[RSU] Can't establish UART connection to perform remote system update on MAX10

Edit: the problem seems to be the nios 2 software:

I want the nios 2 software to be located in the UFM, but I'm not really sure how to do this.

In NIOS 2 SBT Eclipse, I created the BSP file for my device and made an application containing the remote_update.c file of the example project from AN741 which includes the UART update handling interface.

Then I build the mem_init_generate.

In the QSYS/Platform designer, the On-Chip Flash Intel FPGA IP is used, under "Flash Initalization" i checked "user created file" and linked the .hex file i created from my application. Qsys file was generated, project compiled and .sof files converted to .pof and put onto the FPGA with the programmer.

What's the correct way of getting my application into the FPGA?
