There is a patch available at http://openocd.zylin.com/#/c/4876/ to support
flash chips with capacity more than 16 MBytes. However, please note that
depending on the particular type it might additionally be necessary to switch
the flash chip to 4-byte address mode, either always after power-up or through
non-volatile setting. The patch includes an appropriate command to configure
the flash, see manual for an example.
Please test and add a comment there.

** [tickets:#223] Erasure error when flashing PCI-e screamer card**
**Status:** new

Hi,
Have been getting an error which shows contents differ when I was trying to
flash my PCI-e Screamer card. I then followed the instructions to apply a git
patch to my openocd. The instructions i followed were at
http://blog.lambdaconcept.com/doku.php?id=products:pcie_screamer.
However, even after doing so, it still shows the error below. Does anyone have
any resolution to this?
$ sudo openocd -f flash_screamer.cfg
