I'm trying to use this library to create an application to load different bitstreams, but I can't make it work! The hardware project I'm using has a reconfigurable partition with two reconfigurable modules. I'm using Kv260 and petalinux. I have tested this application with real hardware, and I used the fpgautil to load and remove the application, and it works well with it.
I modified the demo application to start loading only the static region of the PL, and it looks like this:
#include <stdio.h>
#include "libdfx.h"
int main()
{
int package_id_full,ret;
package_id_full = dfx_cfg_init("/media/dfx-static", 0, DFX_EXTERNAL_CONFIG_EN);
if (package_id_full < 0) return -1;
printf("dfx_cfg_init: FULL Package completed successfully\r\n");
ret = dfx_cfg_load(package_id_full);
printf("dfx_cfg_load: FULL Package completed successfully\r\n");
ret = dfx_cfg_destroy(package_id_full);
if (ret) return -1;
printf("dfx_cfg_destroy: FULL Package completed successfully\r\n");
return 0;
}
under the folder /media/dfx-static I have the following:
xilinx-kv260-starterkit-20232:/home/petalinux# ls /media/dfx-static/
dfx-static.bit.bin dfx-static_i.dtbo
The static bitstream has an AXI slave called SysInfo that I want to access.
In the console, I see the following:
xilinx-kv260-starterkit-20232:/home/petalinux# Dec 22 07:10:33 xilinx-kv260-starterkit-20232 kernel: OF: overlay: WARNING: memory leak will occur if overlay removed, property: /fpga-full/firmware-name

I see the device I want to read (/symbols/SysInfo_0) was loaded correctly, but when I try to read the register like this:

Shouldn't the library verify if the same overlay is already applied and remove it before applying a new one?
I removed the overlay that is loaded by default by removing the overlay, with
rmdir
Then it loads I still have the 1rst problem. So my question is what is the difference between using fpgautil and this library?
Thanks in advance for any support provided with this issue.
