[OpenOCD-user] Altera Cyclone V Configuration

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

Hi Paul,

I did some searching, and it looks like the Tcl scripts we discussed are 
not open source.

The testee target type you suggested did work, but the target type doesn't 
support memory commands. 

The flash configuration you gave me appeared to configure at first, but 
then it failed later with an 'Unknown flash device (ID 0x00000000)' error. 
Could the reason for this be because I am talking to the flash through the 
FPGA software? 

In the end, it appears that I need a driver that speaks over the Altera 
JTAG and can write and read memory. Are my assumptions correct?

I did a grep of the source code, and the closest thing I saw that appeared 
to support anything related to Altera is the or1k target type. I'm not 
sure how that maps to a cyclone V FPGA.

Here is the grep snippet:
src/target/openrisc/or1k_tap_vjtag.c:/* Contains constants relevant to the 
Altera Virtual JTAG
src/target/openrisc/or1k_tap_vjtag.c:   LOG_DEBUG("Initialising Altera 
Virtual JTAG TAP");

However, this bit of Altera support looks to be a piece of a more 
substantial driver (openrisc) and not standalone support.

Any thoughts?
