flash on the JTAG chain. If the above statement is not accurate could we remove it from the wiki? I've spent quite a bit of time trying to solve this one (and nagged the flashrom guys) and it appears that the hardware doesnt support direct access to the SPI flash. I'd rather others didnt do the same.
  3. Hi, I've been trying to get flashrom v0.98 working with the papilio pro with not much luck. I had Jumper 4 closed off and tried flashing the boundary scan bit file with the loader too. No luck. Im not satisfied with the bitmerge approach to the flash rom management and i'm looking for other tools to manage this. One thing i did notice while trying to diagnose the issue is that the wiki page says.. Channel A is connected to the Papilio Pro in an Asynchronous serial UART configuration that is capable of speeds up to 2MHz.Channel B is connected to the JTAG pins of the Papilio Pro and provides very fast programming of the FPGA (500mS). However the circuit diagram shows the JTAG pins connected to port A. Could this be updated? If anyone has had any luck with flashrom program let me know. I also have a bunch of other JTAG programmers (Xilinx USB and USB Blaster) if anyone has had success with them.

    MX25L6445 SPI/BPI device not found in iMPACT

    Thankyou. That should suffice for now. I think adding "write binary file to specific address" would be useful for the loader at some point. The SPI flash is a little large to fill up in one hit and some tools to generally manage them would be nice (but who has the time .. ).

    MX25L6445 SPI/BPI device not found in iMPACT

    Is there a way to write an mcs file to the papilio pro? More specifically the problem I am trying to solve is to have a file that writes data sections to predefined addresses in the SPI flash. e.g. I want to put binary images at the 1M boundary, different ones at the 2M boundary (just an example). My core can read the spi flash happily by address (ported from the Atlys) but I cant find a way to write a binary file to a specific SPI address like i can with the Adept software. Cheers Stephen
