====================================

Advanced JTAG Interface (AJI) Client

====================================

In this repository you will find a Client-side

API implementation for accessing the JTAG 

server (jtagserv.exe or jtagd)

distributed by Quartus software from Intel.

Only JTAG interface supported. 

By default, it will attempt to connect

to the JTAG server on port 1309. See

store/examples/QUARTUS_JTAG_CLIENT_CONFIG.conf

if you need to connect to a remote server

========

Building

========

```

./bootstrap

./configure

./make 

./make install

```

=======

Example

=======

The following code, written with Arria10 in mind, will 

printout the IDCODE for each TAP and show any SLD hierarchy 

on the FPGA Tap(if available).

```

#include "aji.h"

void sld_node_printf(const AJI_HIER_ID* hier_id, const AJI_HUB_INFO* hub_infos);

void main() {

    DWORD hardware_capacity = 10;

    AJI_HARDWARE *hardware_list = (AJI_HARDWARE*) calloc(hardware_capacity, sizeof(AJI_HARDWARE));

    char **server_version_info_list = (char**) calloc(hardware_capacity, sizeof(char*));

    DWORD hardware_count = hardware_capacity;

    aji_get_hardware2(&hardware_count, hardware_list, server_version_info_list, 1000);

 

    for(unsigned int i=0; iidcode,

        (unsigned long) hier_id->position_n

    );

    if (hub_infos) {

        for (int m = 0; m <= hier_id->position_n; ++m) {

            printf("%d ", hier_id->positions[m]);

        } //end for m

        printf(")  hub_infos: ");

        for (int m = 0; m <= hier_id->position_n; ++m) {

            printf(" (Hub %d) bridge_idcode=%08lX, hub_id_code=%08lX", 

                m, 

                m == 0 ? 0 : (hub_infos->bridge_idcode[m]), 

                (hub_infos->hub_idcode[m])

            );

        } //end for m (bridge)

    }

}

```

CHANGE LOG

==========

 - 0.4.0

    - Bugfix: If you have 10 or more SLD nodes, then

	  previously opencod can segfault as the code

	  was trying to access memory beyond what was

	  allocated.

 - 0.3.0

    - Introduced aji_get_nodes_bi(...) which is a

      workaround for aji_get_nodes_b(...) for C

      program. It was noted that when as the 

      number of SLD nodes increases, hier_ids' 

      elements might not contain the correct idcode

      when the function is called from a C program.

      the "bi" version workaround this problem.
