→Example #1: HelloWorld application
This section describes how to run freeRTOS HelloWorld example application on BORA using AMP (Linux + FreeRTOS). Plese follow the steps listed below:
* Place all the binary files into the host tftp directory:
** Kernel{{efn|The kernel must be built with the <code>UIMAGE_LOADADDR 0x8000</code> option. Please refer to [[Building_Linux_kernel_(BELK)|this page]] for more details.}}.: <code>uImage</code>
** Device Tree: <code>bora.dtb</code>
** First stage bootloader: <code>bora_FSBL.bin</code>
</pre>
* Reset the board to reboot with the new FSBL
* Add the following U-Boot environment variables{{efn|*<pre>program_fpga</pre>: Loads FPGA binary from TFTP and programs the bitstream*<pre>load_freertos</pre>: Loads freertos application binary from TFTP and writes application start address for core #2 *<pre>mem=${kernel_memory}</pre>: sets maximum kernel memory (1008M = 1024M - 16M)*<pre>maxcpus=${nr_cpus}</pre>: sets maximum Linux cores to 1.}}:
<pre>
setenv addcons 'setenv bootargs ${bootargs} console=${console},115200n8 cma=16M debug maxcpus=${nr_cpus}'
setenv fpga_file BELK/bora_design_wrapper.bin
</pre>
<pre>
run net_nfs
