Load reference design (Linux in SPI)¶

Prerequisites¶

• Access to Antelope through Smart Mission Lab

• Reference design files using Linux in SPI memory

Steps¶

1. Connect to EGSE Host with Antelope board

   my-machine$ ssh customer@egse-my-egse.egse.sml.lan
   customer@egse-my-egse:~$
   

2. Power on Antelope board

   customer@egse-my-egse:~$ sml power on
   Powering on...Success
   

3. Power on DPU but don’t release it from reset

   customer@egse-my-egse:~$ sml dpu power on
   Powering on...Success
   

4. Unpack reference design files

   customer@egse-my-egse:~$ mkdir reference-design
   customer@egse-my-egse:~$ cd reference-design
   customer@egse-my-egse:~/reference-design$ tar xvf /path/to/reference_design.tar.gz
   

5. List files in reference design directory

   customer@egse-my-egse:~/reference-design$ ls -lh
   total 14M
   -rw-rw-r-- 1 customer customer 1.5M Apr 11 07:14 boot.bin
   -rw-rw-r-- 1 customer customer 3.0K Apr 11 07:14 boot.scr
   -rw-rw-r-- 1 customer customer  12M Apr 11 07:14 linux.fitimg
   -rw-rw-r-- 1 customer customer   58 Apr 11 07:17 spi-flash-layout.txt
   

6. Check expected layout of reference design files in SPI flash memory

   customer@egse-my-egse:~/reference-design$ cat spi-flash-layout.txt
   0x000000 boot.bin
   0x4E0000 boot.scr
   0x500000 linux.fitimg
   

7. Program SPI flash memory with reference design files at specified addresses

   Note

   These operations might take several minutes depending on the size of the files

   customer@egse-my-egse:~/reference-design$ sml dpu boot-flash write 0 ./boot.bin

8. With reference design loaded to DPU’s SPI flash memory, you can go to Booting DPU.
