[OpenOCD-user] OpenOCD configuration question

[<cob...@se...>]

Hello,

My name is Coby Soss, and I am a software engineer at Schweitzer 
Engineering Laboratories.

I have a cyclone V FPGA that is connected to an ISSI IS25LP128F flash 
memory.

I have a system that is setup and working to program the ISSI flash via 
the FPGA. I am trying to replace the currently working solution with 
OpenOCD.

Currently, the FPGA and ISSI Flash chip are programmed via two steps:

1) Program the FPGA with a bootstrapping(flash loader) program.
2) Use the flash loader program on the FPGA to load the firmware onto the 
flash chip.

The Quartus II Programmer accomplishes step I.
Step two is currently done through the Quartus II system console with 
commands like the following Tcl script:

#a. Issue a WRITE ENABLE command
  master_write_32 ${::boardInit::masterPath} 0x20 0x06
  master_write_32 ${::boardInit::masterPath} 0x4  0x80010000

I have been able to configure OpenOcd to connect to the FPGA and perform 
step 1 successfully using an SVF file of the FPGA software.

However, I have not been able to do step 2 yet. I am trying to configure 
OpenOCD to work similar to the Tcl script. The main advantage is in having 
an abstract memory interface to the FPGA as opposed to trying to use JTAG 
directly to accomplish what the Tcl script is accomplishing. 

I haven't been able to figure out how to configure OpenOcd to handle these 
types of memory operations. I'm wondering if you have any suggestions for 
how to accomplish those kinds of memory read/write operations using 
OpenOCD.
