After that in the directory "/home/promwad/microchip_buildroot/buildroot-external-microchip/board/microchip/polarberry" you can find script for board flashing.
2+
3+
There are 4 scipts:
4+
1) Program_HSS_to_eNVM.sh
5+
2) Program_UBOOT_to_eMMC.sh
6+
3) Program_LINUX_to_eNVM.sh
7+
4) Program_ALL_to_Polarberry.sh
8+
9+
and settings file: FLASH_CONFIG.CONF
10+
11+
Script is used to burn images to the Polarberry board.
12+
13+
The 1th is used to program ONLY HSS bootloader umage to the Polarberry board.
14+
The 2th is used to program ONLY UBOOT image to the Polarberry board.
15+
The 3th is used to program ONLY LINUX (Kernel and root filesystem, bith) image to the Polarberry board.
16+
The 4th is used to program ALL (HSS, UBOOT, LINUX) images to the Polarberry oard.
17+
18+
19+
The 1th script can be used with virgin Polarberry boards and requires ONLY JTAG connection with the board.
20+
The 2th script can be used only after 1th was used (it means UBOOT programming requires HSS was installed before)
21+
and requires JTAG and UART connection with the board.
22+
The 3th script can be used only after 2th was used (it means Linux programming requires UBOOT (as HSS toot)
23+
was installed before) and requires JTAG, UART and ETHERNET connection with the board.
24+
The 4th script runs 1,2,3 one-by-one and do all thunigs that do 1,2,3 in automatic mode and requires JTAG
25+
UART and ETHERNET connection with the board. Can be used with virgin Polarberry boards too.
26+
27+
Before script can be used, you need to fix values in FLASH_CONFIG.CONF according to your PC.
28+
The file contains strings with comments, so you can advice what you need:
29+
30+
BUILDROOT_DIRECTORY - here you need to set PATH to the buildroot you are using
31+
UART_DEVICE - here you need to set the name of the UART in your system. (/dev/ttyUSB1 for example)
32+
DEVICE_IP - here you need to set IP ADDRESS that will be set on the board during flashing.
33+
It shall be one of the free/unused IP addresses from you network.
34+
35+
PC_IP - here you need to set IP ADDRESS of the PC you are using. (It can be obtained via "ifconfig" command)
36+
IMAGE_NAME - here you need to set file name with LINUX image that is placed on the TFTP server
37+
(default value is "fitimage_polarberry.itb", and this file is built by buildroot and placed in "output/images" directory)
38+
39+
40+
To start building images via buildroot you need to run this command in buildrood sources:
41+
1) "make sundancedsp_polarberry_defconfig BR2_EXTERNAL=../buildroot-external-microchip"
42+
(where BR2_EXTERNAL shall point to the mbuildroot microsemi sources).
43+
44+
2) "make"
45+
Building will take time. Succesfull building will finish like this:

To flash the images to the Polarberry board:
99+
1) Fix FLASH_CONFIG.CONF file in the board/microchip/polarberry directory.
100+
2) Power ON the Polarberry board
101+
3) run "Program_ALL_to_Polarberry.sh", and wait until all finished.
